Abstract

The present invention provides a handheld automatic pressure calibrator. The calibrator comprises a housing and an air passage member and a circuit member which are arranged in the housing, the air passage member includes a pressure source capable of supplying pressure gas, and the air passage member, the circuit member and the pressure source are integrally assembled in the housing and are integrally assembled into a shape suitable for holding by hands. The handheld automatic pressure calibrator can fully realize all the functions of pressure generation, pressure control, pressure meter connection, pressure calibration process record, operation result and report output, and is suitable for checking on-site online pressure meters.

Description

technical field [0001] The invention belongs to the field of measurement and calibration of pressure instruments and meters, and relates to a small hand-held full-automatic pressure calibrator that can automatically compress air to generate pressure gas and automatically complete gas pressure control. It can be used in the field by replacing the standard pressure module. Calibration and verification of pressure instruments with various accuracy and range. Background technique [0002] The pressure gauges used in industrial production, pressure measurement and other fields need to be calibrated regularly to ensure the accuracy of pressure gauge detection pressure and to ensure that the pressure equipment is used within a safe range. [0003] With the rapid development of industrial automation, the pressure instruments in the production process are gradually changing to digital and electrical. The installation of many pressure instruments involves sealing issues. Usually, pre...
