Bently Nevada 330701-01-20-10-02-00 Proximity Probe

Bently Nevada 330701-01-20-10-02-00 Proximity Probe

Product Introduction

The 330701-01-20-10-02-00 belongs to the Bently Nevada 3300 XL series. Specifically, it is an 11 mm proximity probe with a 1/2-20 UNF thread and no armor. This probe measures shaft vibration, radial position, and axial displacement in rotating machinery. Furthermore, it fits steam turbines, pumps, and compressors with limited radial clearance. The model 330701-01-20-10-02-00 adds a 1.0 inch unthreaded length and a 2.0 inch case.

Technical Specifications

First, the probe tip uses Polyphenylene sulfide (PPS). The probe case is AISI 304 stainless steel (SST). Additionally, the cable is a 75 Ω triaxial, fluoroethylene propylene (FEP) insulated probe cable. Its total length is 1.0 meter (3.3 feet).

Moreover, the connector option is a Miniature coaxial ClickLoc connector with a standard cable. This model does not include FluidLoc cable or armor. The agency approval option is 00, which means no approval is required. Meanwhile, the unthreaded length is 1.0 inch, and the overall case length is 2.0 inches.

The probe dc resistance from the center conductor to the outer conductor is 5.9 ± 0.5 ohms at 1.0 m. Besides, the unthreaded section allows the probe body to sit clear of the mounting surface.

Mechanical and Environmental Parameters

The operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). However, temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe case thread is 1/2-20 UNF. Its maximum thread engagement length is 0.750 inches.

For torque, the maximum rated value is 45.2 N•m (400 in•lb). The recommended torque is 15.2 N•m (133 in•lb). The connector-to-connector torque is finger tight, with a maximum of 0.565 N•m (5 in•lb). In addition, the minimum bend radius is 25.4 mm (1.0 in), with or without SST armor.

The probe pressure seal uses a Viton O-ring. Therefore, it seals differential pressure between the probe tip and case. However, probes are not pressure tested before shipment. For a pressure seal test, contact the custom design department.

Installation Guide

Next, mount the probe using the 1/2-20 UNF thread. Apply the recommended torque of 15.2 N•m (133 in•lb). Do not exceed 45.2 N•m (400 in•lb). Meanwhile, keep the minimum bend radius at 25.4 mm (1.0 in). Connect the ClickLoc connector by hand. Finally, tighten it to no more than 0.565 N•m (5 in•lb). The 1.0 inch unthreaded length also aids alignment in thick brackets.
