The invention provides a pressure sensor suitable for high temperature conditions and its application method, so as to solve many problems of the existing pressure sensor under high temperature conditions, such as low measurement accuracy, unstable installation, imperfect function and so on, and even can not be used.

The pressure sensor suitable for high temperature conditions comprises a bottom plate, a support plate, a thermal reaction plate, an adjustable measuring plate device, a mounting plate device and a connecting wire. The support plate is welded on the upper left and right sides of the bottom plate respectively, the thermal reaction plate is installed on the inner upper part of the support plate, and the adjustable measuring plate device is installed on the inner lower part of the support plate, The mounting plate device is respectively welded on the left and right sides of the lower part of the bottom plate, the connecting line is installed on the left part of the front surface of the adjustable measuring plate device, the mounting plate device comprises a mounting plate body, a fixed pipe, a locking rod and a locking plate, and the fixed pipe is respectively welded on the left and right sides of the upper part of the mounting plate body, One end of the locking rod is inserted into the inner upper part of the fixed pipe, and the other end is respectively welded on the left and right sides of the lower part of the locking plate.

When in use, first use the bolt to penetrate the through hole and connect the threaded hole with the thread, install the pressure sensor suitable for high temperature conditions, increase the friction between the grinding plate and the mounting surface, lock the bolt through the locking spring, and then adjust the measurement accuracy of the pressure sensor suitable for high temperature conditions by adjusting the bolt. When the thermal reaction plate is under pressure, The measurement is carried out through the adjustable measuring plate device. When the thermal reaction plate is heated and bent, the measurement is carried out through the inner side of the adjustable measuring plate device.

1. The setting of the measuring plate body is conducive to improving the measurement accuracy of the pressure sensor and solving the problem of low measurement accuracy of the pressure sensor.

3. The setting of the thermal reaction plate is conducive to enable the pressure sensor to measure both the physical pressure and the air pressure caused by heat, and solves the problem of imperfect function of the pressure sensor.

5. The setting of the adjusting bolt is conducive to facilitate the adjustment of the measurement accuracy of the pressure sensor and further improve the measurement accuracy of the pressure sensor.
