The PR6423/000-131 is an Emerson differential expansion sensor designed to measure the thermal expansion of rotating machinery housings or enclosures. By monitoring the expansion, the operating state of the equipment can be indirectly reflected, such as overheating, wear, etc., so as to achieve early fault warning of the equipment.

Product characteristics

High precision: The use of advanced measurement technology, with high measurement accuracy.

High temperature resistance: able to work stably in harsh industrial environments for a long time.

Anti-vibration: with strong anti-vibration ability, suitable for large vibration conditions.

Easy installation: Flexible installation and easy integration into existing systems.

Various signal output: can provide a variety of types of output signals, such as analog signals, digital signals, etc., easy to connect with other devices.

Working principle

The operating principle of the differential expansion sensor is based on the physical properties of thermal expansion. When the equipment is running, due to friction heat generation and other reasons, the temperature of the bearing seat or housing will increase, resulting in thermal expansion. By measuring this tiny amount of expansion, the expansion sensor can reflect the temperature change of the equipment.

Application field

Steam turbine: Monitor the thermal expansion of the bearing housing of the steam turbine and judge the wear of the bearing.

Motor: Monitor the thermal expansion of the stator, rotor and other parts of the motor, and judge the overload of the motor.

Pump: Monitor the thermal expansion of the pump shell to determine the running state of the pump.

Compressor: Monitor the thermal expansion of the compressor housing to determine the load of the compressor.
