HZD-B-9A/F/X/S/I vibration transmitter is used together with ST series speed sensor

1. Introduction

   The vibration transmitter is used in conjunction with the ST series speed sensor, and is mainly used to detect the juedui vibration of the rotating machinery, such as the vibration of the casing, the vibration of the bearing bush, the mechanical vibration, etc.; to monitor the rotor due to imbalance, misalignment, loose parts, and rolling bearing damage. , gear damage caused by vibration changes. It is suitable for large rotating machinery such as steam turbines, water turbines, fans, compressors, oxygen generators, motors, pumps, gearboxes, etc., especially suitable for the transformation of old units.

ST series magnetoelectric speed sensors can measure various displacements and speeds after matching with vibration and intensity gauges. The vibration of the rotor supported by rolling bearings will be sufficiently large to be transmitted to the bearing seat. The speed sensor installed on the bearing seat or very close to the bearing shell will cut the magnetic field line by the internal moving coil to output voltage, and provide signals to the monitoring instrument. It is used to predict and alarm mechanical failures.
