WZ-3C  is an intelligent speed monitoring and protection instrument with arm as the core. The monitoring instrument has the following functions: speed monitoring, double alarm set point, analog current output, etc. It is suitable for the monitoring and protection of rotating machinery speed in power, petroleum, chemical and other industrial sectors.

 

 

Function description

 

1. The measured value and alarm setting value can be displayed on the LED nixie tube respectively.

 

2. When the alarm setting value is exceeded, the alarm indicator lights up on the rear panel, and the output switch protects the monitored equipment. The alarm setting delay is adjusted, ranging from 1 to 60 seconds, to prevent false alarm caused by field interference.

 

3. With current output interface, it can be connected with computer, DCS, PLC system, paperless recorder and other equipment.

 

4. It has the function of power on and power-off detection, and can cut off the output circuit of alarm and shutdown at the same time, so as to effectively inhibit the false alarm of the instrument.
