Calibration and organization and procedure. Determination of metrological characteristics. the procedure for submitting measuring instruments for calibration to the BoMS
Modern conditions market demand to constantly improve production technologies to ensure more High Quality product. Accordingly, the requirements for metrological support are becoming ever more stringent. It can often seem that metrological assurance is a fairly simple process, but it should not be overlooked that it is an indispensable element in areas such as industry, science or medicine, in which it is extremely important to achieve high accuracy in measurements.
They can - even without unforeseen events at the same time - be checked regularly by a weighty test. Compensation volumes: Geometric errors of coordinate measuring machines can be significantly reduced. The main component is a laser interferometer which automatically controls the reflector and is thus able to detect geometric deviations with maximum accuracy. Compared to traditional gauges, the system provides patented technology with unique torque accuracy to manufacturer specifications.
Modern metrological support has reached high level consumption, compared with the last century, when metrology was used only for scientific purposes, now it is impossible to imagine the production of quality goods and services without its use. In this regard, entrepreneurs have to independently introduce measurements into their production technology, after calibration. Accordingly, for qualitative metrological measurements, a special set of skills and knowledge is required.
Beads with a change in shape at the nanoscale serve as a reference optical interferometer. This fully compensates for the mechanical inaccuracies of rotating and tilting axes. Subsequently automated process The measurement system follows the path of the device throughout the workspace and continuously measures longitudinal changes with nanometer resolution. This allows you to determine if the measuring device specifications or whether service intervention is required.
Simple compensation values for scale factor and squareness can be obtained directly from the measurement results. Patented automatic beam alignment technology, compared to the bead calibration rod, greatly reduces the measurement time; In addition, the device is much more tolerant of displacement than a ball gage pad and does not require a second person to assemble.
If earlier verification and metrological certification of measuring instruments was carried out only by the body of the state metrological service, now calibration has completely changed this. Unlike verification and metrological certification, calibration can be carried out by any metrological service, provided that it has all the necessary conditions for calibration work. In addition, the metrological service is obliged to fulfill certain requirements. The main requirement for metrological services is the need to ensure full compliance of working measuring instruments with state standards. In other words, the calibration is included in the national system for ensuring the uniformity of measurements.
On average, the accuracy of the device can be increased in this way by 30%, in exceptional cases by more than 50%, said Josef Mutsch, who is of particular importance in terms of the required accuracy. and more accurate than the results of the calibration ball stand.
Mass of the calibration rod with spheres
It also adds a high degree of independence to service providers that previously car manufacturers had to do with correction data. The main direction of our activity is carrying out comprehensive research and examination of materials and calibration of measuring instruments. All our laboratories are accredited by the Polish Accreditation Center.
Distinctive features of calibration:
1. All decisions about the suitability and possibilities of using SI are made by users themselves.
2. The frequency of calibration is set by the owners.
The purpose of calibration is to determine the actual value of the SI metrological characteristic, after which the owner is able to decide on the further application of all the data obtained.
Air flow measurement - where and why
Its headquarters is located in Elbląg on Stocnjanova Street. Its headquarters is also located in Elbląg at ul. Stanislav Sulima 1 in the area of the Elbląg Technology Park. AT last days it really blows. Wind speed is the flow of air due to pressure differences. Measurements of the speed of air and other gases are made using anemometers. Air flow measurements are performed not only for meteorological purposes, but also in air conditioning and ventilation systems. Chimneys use electronic anemometers to carry out mandatory inspections of ventilation ducts and chimneys in buildings.
During the calibration, a specific MI is selected, and with the help of a reference or auxiliary MI, all valid readings are determined at a single point, points, or in a given range. After that, the value and is assigned to this SI. All actual values taken can be set both in real operating conditions and without regard to such conditions.
All measuring instruments, including anemometers, are calibrated in accredited measurement laboratories to confirm their correctness. In addition to the standard laboratory, the laboratory must be able to produce the appropriate measuring medium, in this case airflow.
