The XJZC-03A/QF speed impactor monitor receives two emergency trip signals while measuring the speed. Used for continuous monitoring and measurement of the rotational speed of rotating mechanical devices, while recording two emergency shutdown speeds; The output analog current signal and alarm contact signal can be easily connected to DCS, PLC systems, and paperless recorders. It can be widely used in industries such as electricity, wind turbines, steel, and petrochemicals.

The XJZC-03A/QF speed impactor monitoring device receives two on-site impactor switch signals. When the switch is closed, it indicates the impactor's output status signal, and when it is open, it indicates the impactor's non output status signal. It can also receive two high-level signals.

Technical parameters of XJZC-03A/QF speed impactor monitoring instrument:
