31000-00-00-00-031-01-02 Bently Nevada Proximity Probe Housing

Description:

31000-00-00-00-031-01-02 is a housing assembly for the Bently Nevada 31000 series non-explosion-proof eddy current probe. It is designed for external mounting of 3300 XL series eddy current probes on rotating machinery (steam turbines, compressors, motors, etc.) for monitoring shaft vibration, shaft displacement, and key phase. It is non-explosion-proof and only provides mechanical/environmental protection.

Model and Suffix Codes:

Features:

• Maintenance-Free

Probe gap adjustment and probe/cable replacement can be performed externally without disassembling the device itself.

• Corrosion-Resistant and Durable

PPS material is oil-resistant, acid and alkali-resistant, and anti-aging, suitable for petrochemical, power, and other industrial environments.

• Easy Installation

Standard 3/4-14 NPT thread, compatible with mainstream equipment mounting holes, with a clearly defined torque range.

• Intrinsically Safe Compatible

When paired with an intrinsically safe probe and safety barrier, it can be used in Zone 1/2 hazardous environments (non-explosion-proof).

• Accuracy Guaranteed

Strictly adheres to API 670, ensuring probe mounting coaxiality and gap stability.

FAQ:

1.Is there stock available or how long is the lead time?

Lead time:12 weeks
2. What are the differences between the 31000 and 21000 series explosion-proof enclosures?

31000: PPS material, lightweight, non-explosion-proof, IP66, low cost, used in general areas or intrinsically safe systems.
21000: Aluminum alloy, explosion-proof certified, heavier, for direct installation in Zone 1/2 hazardous locations.
3. What should be checked during routine maintenance?
Check for loose enclosure fasteners; check for aging or water leakage in sealing plugs and O-rings; check for reliable probe mounting and gap drift; check for proper shielding and grounding to prevent signal interference.
