Product Overview

The Bently Nevada 330180-12-05 belongs to the 3300 XL Proximitor Sensor family. This sensor accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm Proximity Probe. An extension cable connects the probe to this Proximitor. Total system length reaches 1.0 meter (3.3 feet). This particular model includes no mounting hardware. Agency approvals include CSA, ATEX, and IECEx. The 330180-12-05 incorporates numerous improvements over previous designs. For example, physical packaging allows high-density DIN-rail installations. Alternatively, you can mount the sensor in a traditional panel mount configuration. The 4-hole mounting footprint matches older Proximitor designs. Consequently, retrofits and upgrades proceed smoothly.

Mounting Flexibility

The Bently Nevada 330180-12-05 offers two mounting configurations. High-density DIN-rail installation saves cabinet space. Traditional panel mounting uses the familiar 4-hole footprint. Older Proximitor designs share this exact mounting pattern. Therefore, upgrading existing systems requires no panel rework. The mounting base provides electrical isolation automatically. Separate isolator plates become completely unnecessary. For this reason, installation time and cost both decrease. The 330180-12-05 adapts to your preferred mounting method easily.

RFI/EMI Immunity

The 330180-12-05 demonstrates high immunity to radio frequency interference. Fiberglass housings cause no adverse effects on sensor operation. Nearby radio frequency signals do not corrupt measurements. Special shielded conduit becomes unnecessary for this sensor. Metallic housings are also not required. European CE mark approvals are satisfied without these extras. Consequently, installation costs drop significantly. System complexity reduces as well. The Bently Nevada 330180-12-05 performs reliably even in electrically noisy environments.

SpringLoc Terminal Strips

SpringLoc terminal strips distinguish the 3300 XL design. No special installation tools are required for wiring. Screw-type clamping mechanisms are completely eliminated. Those traditional screws can loosen over time from vibration. SpringLoc connections remain secure permanently. Field wiring connections become faster and more robust. For maintenance teams, this feature saves considerable time. The 330180-12-05 ensures reliable electrical contacts throughout its service life.

Input & Output Characteristics

A non-contacting probe connects to the Bently Nevada 330180-12-05. Compatible probes include 3300-series 5 mm and 3300 XL 8 mm types. An extension cable joins the probe to this Proximitor. Power requirements depend on your circuit configuration. Non-incendive circuits need -17.5 Vdc to -26 Vdc. Barriers require -23 Vdc to -26 Vdc. Operation above -23.5 Vdc may reduce linear range. Therefore, verify your power supply voltage carefully. Output resistance measures 50 Ω nominal. Supply sensitivity stays below 2 mV change per volt change.

Agency Approvals

The 330180-12-05 carries multiple hazardous area approvals. CSA certification covers North American installations. ATEX approval permits European Union use. IECEx certification satisfies international requirements. For global machine builders, these approvals prove essential. One sensor model serves many geographic markets. Procurement and inventory management simplify as a result.

Installation Guidelines

Follow these steps for proper installation of the 330180-12-05.

1. Select either DIN-rail or panel mounting based on your cabinet layout.

2. Mount the sensor securely using the 4-hole footprint or DIN clip.

3. Connect the 3300 XL 8 mm probe using the extension cable.

4. Wire the power supply observing correct polarity for -24 Vdc nominal.

5. Verify supply voltage stays within -23 Vdc to -26 Vdc for barrier applications.

6. Secure field wiring using the SpringLoc terminal strips. No screwdriver needed.

7. Power up the system and check output voltage for proper probe gap.

Note: The 330180-12-05 requires a clean, vibration-free mounting surface. Operation at voltages more positive than -23.5 Vdc may reduce linear range. Always consult the installation drawing 140979 for non-incendive circuit connections.

Common FAQs

1. What probes work with the 330180-12-05?

This Proximitor accepts 3300-series 5 mm proximity probes. It also accepts 3300 XL 8 mm proximity probes. An extension cable connects the probe to the 330180-12-05. Always use genuine Bently Nevada components for best performance.

2. What is the difference between the 05 approval option on the 330180-12-05?

The 05 option indicates CSA, ATEX, and IECEx approvals. These certifications allow hazardous area installation worldwide. Non-incendive circuit connections follow drawing 140979. For barrier installations, observe the -23 Vdc to -26 Vdc power range.

3. Can I mount the 330180-12-05 in a fiberglass enclosure?

Yes, the improved RFI/EMI immunity allows fiberglass housing use. Special shielded conduit becomes unnecessary. Metallic housings are also not required. CE mark approvals are satisfied without extra shielding. Consequently, installation costs remain lower than with older sensors.

4. What is the operating temperature range for the 330180-12-05?

Operating temperature spans -52°C to +100°C (-62°F to +212°F). Storage temperature reaches -52°C to +105°C (-62°F to +221°F). For this reason, the 330180-12-05 suits harsh industrial environments. Turbine monitoring and compressor protection applications work well within this range.

5. How do SpringLoc terminals improve wiring on the 330180-12-05?

SpringLoc terminals require no special tools for installation. Screw-type clamping mechanisms are eliminated entirely. Those screws can loosen from vibration over time. SpringLoc connections remain secure permanently. Field wiring therefore becomes faster, more robust, and more reliable.
