Speed monitoring device

Overview

The HZS-04 intelligent tachometer is an intelligent speed monitoring and protection instrument with ARM as the core. This monitoring instrument has functions such as speed monitoring, dual alarm set points, and analog current output. Suitable for monitoring and protecting the rotational speed of rotating machinery in industrial sectors such as power, petroleum, and chemical.

• Sensor signal input

Sensor input method for intelligent tachometer:Magnetic resistance sensor, Hall sensor or eddy current sensor

Number of teeth on the speed measuring disc gear: 1~120 teeth

• Overspeed protection and speed alarm

The intelligent tachometer is equipped with two speed alarm limit values. As long as the measured speed exceeds the set alarm value or danger value, the alarm indicator light or danger indicator light on the front panel will light up, and the alarm relay or danger relay will act, outputting a switch signal. The alarm response time is0.1S.
