Extended-Reach Proximity Probe Housing for Critical Rotating Equipment
The Bently Nevada 21000-16-10-15-227-03-02 Proximity Probe Housing Assembly is a heavy-duty external mounting solution designed to provide secure installation and environmental protection for proximity probes used in machinery protection systems. As part of the trusted 21000 Proximity Probe Housing Assembly series, this model simplifies probe installation, adjustment, and maintenance while shielding the sensing assembly from moisture, oil, dust, and mechanical damage. It is widely deployed on turbines, compressors, pumps, and other rotating assets where reliable vibration and shaft position monitoring are essential for maximizing equipment availability and minimizing unplanned downtime.
This configuration includes a 3300 XL 8 mm reverse-mount proximity probe, a 1.0 m (39 in.) probe cable, a 1.5 in. (38 mm) standoff adapter, an 22.7 in. (577 mm) probe penetration, fitting option 03 with cable seal components, and a 3/4-14 NPT mounting thread. The extra-long probe penetration makes this assembly particularly suitable for deep bearing housings and machinery requiring extended probe reach.
