The vibration sensor ZHJ-2 is a passive magnetoelectric vibration sensor. Its working principle is to use a moving coil to cut the magnetic lines of force to output a sinusoidal voltage signal. This sensor has a simple structure and stable performance, and can accurately monitor the vibration of rotating machinery.

The vibration sensor ZHJ-2 is equipped with the HN-2 dual-channel vibration monitor to monitor the vibration of the casing or bearing of the rotating machinery. By monitoring the vibration velocity value and vibration amplitude, the operating status of the equipment can be effectively judged, equipment failure can be prevented, and production efficiency can be improved.

The vibration sensor ZHJ-2 uses the coil to make relative motion in the magnetic field to cut the magnetic lines of force and generate a voltage signal proportional to the vibration velocity. Vibration velocity, displacement and acceleration can be measured through amplification and calculus operations. Magnetoelectric sensors have the advantages of high sensitivity and low internal resistance, which makes them widely used in the field of mechanical vibration testing.

Compared with other types of vibration sensors, ZHJ-2 has the following advantages:

1. High sensitivity: The magnetoelectric sensor has high sensitivity and can accurately sense tiny vibration changes, thus providing users with accurate vibration data.

2. Low internal resistance: The internal resistance of the vibration sensor ZHJ-2 is low, which is conducive to the transmission and amplification of the signal, ensuring the accuracy of the vibration data.

3. Strong stability: The passive magnetoelectric design makes it highly stable in long-term work and can adapt to various harsh environments.

4. Easy to install and maintain: The vibration sensor has a simple structure, easy installation, low maintenance cost, and is suitable for use in various industrial occasions.

5. Wide application: The vibration sensor can be applied to vibration monitoring of various rotating machinery, such as fans, compressors, pumps, etc., with high versatility.

In short, the vibration sensor ZHJ-2 has become an ideal choice for vibration monitoring of rotating machinery with its high precision, high stability, ease of use and wide applicability. With the increasing requirements of modern industrial production for equipment stability and production efficiency, the application of ZHJ-2 in the field of vibration monitoring will become more and more extensive.
