I. Overview

HZS-04F-1G-SFWall mounted intelligent tachometerIt is an intelligent speed monitoring and protection instrument with a microcontroller as its core. This monitoring instrument has functions such as speed monitoring, forward and reverse rotation 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.

lSensor signal input

Sensor input mode of intelligent speed monitoring and protection device: forward and reverse rotationNPNCollector open circuit Hall sensor

Number of teeth on the speed measuring disc gear:1~255tooth

lOverspeed protection and speed alarm

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

lReverse alarm

When the speed dial gear reverses, the reverse indicator light will turn on, and the reverse alarm relay will activate, outputting a switch signal.

lcurrent output

Compared to measuring speed, intelligent tachometer4~20mAAnalog output, corresponding to a speed of05000rpm.(Note:5000 rpmFor factory settings, users can set this parameter as needed)

Note: If there are any special circumstances, the full capacity value should be specified at the time of ordering.
