330101-00-14-90-02-CN Bently Nevada 3300 XL Probe

Product Overview

The Bently Nevada 330101-00-14-90-02-CN is an ultra-long reach 3300 XL 8 mm Proximity Transducer Probe designed for demanding vibration and position measurement in heavy industrial machinery. Featuring a compact 1.4-inch (35.6 mm) 304 stainless steel case with 3/8-24 UNF threads and an extended 9.0-meter (29.5 feet) standard coaxial cable without armor, this sensor delivers precise 7.87 V/mm (200 mV/mil) sensitivity across an extreme operating temperature range of -62°F to +500°F (-52°C to +260°C). Weighing approximately 0.45 kg (1.00 lbs), it incorporates ClickLoc™ connectors and 3-layer epoxy encapsulation for maximum reliability under severe vibration shocks.

Core Technical Advantages

Extended 9.0m Cabling Reach: The integrated 9-meter (29.5 ft) cable allows direct connection to field junction boxes across vast machine footprints, reducing inline connector failure points.

Extreme Thermal Range (-62°F to +500°F): Built with high-grade 304 stainless steel and 3-layer epoxy encapsulation, engineered to withstand arctic cold and extreme furnace temperatures.

High Shock & Slurry Pressure Resistance: Validated for high-impact environments with up to 200G vibration shock resistance and 0 failures under 480 PSI slurry pressure testing.

Technical Specifications

Installation and Maintenance

Gap Setting & Mounting: Thread the 1.4-inch 304 SST case into the tapped hole and adjust to an optimal physical gap of 1.27 mm, corresponding to a nominal bias voltage of -9V DC.

Cabling & Mechanical Protection: Route the 9-meter coaxial cable using shielded 16-24 AWG triad extension wiring. Ensure a minimum 75 lb cable retention strain relief to prevent connection pulling.

Engineering Advantages

3-Layer Epoxy Encapsulation Protection

Protects inner coil elements and internal wiring from fluid ingress, corrosive chemicals, and high-pressure washing in tough mining and pump applications.

Low-Humidity Drift Signal Accuracy

Exhibits less than 3% variance at 93% relative humidity, ensuring rock-solid vibration baseline measurement without signal drift over extended continuous duty.

Validated High-Shock Resistance

Field validated in heavy-duty copper extraction pumps, maintaining ±0.018 mm average measurement accuracy under continuous 200G vibration shock loads.
