HG-808A Integrated Vibration Transmitter Shear Mode Piezoelectric Panel Meters , DCS , And PLC

HG-808A Integrated Vibration Transmitter

I Brief Introduction

The integrated vibration sensor and transmitter is easy to install on the equipment to be used in conjunction with condition monitoring systems, such as panel meters, DCS, and PLC, etc. It is particularly applicable to monitor online the conditions of important machinery.

The integrated vibration transmitter integrates a shear-mode piezoelectric accelerometer with amplifier, integrator and transmitter to output the RMS value of the vibration acceleration, velocity or displacement (looped power 2-line or 3-line 4-20mA current signal).

III Wiring

IV Precautions

1) The sensor must have a close and rigid contact with the item under test, whose surface must be very smooth. The sensor is installed with lock washer.

2) The cable and connector can be pasted with a shield of silicone rubber after being tightened together to prevent them from getting loose.
