Product Overview
The Bently Nevada 330180-92-CN is a 3300 XL Proximitor Sensor designed for non-contacting displacement measurement in industrial machinery protection systems. It accepts one 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable, providing a 9.0 meter (29.5 foot) system length with no mounting hardware. The sensor's improved RFI/EMI immunity eliminates the need for special shielded conduit or metallic housings, reducing installation cost and complexity. Its compact packaging supports high-density DIN-rail mounting or traditional panel mount with a 4-hole footprint compatible with older Proximitor designs.

Applications
The Bently Nevada 330180-92-CN suits steam turbine monitoring, where its 9.0 m system length reaches probes mounted on bearing housings. In compressor trains, the 50 Ω output resistance ensures stable signal transmission to monitors. The sensor's -52°C to +100°C operating range handles extreme plant environments. For petrochemical facilities, the CN country-specific approval meets local regulatory requirements. PLC Source PRO supplies genuine Bently Nevada parts with fast quote response and technical support for selecting compatible probes and extension cables.
Compatibility and Selection Guide
Use the 330180-92-CN with one 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable. The total system length of 9.0 meters (29.5 feet) must match the probe and extension cable lengths to maintain calibration. The sensor requires -17.5 Vdc to -26 Vdc when installed per non-incendive circuit drawing 140979, or -23 Vdc to -26 Vdc with barriers. Operation above -23.5 Vdc reduces linear range. The 4-hole mounting footprint is identical to older Proximitor Sensor designs, allowing drop-in replacement. For high-density installations, DIN-rail mounting is supported. The A308 aluminum housing provides electrical isolation, eliminating separate isolator plates.
Installation and Maintenance
Mount the 330180-92-CN using either DIN-rail or panel mount with the 4-hole footprint. The SpringLoc terminal strips require no special tools and create robust field wiring connections that resist loosening. No separate isolator plates are needed because the mounting base provides electrical isolation. The gold-plated brass or beryllium copper connectors ensure reliable signal contact. Store the sensor between -52°C and +105°C. For operational reliability, verify supply voltage stays within -17.5 Vdc to -26 Vdc (non-incendive) or -23 Vdc to -26 Vdc (with barriers). The 246 g (8.67 oz) weight and compact size simplify installation in tight cabinets.
