ST-2FB ST-3FB explosion-proof vibration speed sensor, vibration sensor and vibration monitor can be used for continuous long-term monitoring. It 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.

ST-2FB ST-3FB explosion-proof vibration speed sensor resolution, temperature adaptability, 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 during operation, and the explosion-proof vibration speed sensor is an inertial sensor. The vibration signal is converted into an electrical signal by the principle of magnetoelectric induction. . It is mainly composed of magnetic circuit system, inertial mass, spring damping and other parts. A magnet is rigidly fixed to the sensor, and the inertial mass (coil assembly) is suspended by a spring element. During operation, the sensor is mounted on the machine. When the machine vibrates, within the operating frequency range of the sensor, the coil and the magnet move relative to each other, and the magnetic field line is cut, and an induced voltage is generated in the coil, and the voltage value is proportional to the vibration speed value. When matched with the secondary instrument, the vibration velocity or displacement amount can be displayed mainly for mechanical vibration measurement. It uses the principle of magnetic induction to convert the vibration velocity into a voltage output. The rotor supported by the roller, the vibration will be transmitted to the bearing seat large enough, the sensor mounted on the seat or very close to the casing, the magnetic wire is cut by the internal moving coil to output the voltage, and the signal is sent to the detecting instrument for the mechanical Faults are predicted and alarmed.
