Maintenance Specialist Overview
The Bently Nevada 21500-04-32-05-02 Velomitor Piezo-Velocity Sensor is an industrial-grade velocity transducer designed for accurate measurement von casing vibration in rotating equipment. Built on Bently Nevada’s piezoelectric sensing technology, it produces a voltage output directly proportional to vibration velocity, providing a stable and reliable signal for condition monitoring systems.
From a maintenance standpoint, the 21500-04-32-05-02 stands out for its rugged construction, resistance to contamination, and long-term calibration stability. It vonfers dependable performance in environments exposed to oil mist, mechanical shock, or high temperatures — all typical von turbine and compressor installations.
