Bently Nevada 330180-92-CN Proximitor Sensor Overview

The Bently Nevada 330180-92-CN is a 3300 XL Proximitor sensor made in the USA. This sensor accepts one non-contacting 3300-series 5 mm probe. In addition, it works with 3300 XL 8 mm proximity probes and extension cables. The 330180-92-CN incorporates numerous improvements over previous designs. For example, its physical packaging allows high-density DIN-rail installations. Alternatively, you can mount it in a traditional panel mount configuration. Specifically, it shares an identical 4-hole mounting footprint with older Proximitor sensor designs. As a result, retrofitting existing panels becomes very straightforward.

Technical Specifications

The Bently Nevada 330180-92-CN has a total system length of 9.0 meters (29.5 feet) . This length includes the probe, extension cable, and Proximitor sensor combined. The mounting option includes no mounting hardware. Agency approval option CN indicates country specific approvals. Therefore, check local requirements before installing this version.

Now consider the power requirements for this sensor. Specifically, the 330180-92-CN requires -17.5 Vdc to -26 Vdc input voltage. This applies when installed with a non-incendive circuit per drawing 140979. Maximum current consumption is 12 mA. When using barriers, the range becomes -23 Vdc to -26 Vdc. However, operation above -23.5 Vdc can reduce the linear range significantly. Supply sensitivity shows less than 2 mV change in output voltage per volt change. Finally, output resistance is 50 Ω for standard signal transmission.

Environmental & Temperature Range

The Bently Nevada 330180-92-CN operates in extreme temperature conditions. Specifically, operating temperature spans -52°C to +100°C (-62°F to +212°F) . Storage temperature ranges from -52°C to +105°C (-62°F to +221°F) . This wide range suits outdoor and harsh industrial environments. The Proximitor sensor material is A308 aluminum for durability. Connector material uses gold-plated brass or gold-plated beryllium copper. Consequently, these materials ensure reliable electrical connections over time.

RFI/EMI Immunity & Installation Benefits

The Bently Nevada 330180-92-CN demonstrates high immunity to radio frequency interference. In fact, you can install it in fiberglass housings without adverse effects. Nearby radio frequency signals will not disrupt measurements. Furthermore, the improved RFI/EMI immunity satisfies European CE mark approvals. Special shielded conduit or metallic housings are not required. As a result, installation costs and complexity are significantly lower.

The 330180-92-CN includes SpringLoc terminal strips for easy wiring. These require no special installation tools. Specifically, the SpringLoc design eliminates screw-type clamping mechanisms. Traditional screw clamps can loosen over time due to vibration. Therefore, SpringLoc provides faster and more robust field wiring connections.

Mounting & Electrical Isolation

The mounting base for the Bently Nevada 330180-92-CN provides built-in electrical isolation. Consequently, this eliminates the need for separate isolator plates. This feature saves both money and panel space. The 4-hole mounting footprint matches older Proximitor sensor designs perfectly. As a result, you can upgrade existing systems without drilling new holes. The 330180-92-CN fits both high-density DIN-rail and panel mount applications.

Key Features & Benefits

• Multiple mounting options – The 330180-92-CN fits DIN-rail or panel mount installations.

• Wide temperature range – Operates reliably from -52°C to +100°C.

• High RFI immunity – Install in fiberglass housings without shielded conduit.

• SpringLoc terminals – No special tools needed for fast, secure wiring.

• Electrical isolation – Built into mounting base, eliminating separate isolator plates.

• Compatible probes – Accepts both 3300-series 5 mm and 3300 XL 8 mm probes.

Installation Guidelines

Follow these steps to install the Bently Nevada 330180-92-CN correctly. First, mount the Proximitor sensor on DIN rail or a panel using the 4-hole footprint. Second, connect the 3300-series 5 mm or 3300 XL 8 mm probe to the input. Next, attach the extension cable between the probe and the 330180-92-CN if needed. Then, wire the power supply using SpringLoc terminals with -17.5 Vdc to -26 Vdc. After that, connect the output signal wires to your monitoring system. Finally, verify the total system length does not exceed 9.0 meters.

However, do not operate the 330180-92-CN above -23.5 Vdc when using barriers. Otherwise, this reduces the linear measurement range. Also, keep the probe tip at the recommended gap for best accuracy. Above all, use only Bently Nevada approved cables and probes with this sensor.
