Product Description
21000-00-00-00-019-03-02 Bently Nevada Aluminum Proximity Probe Housing Assembly
Engineered with a copper-free cast aluminum body and a rugged 304 stainless steel protection sleeve, the Bently Nevada 21000-00-00-00-019-03-02 external probe housing allows technicians to mechanically adjust, gap, or replace proximity sensors without shutting down critical rotating assets. It solves the costly industrial pain point of unexpected production halts and premature sensor degradation caused by high-pressure oil currents or physical impacts within harsh machinery casings. Featuring a compact 0.0-inch standoff design, a 1.9-inch penetration sleeve, and explosion-proof thread fittings, it is the ideal choice for mounting reverse-mount proximity probes on high-speed centrifugal compressors, small gearboxes, and multi-stage process pumps across oil refineries and power plants.
Engineer's Note
"Our chief instrumentation engineer suggests selecting the 21000-00-00-00-019-03-02 model for machinery envelopes with tight overhead clearances because its 0.0-inch standoff profile minimizes the housing's total external height. When installing, verify that the target machine casing is perfectly tapped for a 1/2-14 BSP metric thread. Because this specific option utilizes a short 1.9-inch internal sleeve, it is ideally matched for standard 3300 XL 8mm reverse-mount probes; always ensure that your field team greases the o-ring seal during entry to guarantee the assembly maintains its Type 4 weatherproofing."
Project Case
"This exact 21000 probe housing configuration was successfully deployed for a multi-stage process gas pump line at a maritime refinery in 2025, operating flawlessly under corrosive marine air and continuous high-velocity spray. By relocating the plant's internal proximity sensors out to this externally accessible aluminum housing dome, plant maintenance teams reduced the time required to calibrate and adjust the sensor's voltage gap from a 4-hour machinery shutdown down to a 10-minute online task."
Frequently Asked Questions
Q: Does the 0.0-inch standoff option affect the safety rating in explosive hazardous areas?
A: No. The 0.0-inch standoff (Option -00) simply alters the physical exterior profile. When installed with the included '03' explosion-proof fittings and a certified Bently Nevada reverse-mount probe, this entire aluminum enclosure carries full CSA/ATEX hazardous area certifications for Class I, Division 1 (Zones 1 and 2) layouts.
Q: Can this specific 21000 configuration be utilized with forward-mount standard proximity probes?
A: No, this enclosure sleeve is bored exclusively to retain reverse-mount proximity sensors (such as the 3300 XL 8mm 330906 or 330907 series). The probe must be inserted from the rear of the internal sleeve assembly to allow for external online gapping adjustments.
Q: What should we do if our process fluid contains high concentrations of sour gas (H2S)?
A: If your machinery handles highly corrosive sour gas, the cast aluminum body of the 21000 series might be prone to surface degradation over time. For highly corrosive chemical plants, our engineering team recommends upgrading your project specification to the Bently Nevada 24701 series, which offers an identical form factor but upgrades the chassis to full 303 stainless steel.
