Sales of pressure calibrators

Pressure calibrators are used to test the accuracy of the values ​​of the pressure display or pressure gauge as well as the output of pressure transmitters and pressure differences and have a relatively large variety.

Dead white tester or dead weight tester : Using precisely defined weights and applying pressure to the hydraulic fluid, the dead weight tester provides a completely reliable and accurate calibration method. Due to the measurable pressure that is applied to the pressure gauge through the weights, it will be easy to check the pressure gauge values. Death Whitestresser pressure calibrators are offered in various ranges up to 1000 times or more, and depending on the manufacturer, prices can reach up to about 7 or 8 thousand dollars.

Hand Pump Calibrator  : Designed for portable pressure measurement with considerable reliability with ease and covers a wide range from negative up to 1000 bar pressure. Indian pressure calibrators The pump is designed to be pneumatic and hydraulic depending on the range, and hydraulic pressure calibrators are sometimes possible with distilled water.
Accuracy of manual pressure calibrator or hand pump, depending on the test gauge or reference barometer connected to it, can be accurate or accurate up to one hundredth of full scale. Hand pump calibrators are usually provided with a carrying case and adapters for connecting a variety of pressure gauges and pressure transmitters, as well as hoses that can withstand up to 700 bar in hydraulic cases.

Electronic desktop pressure calibrators: Laboratory pressure calibrators that are used with very high accuracy to measure low range pressures of equipment such as pressure gauges and pressure transmitters and pressure differences. Some of these equipments with six digits and very high accuracy are the best way to measure the pressure accuracy of equipments such as low range pressure transmitters. Has. Also, in advanced desktop and laboratory pressure calibrators, it is possible to measure and make the milliampere output of the transmitter and convert this milliampere to pressure, or vice versa, it is possible to make the pressure appropriate to the output of a transmitter, ie both pressure source and current source. They can be used to accurately measure signal current.

Portable and compact pressure calibrators: These pressure calibrators are a kind of integration of caliper hand pump and electronic laboratory calibrators and take advantage of both facilities..

Pressure comparator or comparator: A pressure comparator is used to compare an accurate pressure gauge or test gauge with the pressure gauge tested. In practice, the mechanism and operation of the compressor is similar to the Indian calibrator pump, except that it is usually on the table and can be used for high pressures. The actual accuracy of the comparator depends on the gauge test.
