Abstract

The invention discloses a pressure sensor calibration device, and relates to the technical field of the pressure sensor. The pressure sensor calibration device comprises a base and a hydraulic outputdevice; a motor and a lead screw are arranged in the base, and a transmission gear is sleeved at the outside of one end of the lead screw; the hydraulic output device comprises a hydraulic cylinder, apiston and hydraulic oil; the piston and the hydraulic oil are located in the hydraulic cylinder, a thread groove is formed at the other end of the piston, one side of the top end of the hydraulic cylinder is fixedly connected with a mainstream pipe, one end of the mainstream pipe is fixedly connected with a T-joint, one end of the T-joint is fixedly connected with a first shunt. Through the pressure sensor calibration device disclosed by the invention, the pressure sensor is calibrated by using the hydraulic principle by arranging the hydraulic output device, the precision of the calibrationis improved; by arranging the measurement device, one the one hand, the phenomenon that the pressure sensor is damaged due to excessive pressure is avoided, on the other hand, the calibration operation is performed on the pressure sensor.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a pressure sensor calibration device. Background technique [0002] Pressure sensor is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools , pipelines and many other industries, the following briefly introduces the principles and applications of some commonly used sensors, as well as medical pressure sensors. Equipment calibration refers to the behavior of testing and adjusting measuring equipment or standard parts to understand their accuracy. [0003] Due to the frequent use of pressure sensors in the test, the measured values ​​of some pressure sensors are inaccurate or damaged. Durin...
