WB-8521C relative expansion monitor is an ideal instrument for measuring the relative expansion of rotating machinery, which is used together with eddy current sensor.

WB-8521C relative expansion monitor can be widely used in the measurement and protection control of relative expansion of steam turbine, motor, aeroengine, petroleum, chemical and other departments.

Application Introduction:

Fault monitoring:

Monitor the relative expansion of rotating machinery.

Measurement parameters:

The relative expansion of the rotor relative to the bearing shell.

Unit type:

Monitoring of various rotating machines. Such as steam turbine, fan, compressor, motor, pump, etc.

Installation requirements:

For units with existing eddy current probe system, it is only necessary to connect the wires and set alarm and danger points.
