a high pressure transmitter

Abstract

The invention discloses a high pressure transmitter. The high pressure transmitter comprises a stainless steel housing, a pressure diaphragm, a pressure sensing probe, a pressure sensitive member, a pressure acquiring connector and a digital displayer. A front cover is fixed on the front end of the stainless steel housing through a fixing bolt. A digital displayer is installed on the front end of the stainless steel housing. The digital displayer is connected to a chip set. A rear cover is welded on the rear end of the stainless steel housing through laser cold welding technology. The chip set is installed inside the bottom end of the stainless steel housing. The bottom end of the chip set is connected to an alloy aviation plug which is connected to an electronic circuit board. The electronic circuit board is installed in the voltage taking connector. The high voltage transmitter is compact in structure, good in tightness, stable and reliable in connection. The pressure sensing probe can measure the pressure of a viscous liquid and a liquid level; a pressure sensing elastic member and a pressure-guiding hole realize pressure sensing in a wide range and solve problems of deposition and obstruction in a threaded rod and the pressure sensing probe. The high voltage transmitter is clean and convenient. A thickened diaphragm made of stainless steel or a tantalum material can resist quadruple pressure and realize high pressure measurement.

Description

technical field [0001] The invention relates to the technical field of liquid level detection, in particular to a high-voltage transmitter. Background technique [0002] In the production equipment of fiber, rubber, plastic and other products, it is usually necessary to use pressure transmitters to measure the viscous fluid pressure, including differential pressure, absolute pressure and surface pressure, so as to monitor and control the parameters of the production process. Control to keep it within the safe production range. During the manufacturing process of the current pressure transmitter, the sealing performance is poor, the structural connection is poor, and the pressure diaphragm can withstand a low pressure value. When the full scale is reached, the pressure transmitter will be destroyed. It is expensive to maintain and calibrate, and seriously affects the production of fiber, rubber, plastic and other products. Contents of the invention [0003] The purpose of...
