Product Overview

The Bently Nevada 31000-16-10-00-162-00-02 is a heavy-duty, front-mount proximity probe housing assembly engineered to protect and precisely position 3300 XL 8mm transducers. This assembly is a critical component of Turbine Supervisory Instrumentation (TSI), designed to facilitate the installation of proximity probes through machine casings or bearing housings. By utilizing an AISI 304 stainless steel explosion-proof housing, it provides an environmental seal and mechanical protection for the probe and its connection. This specific configuration allows for external adjustment of the probe gap, enabling technicians to calibrate the sensor without dismantling the machinery, thereby significantly reducing maintenance labor and operational downtime.

Industrial Applications and Operational Benefits

The 31000-16-10-00-162-00-02 housing is the industry standard for protecting vibration sensors on large-scale rotating equipment. Its robust architecture is essential for several key sectors:

• Steam and Gas Turbines Protecting radial vibration and axial thrust probes from high-velocity oil mist and thermal cycling.

• Centrifugal Compressors Ensuring stable probe positioning for shaft orbit monitoring in high-pressure gas environments.

• Power Generation Facilities Providing a secure mounting point for Keyphasor and speed sensors on main generator shafts.

• Petrochemical Refineries Facilitating hazardous area compliance for sensors mounted on critical process pumps and expanders.

• External Gap Adjustment Allowing maintenance teams to verify or adjust probe voltage gaps through the housing cover, preventing the need for machine casing removal.

By providing a rigid mounting platform, the 31000 assembly eliminates "probe chatter" and mechanical drift, ensuring that the 4-20mA or dynamic signals sent to the 3500/42M monitoring rack are accurate and free from false-alarm interference.
