Bently Nevada 991-25-70-01-05 Thrust Position Transmitter – 3300 Series Machinery Protection System
When a critical rotating machine loses its axial position monitoring, the consequences are immediate and catastrophic: undetected rotor thrust can destroy turbine bearings, collapse compressor stages, and trigger unplanned shutdowns that cost tens of thousands of dollars per hour. In high-stakes industries like oil & gas, power generation, and petrochemicals, there is no acceptable margin for error in thrust measurement — and that is precisely why the Bently Nevada 991-25-70-01-05 Thrust Transmitter exists.
The 991-25-70-01-05 is a precision thrust position transmitter within Bently Nevada’s globally trusted 3300 Series Machinery Protection System. Engineered for continuous, real-time axial displacement monitoring of rotating shafts, this transmitter converts eddy-current proximity probe signals into industry-standard 4–20 mA outputs compatible with DCS, PLC, and safety instrumented systems (SIS). Its position in the 3300 Series lineup makes it one of the most widely deployed thrust monitoring solutions across refineries, power plants, and LNG facilities worldwide.
