The STJ-SG-2HSTJ-SG-2H vibration sensor, vibration sensor and vibration monitor can be used for continuous long-term monitoring and is suitable for measurement of mechanical vibrations such as steam turbines, fans, pumps and coal mills. The working principle is based on a primary component that converts mechanical energy into electrical energy. It is fixed on the bracket by two coils, and a magnetic steel in the middle is connected to the casing through a spring, and the magnetic steel moves in the line. The magnetic lines of force are cut, thus generating an induced electromotive force. The voltage is proportional to the speed of the casing, which is called the vibration speed sensor. The vibration sensor produced by Zhengzhou Hangke has small volume, good sealing and long service life. Due to the double coil structure, it can superimpose the effective signal, and the interference signal attenuation effectively improves the anti-interference ability.

STJ-SG-2HSTJ-SG-2H vibration sensor is also called magnetoelectric vibration speed sensor, which is mainly used for vibration monitoring of power plant generator sets, fans, rotating machinery, blasting, etc. It is also widely used in pile foundation detection and oil exploration, with wide frequency band. And the higher the false frequency, the tolerance of each parameter index is within ± 5%. Good stability, high precision, rich signal acquisition, double coil structure improves resistance to common mode interference, the coil can rotate freely within 360°, effectively eliminating surface wave interference. Therefore, the sensor has high signal-to-noise ratio, small phase difference, high dynamic resolution and strong temperature adaptability, and is suitable for seismic exploration in various environments. Mainly installed on the bearing caps of various rotating machinery, such as steam turbines, compressors, fans and pumps. It is an electromagnetic sensor that cuts magnetic lines by a moving coil and outputs a voltage. Therefore, it does not need to supply power and installation capacity when working.
