Description

Technical Overview

The Bently Nevada 330104-12-20-10-02-00 is a high-precision, industrial-grade proximity transducer belonging to the renowned 3300 XL family of eddy-current sensing systems. Manufactured by Baker Hughes (formerly Bently Nevada), this 8 mm diameter sensor delivers exceptional linearity, temperature stability, and electromagnetic interference (EMI) immunity for mission-critical machinery protection and condition monitoring applications. Engineered to meet stringent API 670 (4th and 5th Editions) and ISO 10816 standards, the transducer operates on the principle of high-frequency eddy-current displacement measurement—detecting minute changes in the gap between the probe tip and conductive target surfaces with sub-micron resolution. Its robust stainless steel construction, hermetically sealed ceramic insulator, and integrated coaxial cable ensure long-term reliability in harsh environments characterized by extreme temperatures (–30 °C to +120 °C ambient), high vibration, oil immersion, and aggressive chemical exposure. The 330104-12-20-10-02-00 is designed exclusively for use with Bently Nevada 3300 XL series monitors—including the 3300/16, 3300/22, and 3500 system platforms—and requires calibration against its matching extension cable and monitor channel to achieve factory-specified accuracy. As a new, unused OEM product, it ships in original factory packaging with full traceability documentation and complies with RoHS, CE, and ATEX directives where applicable. This transducer is ideal for users seeking plug-and-play compatibility, repeatable performance across decades of service life, and seamless integration into enterprise-wide asset health management ecosystems.

Detailed Specifications

Key Features

• OEM-Exact Calibration & Traceability: Delivered with NIST-traceable calibration certificate and individual serial-numbered calibration data, ensuring compliance with API 670 verification requirements and eliminating field recalibration delays.
• Enhanced Environmental Resilience: Hermetically sealed ceramic tip and PTFE-insulated coaxial cable provide superior resistance to moisture ingress, oil saturation, thermal shock, and corrosive hydrocarbons—validated per MIL-STD-810G environmental testing protocols.
