Dual-channel Intelligent Rotational Speed Monitoring Protector

This product delivers cost-effective continuous monitoring and protection functions for large rotating machinery. It is a specially designed and developed solution for continuous monitoring and protection of mechanical equipment ranging from moderately critical to low-critical levels across multiple industrial sectors, and is applicable to petrochemical, oil & gas, power generation, water treatment, pulp & paper, machining, mining, cement and other industries. It covers large rotating machinery including large feed water pumps, chemical process pumps, large cooling tower fans, tunnel ventilators, blowers, induced draft fans, coal mills, centrifuges, mixers, large agitators, turbo compressors, reciprocating compressors, drive motors, generators, water turbines, etc.

## Technical Specifications

3.5-inch touch screen with human-machine interface

Dual-channel rotational speed measurement display with a resolution accuracy of ±1 RPM; proportional progress bar display with a resolution accuracy of 1%, and a maximum measuring range of 65,000 RPM

Maximum rotational speed value memory function

Capable of monitoring zero speed of rotating machinery and outputting zero-speed alarm signals

Rotational speed sensor input (supporting eddy current, Hall effect and magnetoresistive rotational speed sensors); real-time monitoring and display of sensor gap voltage

2 channels of analog output (4~20mA output by default, with optional 2-10V output)
