Mass Calibration

November 3, 2021

The masses are measurement standards that materialize the kg, which is the unit of measurement of the International System of Units (SI). The masses have been used for centuries in commercial and commercial operations and are currently widely used for the calibration and verification of weighing instruments.

Calibration consists of comparing the values ​​indicated by the instrument to be calibrated with the values ​​of the standard masses used, under specified conditions and with a defined method, which takes into account the influence of different factors that affect the reading of the equipment to be calibrated. Calibration is carried out in a controlled and documented way.

It makes it possible to ensure the reliability of the measurements of the calibrated equipment, and to guarantee proper operation in the facilities and processes where they are used, helping to increase quality. The result of the calibration is collected in a Calibration Certificate, where the correction values ​​to be applied at different calibration points considered will be indicated, as well as the uncertainty of said measurements.

The calibration of measuring instruments and especially the Calibrate masses is to compare the measurement of a reference standard mass with the measurement materialized by another mass. Mass calibration is carried out by comparison as long as there is a nominal equivalent standard.

Mass comparators are the instruments used to carry out this type of calibration. In this way, a direct measurement of the value of the mass to be calibrated is not made, but differential measurements are made between one mass and another.

The object of calibration is the indication provided by the instrument in response to an applied load. The results are expressed in units of mass. The value of the load indicated by the weighing instrument is affected by the force due to gravity, the temperature and density of the load, and the temperature and density of the ambient air.

The measurement uncertainty depends significantly on the properties of the weighing instrument itself to be calibrated, not only on the calibration laboratory equipment; This can be reduced to some extent by increasing the number of measurements performed for calibration.

Calibration consists of:

  1. applying test loads to the instrument to weigh under specified conditions.
  2. the determination of the error or variation of the indication.
  3. the estimation of the measurement uncertainty to be attributed to the results.
In today’s competitive marketplace, the calibration of measuring instruments is becoming increasingly important. The increasing implementation of quality systems is just one of the many reasons to calibrate equipment and systems. Specifically, pressure and vacuum metrology has always played a very relevant role in the entire spectrum of industrial, aerospace and automotive applications and in the vast majority of services available today.

It is important to maintain environmental stability during the calibration process. The requirements for stability in temperature apply to the space occupied by the standards and the measuring equipment, so that the greater the stability of the environment, the greater the reliability of the results.

Each metrological test is done at different levels based on scope. Once any test has started, it cannot be suspended and resumed later, nor can zero adjustments be made in the middle of the tests. Before taking the first reading, it is recommended to adjust to zero, but once the test has started, this adjustment will no longer be performed.

Balance Calibration

The objective of the calibration of a scale or balance has the purpose of determining the measurement error of the equipment in question, this measurement error also known as measurement uncertainty can be different in each of the measurement points, the calibration of a Scale or balance should not be understood as the repair of the same, this service aims to provide reliable information about the errors that the instrument presents so that you or your company can make decisions and can find areas of opportunity in your production processes.

The correct measurement of any body or object is very important to have a calibration laboratory that performs the calibration of scales in your company, it will guarantee safety, quality in your products or services and save you great losses in your production environment, have a certificate Calibration of your scales and balances will allow you to make smart decisions to increase your productivity and improve the quality of your finished product.

The calibration of these non-automatic weighing instruments is an activity that should be understood as a comparison made with a reference standard and a weighing instrument in order to obtain an associated uncertainty, which will be expressed in a calibration report. of each of your instruments, also known as a calibration certificate, the scale calibration is a service performed by a highly trained engineer in the calibration of non-automatic weighing instruments.

3 fundamental tests for scale calibration

  • Accuracy test.
  • Eccentricity test.
  • Respectability.

The accuracy test is generally the busiest for the calibration of scales and balances, this test is performed by our staff to determine or obtain the error that the instrument in question has at different points in its maximum range.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
