Bently Nevada 330180-X1-CN is the 3300 XL proximitor (preamplifier) designed for 5 mm and 8 mm eddy‑current proximity probe systems, manufactured by Baker Hughes. This DIN‑rail mounted proximitor is the core signal conditioning unit of the transducer chain; it powers the probe, demodulates the eddy‑current signal and converts gap variation into a stable linear DC output for Bently Nevada 3500 TSI racks and other compatible monitoring instruments. The suffix CN stands for China market configuration with required local certification.

The 330180 proximitor works together with a matched proximity probe and extension cable. It supplies high‑frequency excitation to the probe coil, detects impedance shifts caused by changing metal target clearance, and outputs a voltage signal proportional to the gap between probe tip and shaft. This conditioned signal carries both static position information and dynamic vibration waveforms, supporting continuous machinery protection, alarm triggering and historical trending. It features improved temperature compensation and metallurgy tolerance compared to legacy 3300 non‑XL proximitors, delivering consistent measurement even when shaft material or surface finish varies.

Its compact blue housing supports standard DIN rail installation inside control cabinets, enabling dense, tidy layout for multi‑channel TSI setups. Built‑in fault detection monitors cable integrity, short circuits and open‑loop conditions; when wiring or probe failure occurs, the proximitor flags the fault to the monitor rack, helping engineers quickly locate broken cables, loose connectors or damaged probes before a false trip or loss of protection happens.

Common Applications

The Bently Nevada 330180-X1-CN proximitor is widely used in TSI and machinery protection systems for steam turbines, gas turbines, centrifugal compressors, high‑speed pumps, blowers and expanders. It is selected when the measurement loop uses 5 mm compact probes or standard 8 mm probes, typical for bearing vibration, thrust bearing position and shaft runout monitoring. Common sites include thermal power plants, combined‑cycle facilities, oil refineries, petrochemical complexes, LNG plants and offshore platforms. It is a popular spare part for loop retrofits, sensor system rebuilds and replacement of failed proximitors on existing 3300 XL installations.
