The 991-06-70-01-CN is a loop-powered thrust transmitter used for axial displacement monitoring in rotating machinery. It converts proximity probe signals into a stable 4–20 mA output for integration into industrial automation and protection systems.
This model is widely used in turbines, compressors, pumps, and other rotating equipment where axial shaft position must be continuously monitored to ensure mechanical stability and prevent thrust-related failures.
The 991 series is specifically engineered for thrust monitoring applications rather than radial vibration, making it essential for compressor and turbine systems where axial load control directly affects operational safety and equipment reliability.
The CN variant is generally associated with region-specific certification and deployment configurations for industrial compliance requirements.
The Bently Nevada 991-06-70-01-CN 991 Thrust Sensor Module is designed for axial displacement (thrust position) monitoring in rotating machinery, delivering stable 4–20 mA output for industrial protection and condition monitoring systems.
Typical applications include:
Steam turbine thrust bearing position monitoring
