Product Description
WQB Type Crankpin Oil Temp.Monitoring And Alarm Device
Product Introduction:
WQB type crankpin oil temperature monitoring and alarm device mainly consists of temperature sensor and alarm control box. The product design meets requirements of rules. It has the characteristics of reasonable configuration, high precision, good stability, safety and reliability etc. matching with PA, PC type diesel engine, the device can monitor real-time running temperature of crankpin, intelligent analysis and judgment of crankpin’s working condition, and alarm failure of each diesel cylinder timely. When emergent failure occurs, the device will send out stop signal to avoid accident.
