Problems solved by technology

Since the pressure sensor is an electronic component, there is a limit on the use of temperature. When the temperature is too high, the pressure sensor will be destroyed, resulting in abnormal fluctuations in measurement data, reduced accuracy, and even loss of measurement function in severe cases.

Abstract

The present invention discloses an overheating protective device of a pressure sensor. The objective of the invention is to prevent a pressure sensor from overheating when the pressure sensor measuresa voltage of a medium. The overheating protective device comprises a pedestal, a hinged pipe joint and a radiating tube. The pedestal is connected with the pressure sensor; the hinged pipe joint is connected with a medium; one end of the radiating tube is communicated with one side of the pedestal, and the other end of the radiating tube is communicated with the hinged pipe joint, wherein the hinged pipe joint transmits the pressure of the medium to the pressure sensor through the radiating tube and the pedestal, and the radiating tube is configured to perform heat radiation and cooling of the pressure of the medium. The overheating protective device of a pressure sensor can play an efficient overheating protection effect on the pressure senor, prolongs a service life and ensures work reliability, and measurement data is more accurate.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to an overheat protection device for a pressure sensor. Background technique [0002] Because the pressure sensor can quickly measure the pressure of the medium and feed back the pressure data in real time, and has the advantages of simple, fast and accurate measurement, it is widely used in electrical appliances, machinery, industry and other fields. [0003] The traditional installation method of the pressure sensor is: directly tap the threaded hole on the medium transportation pipeline, and then install the pressure sensor directly into the threaded hole. The distance between the sensor and the measurement medium transportation pipeline is very close. When the measured medium is a high-temperature fluid , the high temperature of the fluid will be directly transmitted to the pressure sensor. Since the pressure sensor is an electronic component, there is a limit on the tempe...
