330180-12-00 Bently Nevada 3300 XL Proximitor Sensor 1.0m

What Is the 330180-12-00 Proximitor Sensor?

How can you achieve reliable, non-contact vibration measurement in harsh industrial environments without compromising signal integrity? The Bently Nevada 330180-12-00 3300 XL Proximitor Sensor answers this challenge with engineering-grade precision. As a key component in the 3300 XL series, this sensor converts signals from 3300-series 5 mm and 3300 XL 8 mm proximity probes and extension cables into precise voltage outputs. Its A308 aluminum housing and gold-plated brass or beryllium copper connectors ensure durability and stable performance. The 1.0 meter (3.3 feet) system length and no mounting hardware configuration suit high-density DIN-rail or traditional panel mount installations.

Key Specifications of the 330180-12-00

• Input Voltage: Requires -17.5 Vdc to -26 Vdc (non-incendive, 12 mA max) or -23 Vdc to -26 Vdc with barriers.
• Output Resistance: 50 Ω for consistent signal transmission.
• Isolation: Mounting base provides electrical isolation, eliminating separate isolator plates.
• Operating Temperature: -52°C to +100°C (-62°F to +212°F).
• Storage Temperature: -52°C to +105°C (-62°F to +221°F).
• Weight: 246 g (8.67 oz).
• Supply Sensitivity: Less than 2 mV output change per volt input change.

Note: Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range. The 330180-12-00 is highly immune to RFI/EMI, satisfying European CE mark approvals without special shielded conduit or metallic housings, which lowers installation costs and complexity.

Installation and Integration

Because the 330180-12-00 features SpringLoc terminal strips, field wiring is faster and more robust than screw-type clamps that can loosen. The sensor accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable. Its physical packaging supports high-density DIN-rail installations or a traditional panel mount with an identical 4-hole footprint to older Proximitor Sensor designs. The mounting base provides electrical isolation, so no separate isolator plates are needed. For precise matching, contact AutoDCSTech with your exact requirements.

Reliability and Maintenance

In terms of reliability, the 330180-12-00 operates effectively across a wide temperature range, from -52°C to +100°C, making it suitable for extreme industrial conditions. Its robust construction and RFI/EMI immunity reduce the risk of signal interference. Periodic inspection of connections and the probe gap is recommended to maintain measurement accuracy. Since the sensor uses SpringLoc terminals, verify that wires are properly seated during routine checks. For detailed maintenance procedures, refer to official Bently Nevada documentation.
