Dual-channel Intelligent Thermal Expansion Monitoring Protector

Introduction:

This product delivers cost-effective continuous monitoring and protection functions for large rotating machinery. It is a specially developed solution designed for continuously monitoring and protecting mechanical equipment ranging from moderately critical to low-criticality levels across multiple industrial sectors, including petrochemical, oil & gas, power generation, water treatment, pulp & paper, machining, mining, cement and other industries. It is applicable to large rotating machinery such as 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 and water turbines.
