Thông số kỹ thuật của Bộ chuyển đổi tín hiệu rung HZD-B-9

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

1. Introduction

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

After the ST series magnetoelectric speed sensor is connected with the vibration and intensity meter, it can measure various displacements, speeds, etc. The vibration of the rotor supported by the rolling bearing will be transmitted to the bearing seat enough. The speed sensor installed on the bearing seat or very close to the bearing shell will output the voltage by cutting the magnetic field line by the internal moving coil, and provide the signal to the monitoring instrument. Used to predict and alarm mechanical failures.

3. Electrical indicators:
