Abstract

The invention discloses a pressure transmitter measuring device. The device comprises a fixed seat. Vertical plates are fixedly arranged on the two sides of the top end of the fixing base. Sliding grooves are formed in the middles of one sides of the two vertical plates. The two sides of the inner walls of the two sliding grooves are slidably connected with the two sides of the two sliding blockscorrespondingly. One sides of the two sliding blocks are fixedly connected with the middles of the two sides of the supporting plate correspondingly. According to the pressure transmitter measuring device, a sleeve is arranged, the sleeve slides to be connected with the circular groove in a clamping manner. The sleeve extrudes a circular plate, and the circular plate compresses a spring. Under thecounter-acting force of the spring, the rubber pad on the circular plate is tightly attached to the sleeve, so as to keep airtightness of the junction of the sleeve and the circular groove. The coverplate is in threaded connection with the sleeve, so that the sealing performance of the top end of the sleeve is kept. The sealing performance between the detection port and the pressure transmitterbody can be kept, gas leakage at the joint is avoided, and the accuracy of data detected by the pressure transmitter body is kept.

Description

technical field [0001] The invention relates to a pressure transmitter, in particular to a pressure transmitter measuring device. Background technique [0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into standard electrical signals, which can be supplied to secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement, indication and process adjustment. [0003] In view of this, Chinese Patent No. CN208568161U proposes a pressure transmitter measuring device, which realizes rapid detection of the quality of the pressure transmitter and ensures the accuracy of the detection data when the pressure transmitter is used. Chinese Patent No. CN208520519U proposes a pressure transmitter transmitter and pressure measurement system, the above-mentioned pa...
