Bently Nevada 330180-90-00 3300 XL Proximitor Sensor

Description

330180-90-00: 3300 XL Proximitor Sensor, configured for a 9.0-meter system length with standard panel-mount housing and no hazardous area agency approvals. This configuration conditions and drives the proximity probe signal in machinery protection networks, outputting a continuous analog DC voltage proportional to the dynamic gap distance between the probe tip and the target material.

Unlike the 1.0-meter or 5.0-meter variants, this 9.0-meter system version matches the combined impedance requirements of 3300 XL 8 mm proximity probes and extension cables calibrated to a total 9.0-meter physical length. The integrated base plate provides galvanic isolation without separate insulating hardware, minimizing installation footprint and simplifying direct mounting to equipment panels or junction enclosures.

Features

• 9.0-meter total system length tuning matches specific 3300 XL probe and extension cable pairings
• Integrated panel-mount base footprint for mounting directly to bulkheads or inside instrument enclosures
• Spring-loaded terminal strips accept tinned field wiring without screw clamping mechanisms
• Constructed with an A308 aluminum housing and gold-plated coaxial connectors
• High immunity to radio frequency interference allows mounting inside non-metallic enclosures

Applications

Typical applications include shaft vibration, axial position, and speed measurements on rotating machinery such as steam turbines, gas compressors, industrial pumps, and electric motor bearings.

Installation Guidelines

Install the panel-mount base directly to a flat, electrically conductive surface using the integrated mounting plate. Use standard 3-conductor shielded triad field cable (18 AWG / 1.0 mm2 recommended) to connect the terminal strips to the monitoring rack system. Ensure that the total loop length of the probe and extension cable is exactly 9.0 meters to maintain calibration with the sensor. Connectors must be kept clean, dry, and protected using connector protectors or self-fusing tape when exposed to harsh environments.

Compliance and Certifications

Complies with European CE Mark requirements for electromagnetic compatibility and RF/EMI immunity without the need for auxiliary metal conduit or enclosures. Complies with FCC part 15 rules.
