Abstract

The invention relates to a pressure sensor, which comprises a pressure detection unit, a mounting part and a lower box body, and is characterized in that the pressure detection unit is used for detecting the pressure of liquid; the pressure detection unit is arranged on the upper side of the mounting part, and a pressure opening used for allowing the liquid to enter and exit is formed in the position, opposite to the pressure detection unit, of the mounting part; a lower box body is connected to the lower side of the mounting part, a guide transition groove is formed in a bottom plate of the lower box body, and a liquid opening communicated with one end of the guide transition groove is further formed in the lower box body. The pressure sensor provided by the invention is used for detecting the pressure of the liquid so as to improve the detection precision.

Description

Technical field [0001] The present invention relates to the technical field of pressure detecting devices, and more particularly to a pressure sensor. Background technique [0002] In the prior art, the pressure sensor typically includes a sealing cover, a pressure port, a pressure detecting chip, and a digital-to-analog conversion chip. The pressure detecting chip and the digital-to-analog conversion chip are disposed in the sealing cover, and the pressure port is opened on the sealing cover, and is disposed opposite the pressure detecting chip to contact the sensitive surface of the liquid to detect the chip, so that the pressure detection chip acquires the liquid. pressure. In the prior art, the pressure sensor is in condensation, high humidity or nonionic liquid applications, especially for a long time during long-term operation in electron fluorinated fluid (superculed coolant), especially long-term, and has a long period of time. Tiny particulate matter, the accumulation of...
