Vibration Sensor for Hydrogen generator
In general, vibration sensors have only relative and inertial principles in terms of mechanical receiving principle, but in terms of electromechanical conversion, due to their different methods and properties, they have a wide range of applications and a wide range of applications.
The sensor used in modern vibration measurement is not a traditional conceptually independent mechanical measuring device. It is only a part of the entire measurement system and is closely related to the subsequent electronic circuits.
Due to the different internal electromechanical transformation principle of the sensor, the output power is also different. Some change the change in the mechanical quantity into the electromotive force and the change in the charge, while others convert the change in the mechanical vibration quantity into the change in the electrical parameter such as a resistance and an inductance. In general, these power levels cannot be directly accepted by subsequent display, recording, and analysis instruments. Therefore, sensors for different electromechanical conversion principles must be accompanied by dedicated measurement lines. The function of the measuring circuit is to change the output power of the sensor to a general voltage signal which can be accepted by the analysis instrument in the subsequent display. Therefore, vibration sensors can have the following classification methods according to their functions:
According to the principle of mechanical reception: relative, inertia;
According to electromechanical conversion principle: electric, piezoelectric, eddy current, inductive, capacitive, resistive, photoelectric;
According to the measured mechanical quantity: displacement sensor, speed sensor, acceleration sensor, force sensor, strain sensor, torsional vibration sensor, torque sensor.
