Product Overview

The Bently Nevada 330180-91-CN is a 3300 XL Proximitor Sensor. This sensor incorporates numerous improvements over previous designs.

Its physical packaging allows you to use it in high-density DIN-rail installations. You can also mount the sensor in a traditional panel mount configuration. The panel mount option shares an identical 4-hole mounting "footprint" with older Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates.

Key Features

The 330180-91-CN offers several advantages for proximity measurement.

High-Density DIN Rail Mounting:
The physical packaging allows high-density DIN-rail installations. This saves valuable cabinet space.

Traditional Panel Mount Compatibility:
Shares an identical 4-hole mounting footprint with older Proximitor Sensor designs. Therefore, retrofitting existing installations is simple.

Integrated Electrical Isolation:
The mounting base for either option provides electrical isolation. Consequently, separate isolator plates are not required.

Improved RFI/EMI Immunity:
The 3300 XL Proximitor Sensor is highly immune to radio frequency interference. You can install it in fiberglass housings without adverse effects from nearby radio frequency signals. This improved immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings. As a result, installation costs and complexity are lower.

SpringLoc Terminal Strips:
These terminal strips require no special installation tools. They eliminate screw-type clamping mechanisms that can loosen. Therefore, they facilitate faster, more robust field wiring connections.

Wide Temperature Range:
Operates from -52°C to +100°C. Storage temperature extends to +105°C. Hence, the sensor suits extreme climate conditions.

Typical Applications

The 330180-91-CN suits various turbomachinery monitoring applications.

• Radial vibration monitoring on steam turbines with DIN rail mounting.

• Axial position measurement on gas compressors in high-density cabinets.

• Shaft eccentricity monitoring on hydro turbines.

• Differential expansion measurement on large rotating equipment.

• Thrust position monitoring where the 4-hole panel mount footprint is required for retrofit.

Installation Guidelines

Install the 330180-91-CN according to standard 3300 XL proximity system practices. Mount the sensor on a DIN rail for high-density installations. Alternatively, use the 4-hole panel mount pattern for retrofitting existing panels.

Power Connections:
Connect power at -17.5 Vdc to -26 Vdc for non-incendive circuits. For installations with intrinsic safety barriers, use -23 Vdc to -26 Vdc. Ensure the voltage does not exceed -23.5 Vdc positive side to avoid reduced linear range.

Field Wiring:
The SpringLoc terminal strips accept simple wire insertion. No special tools are required. The terminals eliminate screw-type mechanisms that can loosen over time.

Probe Connection:
Connect a 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable to the sensor input. The system length is 9.0 meters.
