Speed monitoring device

I. Overview

SZC-04Intelligent rotation speedThe table is an intelligent speed monitoring and protection instrument with a microcontroller as its 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: reluctance speed sensor

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

• Overspeed 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.

• current output

Compared to measuring speed, the intelligent tachometer ranges from 4 to 20mAAnalog output, corresponding to a speed of 0-3000r/min.

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