Bently Nevada 31000-30-05-15-31-03-02 English Proximity Probe Housing Assembly

Description

The 31000-30-05-15-31-03-02 English Proximity Probe Housing Assembly is an engineered solution for mounting proximity probes through machine casings, ensuring consistent and accurate measurement for radial vibration and keyphasor applications. This specific configuration includes the 3300 XL NSv probe with a connector protector (Option 30), a 0.5 meter probe cable (Option 05), a 150 mm standoff adapter length (Option 15), and a 31 mm probe penetration depth (Option 31).

Constructed from polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, this assembly is built to comply with API 670 standards for externally mounted proximity probe housings. It provides mechanical and environmental protection for the transducer system while allowing external access for gap adjustment and probe replacement without requiring the disassembly of the machine case. This unit is equipped with two plugs and one M20 fitting (Option 03) and features a 3/4-14 NPT mounting thread (Option 02).

Features

• Option 30: Integrated 3300 XL NSv probe with connector protector for reliable signal transmission.
• Option 05: 0.5 m (20 in) probe cable length suitable for standard machine mounting.
• Option 15: 150 mm standoff adapter length.
• Option 31: 31 mm probe penetration adjustment range.
• Option 03: Two plugs and one M20 fitting configuration.
• Option 02: 3/4-14 NPT mounting thread for secure installation.
• Compatible with 3300 XL NSv proximity transducer systems.
• API 670 compliant design for harsh industrial machinery environments.

Applications

Used for protecting proximity probes in power generation, oil and gas, and petrochemical rotating machinery. Essential for monitoring shaft axial position and radial vibration in environments requiring external access to transducers.

Ordering Information

Technical Specifications

Installation Guidelines

Ensure the machine casing is properly affixed to the bearing to maintain accurate vibration signals. When installing, insert the probe sleeve into the machine case, adjust the gap, and then fit the housing over the outer sleeve. Secure the assembly using the retaining nut and ensure that all conduit fittings are tightened according to torque specifications to maintain environmental seals.

Compliance and Certifications

Compliant with API 670 Standards for externally mounted proximity probe housings. Suitable for use in intrinsically safe hazardous area applications when installed with appropriate I.S. barriers and transducer systems.
