Bently Nevada 31000-30-05-15-049-03-02 31000 Proximity Probe Housing

Product Introduction

The Bently Nevada 31000-30-05-15-049-03-02 belongs to the trusted 31000 series of probe housings. This unit specifically accommodates the 3300 XL 8 mm probe with a connector protector, carrying multiple approvals for global applications. The housing provides secure mounting and exceptional environmental protection. Its rugged construction makes it ideal for monitoring vibration and position in turbines, compressors, and other critical rotating machinery. The housing's design simplifies installation while ensuring reliable sensor performance in harsh conditions.

Technical Specifications

The 31000-30-05-15-049-03-02 model offers a precise configuration for demanding measurement applications. First, the "30" option designates compatibility with the 3300 XL 8 mm probe that includes a connector protector and multiple agency approvals. The probe cable length measures 0.5 meter (20 inches), which suits installations with limited space or short routing requirements.

Additionally, this housing includes a standoff adapter option with a minimum length of 1.5 inches (38 mm). This adapter positions the probe correctly for optimal sensing accuracy. The probe penetration option measures 4.9 inches, allowing precise insertion depth into the measurement zone. The fittings option includes two plugs and one 3/4-14 to 1/2-14 NPT stainless steel reducer. Moreover, it comes with a cable seal grip that accommodates multiple cable sizes: 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches. The mounting thread is 3/4-14 NPT, which is required when ordering the standoff adapter option.

Protection and Environmental Ratings

The Bently Nevada 31000-30-05-15-049-03-02 excels in harsh environments due to its superior protection features. The Canadian Standards Association (CSA) certifies this housing with a Type 4X rating, which ensures resistance to corrosion, water ingress, and ice formation. Furthermore, it carries an IP66 rating, as verified by SC115582-1 (e) 106. This rating guarantees complete protection against dust ingress and powerful water jets from any direction.

Moreover, the housing meets CENELEC standard EN50014 for electrostatic dissipation. This feature prevents static charge accumulation on the plastic material, which is crucial for installations in hazardous areas. The housing material uses glass-reinforced Polyphenylene Sulfide (PPS) thermoplastic with conductive fibers. This advanced composition provides excellent mechanical strength and electrical conductivity. The sleeve and retaining chain use AISI 304 stainless steel, while the outer sleeve and exterior screws use AISI 303 stainless steel. Neoprene® O-rings provide effective sealing against moisture and contaminants.

Mechanical and Temperature Parameters

The mechanical design of the 31000-30-05-15-049-03-02 ensures long-lasting performance in demanding conditions. The housing demonstrates exceptional impact strength. BASEEFA certified it to withstand two separate 4 Joule (3.0 ft·lb) impacts at -39°C (-38°F) and at 115°C (239°F). Additionally, CSA verified that samples of the housing and cover can withstand a 7 Joule (5.2 ft·lb) impact at ambient room temperature. This robust construction protects the internal probe from accidental strikes or mechanical shock.

The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). Adhering to this torque specification prevents over-tightening and ensures a proper environmental seal. The housing can support a significant load without deformation. In a typical test, it supported 912 N (205 lb) placed approximately 38 mm (1.5 inches) from the unsupported end. This structural strength guarantees that the housing maintains its integrity even under mechanical stress from connected cables or external forces.

The operating temperature range is broad, spanning from -51°C to +105°C (-60°F to +221°F). This wide range allows the 31000 Proximity Probe Housing to function reliably in both extreme cold and high heat. The housing weighs 1.2 kg (2.6 lb) typically, making it substantial yet manageable for installation personnel.

Installation Guidelines

Proper installation of the Bently Nevada 31000-30-05-15-049-03-02 ensures optimal probe performance and longevity. Begin by selecting the correct cable seal grip grommet that matches your probe cable diameter. The kit includes grommets for three cable sizes: 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches. Choose the one that provides a snug fit for your specific cable.

Next, thread the housing into the mounting hole using the 3/4-14 NPT thread. Apply thread sealant to prevent leaks and ensure a gas-tight seal. Insert the 3300 XL 8 mm probe through the housing and adjust the penetration to the required 4.9 inches. The connector protector on the probe safeguards the connection point during installation and operation. Tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb). Finally, route the probe cable through the cable seal grip and tighten it securely. This procedure protects the cable from strain, abrasion, and environmental damage, ensuring reliable long-term operation.
