Product Introduction
The Bently Nevada 21000-00-00-00-039-03-02 Proximity Probe Housing Assembly is a precision-engineered mechanical accessory designed to provide stable, repeatable, and environmentally protected mounting for proximity probes used in rotating machinery condition monitoring systems. This housing assembly plays a critical role in ensuring the measurement accuracy and long-term reliability of non-contact displacement and vibration monitoring by maintaining correct probe alignment and mechanical integrity under demanding industrial conditions.
Unlike simple mounting brackets, the 21000 series housing is designed as a structural interface between the machine casing and the proximity probe, allowing the probe to be positioned accurately relative to the monitored shaft or target surface. Its rigid construction minimizes mechanical resonance, relative movement, and thermal distortion, all of which can directly affect probe output stability.
This specific configuration, with a housing body diameter of 83.3 mm, is intended for installations where enhanced mechanical strength and robust environmental resistance are required, such as large rotating machines, heavy-duty compressors, turbines, and motors. The assembly is suitable for integration into Bently Nevada proximity probe systems used in critical machinery protection and condition monitoring applications.
