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.
