Real-World Problem Solving

Challenge: Unplanned downtime from bearing failures costs manufacturers thousands per hour. Traditional time-based maintenance either wastes resources or misses critical issues.

Solution: The 21504-00-68-10-02 enables condition-based monitoring by continuously measuring shaft position, radial vibration, and axial thrust. Early detection of bearing wear, misalignment, or rotor rubs allows scheduled maintenance before catastrophic failure occurs.

Industry Applications

Power Generation: Steam and gas turbine monitoring, generator bearing surveillance, balance-of-plant rotating equipment
Oil & Gas: Compressor trains, pipeline pumps, offshore platform machinery
Chemical Processing: Reactor agitators, centrifugal separators, high-speed mixers
Mining: Crusher drives, conveyor systems, grinding mills
Manufacturing: Paper machine rolls, printing presses, industrial fans

Integration Benefits

This proximitor seamlessly interfaces with existing Bently Nevada 8mm proximity probes and extension cables. The standardized -2 to -18 VDC output connects directly to most industrial control systems without signal conditioning. Built-in OK/Alert LED indicators provide at-a-glance system health status, while buffered outputs allow parallel connection to multiple monitoring devices.
