Bently Nevada 330103‑00‑03‑05‑02‑05 Eddy‑Current Proximity Probe in stock

The Bently Nevada 330103‑00‑03‑05‑02‑05 belongs to the 3300 series eddy‑current proximity probe family. It applies eddy‑current sensing principle to convert clearance variation between probe tip and metal shaft into analog signal. Designed for non‑contact measurement of radial vibration, shaft displacement and thrust position on high‑speed rotating machinery. It must pair with matched extension cable and proximitor to build a complete transducer assembly for turbine and compressor TSI machinery‑protection loops.

This industrial proximity probe delivers stable gap‑voltage output with good temperature resistance and anti‑interference performance for harsh plant environments. It provides reliable raw sensing signals for 3500 series monitor modules. Manufactured in compliance with API 670 machinery‑protection requirements. Original production has been discontinued. It is widely available as aftermarket spare parts for sensor replacement, field maintenance and legacy monitoring‑system retrofitting projects.

FAQ

1. Q:Can 330103‑00‑03‑05‑02‑05 work as standalone unit?
   A:It must cooperate with matched extension cable and proximitor module, standalone probe cannot complete signal conversion and measurement.
2. Q:What symptoms appear upon probe failure?
   A:Unstable or abnormal gap‑voltage output, channel fault alarm on monitor module, loss of vibration and displacement data of corresponding channel.

3. Q:How to complete configuration and diagnosis?
   A:Check probe installation gap‑voltage on‑site, inspect cable connection status; carry out parameter verification via monitor module or System 1 software.
