Bently Nevada 330708-00-10-10-12-05 Probe

Product Introduction

This Bently Nevada 330708-00-10-10-12-05 proximity probe belongs to the 3300 XL 11 mm family. Specifically, it measures shaft vibration and position in rotating machinery. The probe uses a 5/8-18 UNF thread without armor. Moreover, its overall case length is 1.0 inch with no unthreaded section. The total length reaches 1.0 metre (3.3 feet). Meanwhile, the miniature coaxial ClickLoc connector and FluidLoc cable simplify wiring and block oil leakage. Finally, the multiple approvals option supports use across several regions.

Technical Specifications

The electrical and material choices of the 330708-00-10-10-12-05 support stable measurement. First, the probe DC resistance from center conductor to outer conductor is 5.9 ± 0.5 Ω at 1.0 metre. The cable itself is 75 Ω triaxial with FEP insulation. Additionally, the probe tip uses polyphenylene sulfide (PPS). The case is built from AISI 304 stainless steel. These materials resist corrosion and wear in harsh plant conditions. The probe seals differential pressure with a Viton O-ring between tip and case.

Mechanical and Environmental Parameters

Mechanical limits matter for long service life. The 330708-00-10-10-12-05 case thread is 5/8-18 UNF with a maximum thread engagement of 0.938 inch. The recommended case torque is 15.2 N·m (133 in·lb), while the maximum rated torque is 45.2 N·m (400 in·lb). Connector torque should be finger tight, capped at 0.565 N·m (5 in·lb). Furthermore, the minimum bend radius is 25.4 mm (1.0 in). The operating and storage range spans -52°C to +177°C (-62°F to +351°F). However, exposure below -34°C may cause premature pressure seal failure.

Installation Guide

Proper mounting protects accuracy and probe life. First, verify the target material and set the gap per system requirements. Next, thread the probe into the case and tighten to the recommended torque. Avoid overtightening beyond the rated maximum. Additionally, route the cable with a bend radius above 25.4 mm. Keep the cable away from hot surfaces and sharp edges. Finally, hand-tighten the ClickLoc connector only, since excess force can damage the coaxial joint.
