Bently Nevada 31000-28-10-00-020-03-02 English Proximity Probe Housing Assembly

Description

The 31000-28-10-00-020-03-02 is an English proximity probe housing assembly designed for the 3300 XL 8 mm transducer system, featuring a connector protector and a 1.0 m probe cable. This assembly allows for the external mounting of proximity probes through the machine case, facilitating maintenance access for gap adjustment or probe replacement without requiring machine disassembly. The housing is constructed from high-strength, corrosion-resistant polyphenylene sulfide (PPS) and incorporates stainless steel components to ensure environmental and mechanical protection for the installed transducer. This specific configuration includes a 2.0 inch (Option 020) probe penetration depth and is configured with two plugs and one M20 fitting (Option 03) for cable sealing, utilizing a 3/4-14 NPT mounting thread. The assembly adheres to the American Petroleum Institute (API) 670 standard for externally mounted proximity probe housings, making it a suitable choice for radial vibration and Keyphasor measurement applications in critical rotating machinery environments.

Features

• Integrated 3300 XL 8 mm proximity probe with connector protector (Option 28)

Installation Guidelines

• Install the outer sleeve into the machine case before mounting the housing.
• Ensure the housing is configured with correct fittings for your cabling requirements; use provided hole plugs to seal unused ports.
• When measuring radial vibration, ensure the machine casing is securely affixed to the bearing to maintain an accurate relative vibration signal.
• Tighten hole plug nuts to 0.5 N-m (5 in-lbs) during installation.
• For penetration depths less than 1.0 inch, counter-bore the machine case if necessary to minimize rear or side view effects.

Compliance and Certifications

• API 670 Standard (Externally mounted proximity probe housings)
