Product Overview

Probe Design and Chemical Resistance

The Bently Nevada 330907-05-30-10-12-05 is a 3300 NSv Reverse Mount Probe manufactured in the USA. Therefore, this probe offers increased chemical resistance compared to the 3300 RAM probe. Consequently, the 330907-05-30-10-12-05 suits many process compressor applications. The side-view characteristics are also superior to those of the 3000-series 190 probe. As a result, you get more accurate measurements when gapping at the same distance from the probe target.

Thread and Connector Specifications

The reverse mount 3300 NSv probe comes standard with M10X1 threads. Therefore, the 330907-05-30-10-12-05 uses M10X1 probe threads for secure installation. All components of the transducer system feature gold-plated brass ClickLoc connectors. Consequently, these connectors lock into place and prevent loosening from vibration. The FluidLoc cable option prevents oil and other liquids from leaking out of the machine through the cable interior.

Patented Manufacturing Methods

The patented TipLoc molding method provides a robust bond between the probe tip and the probe body. Therefore, the probe withstands harsh industrial environments without failure. The probe cable is securely attached to the probe tip using the patented CableLoc design. Consequently, the connection provides exceptional pull strength for reliable operation.

Installation Guide

Follow these steps to install the Bently Nevada 330907-05-30-10-12-05 correctly.

1. Prepare Mounting Hole: First, ensure the M10X1 threaded hole is clean and undamaged.

2. Apply Lubricant: Next, apply anti-seize compound to the probe threads for easier installation.

3. Hand Tighten Probe: Then, thread the 330907-05-30-10-12-05 into the mounting hole by hand.

4. Torque to Specification: After that, tighten to 7.5 N•m (66 in•lb) recommended torque.

5. Connect Cable: Meanwhile, attach the miniature coaxial ClickLoc connector until it locks.

6. Set Gap: Finally, adjust the probe gap to 1.0 mm (40 mils) for optimal performance.

The 330907-05-30-10-12-05 requires careful attention to torque limits. Therefore, do not exceed 22.6 N•m (200 in•lb) maximum rated torque. In addition, avoid sustained low temperatures below -34°C to protect the pressure seal. Consequently, proper installation ensures long-term reliability and measurement accuracy.
