31000-28-10-00-047-03-02 Bently Nevada Proximity Probe Housing Assemblies

Description:

The 31000/32000 series proximity probe housing assembly is recommended for mounting proximity probes through the machine housing, typically for radially mounted sensors, whether for vibration or key phase measurements.

Using the proximity probe housing allows for easy external access to the proximity probe and its extension cables, enabling gap adjustment or probe replacement without disassembling the machine.

The 31000/32000 series proximity probe housing assembly is made of polyphenylene sulfide (PPS), an advanced high-strength thermoplastic material with excellent corrosion resistance.

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: 2 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.
