Technical Dossier
The 22810 Series was introduced as part of Bently Nevada's standardized eddy-current probe ecosystem, designed to interface directly with the 3300 XL 8mm Proximity Transducer System and the 7200 Series driver/extension cable assemblies. Early variants used a fixed-frequency oscillator driver architecture operating at 200 kHz, optimized for AISI 4140 steel targets. Subsequent revisions introduced tighter gap voltage linearity tolerances (±0.5% over the calibrated range), improved high-temperature cable jacketing (rated to 175°C), and armored conduit-compatible connector bodies.
The 22810 probe body is constructed from 316L stainless steel with a PEEK (polyether ether ketone) tip for chemical resistance. Cable assemblies are available in standard lengths of 0.5 m, 1.0 m, 1.5 m, and 2.0 m, with extension cables (3300 XL series) bridging the probe to the driver/monitor rack. The system operates on the standard Bently Nevada gap voltage convention: –24 VDC supply, nominal gap output of –10.4 VDC at 2.0 mm gap (8 mm probe). As the 3300 XL platform has entered its mature/sustaining lifecycle phase, Bently Nevada's current recommended migration path for new installations is the 3500 Series with compatible 190500 or 330780 probes; however, the 22810 Series remains fully supported for existing installations and spare parts procurement.
The following SKUs represent verified, commonly stocked configurations within the Bently Nevada 22810 Proximity Probe family. Each probe designation encodes body length, cable length, connector type, and temperature rating per Bently Nevada's standard part numbering convention.

All units are cross-referenced against Bently Nevada's original part number matrix to confirm compatibility with 3300 XL drivers (e.g., 330180, 330130) and extension cables (e.g., 330130-045-00-00). Customers operating aging DCS or machinery protection systems who require like-for-like replacements without system reconfiguration are the primary beneficiaries of this sourcing capability. DriveKNMS also supports bill-of-materials (BOM) matching for plant turnaround and shutdown projects requiring multiple 22810 variants simultaneously.
Each 22810 Series probe processed through DriveKNMS undergoes a structured inspection and functional verification protocol prior to shipment. The procedure addresses the specific failure modes associated with eddy-current proximity transducers: tip delamination, cable jacket cracking, connector pin corrosion, and oscillator frequency drift.
Inspection steps include: (1) visual examination of probe tip, body, and cable jacket for mechanical damage; (2) DC resistance measurement of the probe coil (reference: 4.5–5.5 Ω for standard 8mm probes); (3) functional gap-voltage linearity test using a calibrated steel target plate and a reference 3300 XL driver, verifying output within ±1% of the Bently Nevada calibration curve across the 0.25–2.54 mm gap range; (4) connector continuity and insulation resistance test (≥100 MΩ at 500 VDC); (5) cable flex test at the probe-to-cable junction, the highest-stress mechanical point. Units that do not meet all acceptance criteria are quarantined and not offered for sale.
