What you need to know about pressure equipment calibration

Calibration of pressure equipment or any device, sensor in industrial production is equally necessary. Calibration is like checking to make sure your devices are always operating at their maximum capacity without overload for the best product quality. So what is calibration and what pressure calibrators are there?

What is Pressure Equipment Calibration?

Calibration of pressure equipment or calibration is the activity of comparing the value of a quantity expressed by a measuring instrument with the equivalent value expressed by a measurement standard. This is the process used to determine the errors, "deviations" of the measuring equipment from the rated values ​​according to the standard.

Calibration of pressure equipment is practically, not only a voluntary activity anymore, but for large business units, producing on high-tech lines with hazardous chemical and petrochemical products. endangering human life, this is a regular and closely monitored activity.

Pressure Equipment Calibration Devices

Calibration of pressure equipment has a number of commonly used devices such as: spring manometer, piston manometer, liquid manometer, composite manometer, electrical principle manometer.

Pressure Calibrator is a spring-type manometer with a fairly simple operating principle. It relies on the elastic deformation of the spring element under the action of pressure to turn the clock hands. Distortion is usually magnified by magnifying actuators and can be converted to a long-distance signal.

Calibration device of pressure equipment is a piston type manometer with direct load operation principle. That is, the measured pressure is compared with the weight pressure exerted by the piston and the weight on the cross-section of that piston.

Instrument Calibration of pressure equipment is an electric manometer based on the change in electrical properties of materials under the action of pressure. This manometer is based on the change of resistance called a resistance manometer or by the name of the type of conductor (resistive maganin manometer, electric manometer, sercer salt, turbine, quartz...).

Calibrators of pressure equipment are liquid manometers, or combinations, which are quite rare. The fluid type has the following operating principle. The measured pressure is compared with the pressure of the liquid column of the corresponding height (U-shaped pressure, vacuum pressure, tank manometer, mercury manometer, etc.). Calibration of pressure equipment is a composite manometer that uses a combination of different principles such as mechanical and electrical principles.

Calibration of pressure equipment is a necessary work in the production of products, it has many different means and equipment to carry out this work.
