VS-2.VS-3 magnetoelectric vibration speed sensor

The VS-2.VS-3 magneto-electric vibration speed sensor is 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 require power supply during operation and is easy to install.

Second, the basic principles

The basic principle of the CD-21 series speed sensor is based on an inertial mass (coil assembly) and a housing in which a magnet is fixed. When the inertial mass is suspended from the housing by the elastic element, the sensor housing is fixed to the vibrating body. Above, this

Vibration speed sensors are typically used to measure bearing vibration and, in rare cases, to measure shaft vibration. When measuring the vibration speed, if the sensor is installed incorrectly or the installation is not strong, the measurement result may be distorted or the sensor may be damaged due to vibration. Therefore, we must carefully choose the installation method of the vibration speed sensor. VS-2.VS-3 Magnetoelectric Vibration Speed ​​Sensor The vibration sensor is used together with the vibration monitor to achieve 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 piece of magnetic steel is connected to the casing through the piece, 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 signals, and the interference signal attenuation effectively improves the anti-interference ability.
