Bently Nevada 31000-16-10-15-070-03-02 Sensor Housing

Product Overview

The Bently Nevada 31000-16-10-15-070-03-02 is a high-performance housing assembly optimized for the 3300 XL 8 mm proximity probe series. This 1.2 kg unit is engineered to provide a secure and hermetically sealed environment for critical displacement sensors used on large rotating machinery. The housing body is made from advanced glass-reinforced PPS thermoplastic, which integrates conductive fibers to satisfy CENELEC EN50014 standards for electrostatic dissipation. This specific configuration provides a deep 7.0-inch penetration (Option 070) and a 1.5-inch standoff (Option 15).

Mechanical Integrity & Strength

Designed to endure the physical rigors of industrial sites, the 31000-16-10-15-070-03-02 features a sleeve and retaining chain made of AISI 304 stainless steel, while exterior screws are AISI 303. Despite its 1.2 kg weight, the housing is exceptionally strong, capable of supporting a 912 N (205 lb) load at the unsupported end. For a secure installation, the 3/4-14 NPT mounting thread should be tightened to a recommended torque of 29.4 N·m (260 in·lb), ensuring the internal 1.0 m (39 in) probe cable remains protected from environmental stress.

Technical Specifications

Environmental Protection & Certifications

The Bently Nevada 31000-16-10-15-070-03-02 is rated for extreme operating temperatures from -51°C to +105°C. It carries a Type 4X rating from the CSA and an IP66 rating for ingress protection, making it suitable for high-pressure wash-down areas. The unit is impact-tested by BASEEFA to withstand 4 Joules at temperature extremes and 7 Joules at room temperature. This level of protection ensures that your 3300 XL probe remains operational regardless of moisture, chemical exposure, or physical impact.

Flexible Installation Options

The "03" fitting option included with this 1.2 kg assembly provides a 3/4-14 to 1/2-14 NPT stainless steel reducer and a versatile cable seal grip. To ensure compatibility with various field wiring, the kit includes grommets for cable sizes ranging from 1/8 to 3/8 inches. The 3/4-14 NPT mounting thread (Option 02) is required for the standoff adapter, providing a robust mechanical interface between the housing and the machine casing.

Technical FAQs

Q1: Why is the 7.0-inch penetration depth useful?
A1: The 7.0" penetration depth (Option 070) allows the probe to reach through thick machine casings or internal structures to accurately measure shaft position.

Q2: Is the Bently Nevada 31000-16-10-15-070-03-02 hazardous area rated?
A2: Yes, the PPS housing material is designed for electrostatic dissipation and meets CENELEC EN50014 standards for hazardous areas.

Q3: What cable length is standard with this part number?
A3: This specific configuration includes a 1.0-meter (39-inch) cable for the 3300 XL 8 mm probe.