Construction of a wind tunnel
For this purpose, the so-called. Aerodynamic tunnels that provide the correct air flow. The construction of such a tunnel turned out to be a big deal, because for this. laminar flow rather than turbulent flow, an appropriate flow channel shape should be used.
From the point of view of metrology, calibration differs from verification in that during the calibration, the actual value of the metrological parameters is determined, after which they are assigned to the MI of the calibration object, while during the verification, the metrological parameters are determined to be within acceptable limits.
Premises, environment
The main element that generates the air flow in the anemometer calibration tunnel is controlled by an inverter fan that draws air into the tunnel. At the entrance there are so-called. Honeycomb is built in the form of a honeycomb grid. This is the so-called. airflow rectifier. Another element of the tunnel is confusion. This is a flow channel with decreasing cross section. High-speed air undergoes adiabatic transformation. The decreasing cross section increases the flow rate and pressure drop.
When the channel section is reduced, there is a section in the fixed cross section that forms a measurement space, called the measurement nozzle. A calibrated anemometer will be installed here. The next element of the tunnel is a diffuser. It is a flow channel with increasing cross section. In the diffuser, the air flow slows down, which corresponds to the change in the kinetic energy of the flow into pressure energy.
How is calibration organized and carried out in the Republic of Belarus
General provisions calibration
Calibration can be carried out for those measuring instruments that are allowed for use on the territory of the entire republic, respectively, with STB 8004 and STB 8001. Including for such measuring instruments:
Special appointments, decisive specific tasks in a specific area;
Flow measurements in a wind tunnel
As mentioned above, the wind tunnel is used to generate reference metrological media in the measuring nozzle, and two methods are used to measure the flow velocity. In addition to basic gauges such as a standard differential pressure gauge and a Prandtl tube, the measurement system is equipped with an inverter for precise fan speed control, a stagnant tube differential pressure gauge, a microclimate meter and a thermometer to measure the air temperature in the tunnel.
Which are used in limited ranges or those in which the functionality is used in full;
Requiring certain metrological characteristics in real conditions of use.
Calibration of measuring instruments is allowed to be carried out by persons who have undergone special training and are certified in the manner prescribed by the State Standard. The frequency or interval of calibration is set by the owner according to the recommendations of the calibration laboratory. All scientific and methodological guidelines for calibration work, as well as registration of a standard calibration procedure, is carried out by BelGIM.
How to calibrate anemometers
The calibrated calibration errors and calibration uncertainty are then calculated from the uncertainty budget. A calibration certificate is issued as proof of anemometer calibration. The main group, which, depending on the version, is equipped with various additional measurement options.
Using the accreditation process, we discover customers who use anemometers in their work, which, according to the relevant regulations, must be calibrated in accredited laboratories. Initially, we equipped our laboratory with special equipment for testing conductors for testing current differential protection, since this was no longer available in Poland. Consistently improving the equipment that we tried to supplement, which official laboratories do not do. We can model voltage and current signals in varying degrees deformations both in the case of stationary and random deformations.
The control of the use of measuring instruments that have already passed the calibration process is carried out by the metrological service of business entities. The work of calibration laboratories is supervised by accreditation bodies for calibration laboratories. The bodies of the State metrological supervision supervise the assignment of measuring instruments to those subject to calibration. In addition, standards and auxiliary measuring instruments that are used during calibration are subject to the State Metrological Supervision.
The procedure for acceptance and registration of measuring instruments for calibration
We have models similar to those of official laboratories. In ten years of activity, we have issued several thousand certificates, whose form and content have changed, and now we look almost optimal. A calibration certificate, also known as a calibration certificate or calibration certificate, is a separate document assigned to one specific item. measuring device, which displays numerical tables or graphs of instrument errors for specific measurement points. This document informs the user about the metrological properties of this replica.
Calibration procedure
Calibration of measuring instruments is carried out by accredited calibration laboratories. And the procedure for accreditation is established by the State Standard.
