Preferably, in the second step, the size of the pressure sensor mounting hole is consistent, even if the pressure sensor mounting hole is correctly mounted, the threaded part of the pressure sensor mounting hole is abraded, so that the air tightness is not ideal, the performance of the pressure sensor is lost, and a safety hazard is caused.
Preferably, the overload range of the pressure sensor is 150% of the maximum range, so that the pressure to be measured is within the measuring range, and the optimal range of the selected sensor is 2 times of the measured pressure, thus ensuring the normal output of the sensor even if the pressure is suddenly increased.
Preferably, the application indexes of the pressure sensor can not meet the waterproof requirement, and the circuit part inside the pressure sensor is protected to avoid long-time operation in a humid environment, so that the water in the water cooling device of the production equipment can not leak, and the product with better waterproof performance is obtained.
