330180-92-CN Bently Nevada 3300 XL Proximitor Sensor 9.0m

Case Study: Solving High-Density DIN-Rail Integration with the 330180-92-CN

A petrochemical plant faced a critical challenge: integrating proximity probe systems into a high-density DIN-rail cabinet without compromising signal integrity. Traditional Proximitor sensors required separate isolator plates and extensive shielding, increasing installation complexity and cost. The Bently Nevada 330180-92-CN 3300 XL Proximitor Sensor solved this by providing electrical isolation directly through its mounting base, eliminating the need for separate isolators. With a 9.0-meter (29.5-foot) system length and no mounting hardware, this sensor streamlined the installation while maintaining engineering-grade precision.

330180-92-CN Technical Specifications and Key Features

The 330180-92-CN is a 3300 XL Proximitor Sensor manufactured by Bently Nevada, designed for non-contacting 3300-series 5 mm and 3300 XL 8 mm proximity probes with extension cables. Its A308 aluminum housing ensures durability, while gold-plated brass or beryllium copper connectors provide reliable signal transmission. The sensor operates with a supply sensitivity of less than 2 mV output voltage change per volt input change, ensuring stable measurements. Output resistance is 50 Ω, and the operating temperature range spans -52°C to +100°C (-62°F to +212°F), with storage from -52°C to +105°C (-62°F to +221°F). The 330180-92-CN requires -17.5 Vdc to -26 Vdc when installed with a nonincendive circuit per installation drawing 140979, consuming 12 mA maximum; with barriers, -23 Vdc to -26 Vdc is required. Operation at a more positive voltage than -23.5 Vdc can reduce linear range.

Installation and Integration of the 330180-92-CN

The 330180-92-CN features SpringLoc terminal strips that require no special tools, enabling faster and more robust field wiring by eliminating screw-type clamps that can loosen. Its physical packaging supports high-density DIN-rail installations and traditional panel mount configurations with a 4-hole footprint identical to older Proximitor designs. The mounting base provides electrical isolation, removing the need for separate isolator plates. Furthermore, the sensor's high immunity to radio frequency interference allows installation in fiberglass housings without adverse effects from nearby RF signals, satisfying European CE mark approvals without special shielded conduit or metallic housings. This reduces installation costs and complexity.