Measuring instruments must be provided for calibration along with operational documents, and documents with established metrological characteristics may also be additionally required. Such a document may be: a verification certificate, a certificate of metrological certification, a certificate of calibration, or requirements for the metrological characteristics of a measuring instrument, set out in writing by the owner.
Our certificate consists of spreadsheets made using popular program spreadsheets. For each function of the tested meter, a separate sheet is created that contains the data: control meter, samples used, climatic conditions during the test, the parameters of the test signal and, of course, the results of comparative tests with the standard. The information given in the numerical tables is complemented by graphs, which makes it clearer. On the graphs, we see not only that the errors fall within the tolerance range, but also in which storage they fit, and whether this characteristic is more or less linear.
Calibration of measuring instruments should be carried out in accordance with standard procedures calibration, which are registered in BelGIM. It is also allowed to carry out calibration according to the method approved by the head of the calibration laboratory. Each calibration method is developed in accordance with the requirements of STB 8004.
Do tests regularly, you can quickly assess whether any tool is stable or not, which allows you to easily evaluate its quality. In the case of a responsible measurement, the accuracy of the instrument can be improved using corrections taken from the certificate, especially if the meter has been tested more than once and shows time stability. If for the same meter we only have an inspection certificate, or even an authentication certificate, which does not contain the results of a comparison with the standard, but only that the errors fall within the limits set by the manufacturer, then we must accept the limit of these errors.
Calibration takes place in the following order:
An application is being considered to determine all the technical possibilities for such a calibration, taking into account the requirements of the customer's requirements;
Methodology is being developed and, if necessary, it is agreed with the customer;
Carrying out calibration and registration of its results.
According to the study, the vast majority of meters show errors that are significantly less than the manufacturer's declaration. This is because the product specification for marginal errors must account for product scatter and long-term component changes. In addition, manufacturers with an established brand cannot afford any possible competition claims that their product does not meet the BOM specifications and "chills in the cold" that determine the accuracy of their products with a huge margin.
It so often happens that our meter is several tens of times more accurate than the specification, and we can measure it more accurately, of course, if we know - and this is what we can learn from a calibration certificate! Also with a calibration certificate, we can find out that products of unknown and low-cost brands usually do not meet the specifications indicated in the specifications, but nevertheless, subject to amendments, it can be quite measured.
Calibration results are recorded in the protocol, which is established in the methodology for its implementation. All results must be included in the calibration certificate. In the event that the results do not meet the stated requirements of the customer (they are negative), an extract from the protocol or the protocol itself is provided, which indicates the reasons for the discrepancy.
There is another very important advantage of the form of certificates created in our laboratory. Well, usually when researching a meter, we first record the results in a dirty notebook and then make the final certificate on the computer. Prescription errors often occur, many of which would escape the attention of the operator if the data were included only in numerical form in the tables. However, on a graph that is created on a regular basis using a spreadsheet, the error will be immediately visible.
Also, random errors that occur during the study will be shown on the graphs, since usually well-built meters are monotonous, not zigzag. It is also important that a certificate with detailed results impose discipline on the examiner, because if he did it wrong, this fact could always be demonstrated, and then the laboratory would immediately lose credibility. If he has documents without any results, it can be a temptation for people who irresponsibly "make things easier".
Registration of the certificate of calibration, its content and the content of all subsequent pages
The following pages of the certificate must contain:
The method for which the calibration was carried out;
List of measuring instruments and auxiliary measuring instruments that were used in the calibration, while indicating the type, metrological characteristics, serial number and date when the last metrological certification, verification was carried out;
Information about the limited or extended scope of calibration;
The points of the range in which the measurements were taken, the number of measurements taken, and, if necessary, the detailed description the stage of preparation for calibration;
The conditions under which the calibration was carried out: humidity, temperature, supply voltage, atmospheric pressure, etc.;
Algorithm for processing calibration results;
The results of calibration, measurements, which are provided in tabular, graphical or analytical form.
Each subsequent page of the calibration certificate must be issued with the content of the certificate number, date of completion, numbered pages with the signature of the person who performed the calibration.
