• Nominal Probe DC Resistance (0.5m): 7.45 ± 0.50 ohms.
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Field Wiring: 0.2 to 1.5 mm² (16 to 24 AWG), maximum length 305 meters (1,000 feet).

The 330101-00-08-05-12-CN offers a recommended gap setting of -9 Vdc for radial vibration, approximately 1.27 mm (50 mils). Its deviation from best fit straight line (DSL) is less than ±0.025 mm (±1 mil) for standard 5 or 1 meter systems at 0°C to +45°C.

Applications and Use Cases

In rotating machinery monitoring, the 330101-00-08-05-12-CN excels at measuring shaft vibration and position. It is ideal for turbines, compressors, and pumps where precise gap and vibration data prevent unplanned downtime. Furthermore, its robust design withstands harsh conditions, making it suitable for oil and gas, power generation, and petrochemical industries.

Installation and Setup Guide

Mount the 3300 XL 8 mm probe using the 3/8-24 UNF thread into a suitable mounting hole. Ensure the target surface is clean and within the linear range of 0.25 to 2.3 mm (10 to 90 mils). Connect the miniature coaxial ClickLoc connector to the extension cable, and route the FluidLoc cable to avoid sharp bends. For field wiring, use a 3-conductor shielded triad cable with tinned ends, keeping total length under 305 meters (1,000 feet).

Maintenance and Reliability

Regularly inspect the probe tip and cable for physical damage. The PPS tip and stainless steel case resist corrosion and wear. Operating within the specified temperature range (-52°C to +177°C) ensures long-term accuracy. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure. Routine checks of the connector and cable integrity help maintain reliable performance.

Compatibility and Integration

The 330101-00-08-05-12-CN integrates with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. It works with standard 5 or 1 meter systems and extended temperature range configurations. The probe's 7.87 V/mm output is compatible with most vibration monitoring modules that accept -1 to -17 Vdc signals.
