The 31000 series probe‑housing from Bently Nevada is designed to house one of their proximity probes (e.g., from the 3300 XL family) and mount it through a machine case. The housing
provides mechanical, environmental and mounting support, enabling the probe to be installed and adjusted without disassembling the machine casing.a housing labeled
“31000‑28‑05‑00‑037‑03‑02” likely means: 31000 series housing, configured with a 3300 XL 8 mm probe (multiple approvals), 0.5 m cable,
no standoff, penetration 3.7 in, fittings option #3, mounting thread ¾‑14 NPT.

FAQ |
|
Q1: What exactly does this housing protect against and what doesn’t it? like IP66 (dust-tight, water jets) and 4X (corrosion‑resistant) when installed. However, it is not explosion‑proof unless specifically configured or unless you select a different housing (for explosion‑proof you’d use e.g. the 21000 or 24701 series). |
|
Q2: Can I use this housing in a high‑temperature or high‑pressure environment? extreme temperatures, you’ll need to verify special materials/options. For pressure: It is designed for mechanical protection, but the datasheet explicitly notes that it is not designed to resist internal or external pressure (i.e., it is not pressure‑sealed for high pressure fluid environments). |
|
Q3: How do I adjust the probe gap / replace the probe without disassembling the machine? so you can access the probe and extension cable. According to the specification: “Use of a Proximity probe housing allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine.” |
