The HD-ST-A3-B3 vibration speed sensor is mainly installed on the bearing covers of various rotating mechanical devices (such as steam turbines, compressors, fans, and pumps). It is an electromagnetic sensor that cuts magnetic lines of force by a moving coil and outputs a voltage. Therefore, it has the characteristics of no need for power supply during operation and easy installation. Installation position: vertically or horizontally mounted on the vibration point to be measured, with M10 at the bottom of the sensor × 1.5 Screw fixations.
