LH6052 Intelligent Speed Monitoring and Protection Instrument

I. Overview

The intelligent tachometer adoptsARMIntelligent speed monitoring and protection instrument as the core. This monitoring instrument has functions such as speed measurement, two-level alarm, overspeed protection, analog current output, and sensor fault monitoring. Suitable for monitoring and protecting the rotational speed of rotating machinery in industrial sectors such as power, textile, petroleum, and chemical. For example, monitoring and protecting the rotational speed of rotating machinery such as steam turbines, water pumps, fans, motors, compressors, etc.

2、 Input signal:

Magnetic reluctance speed sensor or Hall speed sensor

Waveform: sine wave or square wave pulse signal

3、 Function Description:

The measured value and alarm set value can be separately set atLEDDisplayed on the digital tube.

Alarm values can be freely set and modified.

When the alarm setting value is exceeded, the alarm indicator light will turn on, and at the same time, a switch signal will be output on the rear panel to protect the monitored equipment.

Alarm setting delay adjustment, range1-60Second, to prevent on-site interference from causing false alarms.

Maintain set parameters and other memory values during power outages.

Equipped with a current output interface, it can be connected to computersDCSThePLCConnect devices such as systems and paperless recorders.
