Signal Transmission Characteristics of Pressure Sensors

Signal transmission characteristics of pressure sensors

Pressure gauge characteristics of piezoelectric sensors:The range and functionality of piezoelectric sensors has been further extended, and basic and special parameters can be measured depending on the situation. At the same time, the sensitivity and measurement accuracy of piezoelectric sensors have been improved. For weak signal measurement, various signals can be corrected and compensated, and measurement data can be stored as needed. It improves the stability and possibility of data measurement, reduces the interference of the external environment on the output signal of the pressure sensor, and makes the measurement selective. It can realize self-diagnostic function, lock the fault location timely and accurately, determine the fault state quickly, and solve some problems that cannot be solved by hardware.

The choice of signal output forms and interfaces has become more diverse, and communication distances have been greatly improved. Some piezoelectric sensors use vibrators made of silicon, and thus use in the hot environments described above may reduce measurement accuracy due to heat resistance and durability. As a result, the heat resistance and durability of piezoelectric sensors have been further improved, and techniques for accurate pressure detection in thermal environments have been explored.

Existing piezoelectric sensors still exist at high temperatures, and have many problems such as low measurement accuracy, unstable installation, imperfect function, high temperature resistance not exceeding 1000 degrees Celsius, and even cannot be used. The piezoelectric sensor under high temperature conditions includes a base 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 to the left and right sides of the upper part of the base plate respectively, the mounting plate device includes a mounting plate main body, a fixing tube, a locking rod, and a locking plate, and the piezoelectric sensor fixing tubes are welded to the left and right sides of the upper part of the mounting plate main body respectively. The installation of the mining vibration sensor also requires attention.
