Multifunctional Status Monitoring Protection Device
Product Description
Rotating manchinery monitoring protection device uses brand new digital processing technology, and is one module-type combined multifunctional meter with high rediability. It consists of rotational speed, axial displacement, differential expansion, shaft vibration, thermal expansion, sevo motor, tank fuel level, three-out of two voting module and other modules. It provides various paremeter measurements for safe running and warning of early failures. It is widely used in electrial power, machinery, petroleum, chemical and metallurgy. It has following features" easy mounting and maintenace, simple operation, high reliability and strong anti-interfearence ability.
