330180-50-00 Bently Nevada 3300 XL Proximitor Sensor 5.0m

Product Overview: Bently Nevada 330180-50-00

The Bently Nevada 330180-50-00 is a 3300 XL Proximitor Sensor engineered for precise, non-contacting displacement measurement in industrial machinery protection systems. As part of the 3300 XL series, this sensor incorporates numerous improvements over previous designs, delivering engineering-grade precision in a compact, panel-mount package. Its physical packaging supports high-density DIN-rail installations while maintaining an identical 4-hole mounting footprint with older Proximitor Sensor designs. The mounting base provides electrical isolation, eliminating the need for separate isolator plates. This unit features a 5.0-meter (16.4-foot) system length and panel mount configuration, making it suitable for a wide range of turbine and compressor monitoring applications.

Technical Specifications and Key Features

The 330180-50-00 operates with a -17.5 Vdc to -26 Vdc power supply when installed with a nonincendive circuit per installation drawing 140979, drawing a maximum of 12 mA. When used with barriers, the required voltage range is -23 Vdc to -26 Vdc. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range. The supply sensitivity is less than 2 mV change in output voltage per volt change in input voltage, ensuring stable performance under varying supply conditions. The output resistance is 50 Ω. The Proximitor Sensor housing is constructed from A308 aluminum, while the connector features gold-plated brass or gold-plated beryllium copper for reliable signal integrity.

Comparison with Similar Proximitor Sensors

When compared to earlier Proximitor Sensor designs, the 3300 XL series offers significant advantages. The 330180-50-00 provides improved RFI/EMI immunity, satisfying European CE mark approvals without requiring special shielded conduit or metallic housings. This reduces installation costs and complexity. Additionally, the SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen over time. Unlike some competing sensors that require separate isolator plates, the 3300 XL mounting base provides electrical isolation, simplifying installation and reducing hardware requirements.

Applications and Use Cases

The 330180-50-00 is ideal for non-contacting displacement measurements in rotating machinery. It accepts one 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable. Typical applications include steam turbine monitoring, compressor axial position measurement, and generator vibration analysis. Because of its high immunity to radio frequency interference, it can be installed in fiberglass housings without adverse effects from nearby RF signals. The wide operating temperature range of -52°C to +100°C ensures reliable performance in harsh industrial environments.

Installation and Integration

Installing the 330180-50-00 is straightforward due to its panel mount design and SpringLoc terminal strips. The sensor shares a 4-hole mounting footprint with older designs, allowing for direct replacement without drilling new holes. For nonincendive installations, follow installation drawing 140979. When integrating into existing machinery protection systems, ensure the power supply meets the specified voltage requirements. The sensor's output resistance of 50 Ω ensures compatibility with standard monitoring systems.
