Technical Dossier
The Bently Nevada 400100 Series Gap Proximitor Sensor is a precision eddy-current proximity transducer system designed for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in rotating machinery. Deployed across global heavy industry — including petrochemical refineries, nuclear power stations, offshore platforms, and LNG processing facilities — the 400100 Series forms a critical sensing layer within Bently Nevada's 3300 and 3500 machinery protection frameworks. Its field-proven architecture supports API 670 compliance requirements and is certified for use in hazardous area classifications including ATEX and IECEx zones. The series operates on the standard Bently Nevada proximitor signal conditioning principle: a probe tip generates a radio-frequency electromagnetic field; as a conductive target approaches, eddy currents are induced, altering the field impedance and producing a DC voltage output proportional to the gap distance. This output is directly compatible with 3300 and 3500 series monitor input cards without signal conversion.

Each 400100 Series unit processed by DriveKNMS undergoes a structured inspection and functional verification protocol specific to eddy-current proximity transducer systems. Verification steps include: DC output voltage linearity check across the full gap range (0–5mm or 0–10mm depending on variant) using a calibrated non-ferrous target fixture; oscillator frequency stability measurement at nominal supply voltage (−24 VDC); cable continuity and insulation resistance test at 500 VDC; connector pin integrity inspection under 10× magnification; and housing seal integrity check per IP67 criteria. For ATEX/IECEx-certified variants (400100-400 and 400100-500 sub-series), certification label legibility and entity parameter compliance are verified against the original certificate of conformity. Units that do not meet Bently Nevada factory output specifications are quarantined and not offered for sale.
