Core Functions
Dual-channel Redundant Axial Displacement Monitoring
Two independent collections of rotor axial displacement values, mutual verification, avoiding false protection caused by single-channel failure, real-time monitoring of thrust bearing wear, axial force imbalance faults.
Multi-level Safety Interlock Protection
Pre-alarm: Axial displacement approaching the warning value, upper-level sound and light alarm reminder for operation and maintenance inspection
Hazard Shutdown Interlock: Over-limit displacement triggers emergency shutdown of the unit, protecting turbine thrust pads and rotor from damage
Sensor Breakline Fault Alarm: Abnormal probe line directly alarms, eliminating the risk of protection failure
Data Recording and Traceability
Analog signal connection to DCS for historical trend storage, can analyze the axial force change laws during unit start-stop, load variation processes.
Peak Holding, Alarm First Out Memory Function
Lock in the maximum axial displacement peak, record the first triggered alarm fault point, facilitating post-fault traceability analysis.

Typical Application Scenarios
Power Plant, Gas Turbine, Turbine Generator Set TSI Safety Monitoring System
Axial Displacement Protection for Large Reciprocating, Centrifugal Process Compressors
Refinery, Chemical, Self-owned Power Plant Rotating Machinery Unit Safety Interlock Protection
