Bently Nevada 330880/330881 Series Technical Notes

The Evolution of 330880/330881 Architecture

The 330880/330881 series was introduced as part of Bently Nevada's 3300 XL platform, succeeding the earlier 7200 and 3300 standard transducer families. The architectural shift addressed two primary industrial demands: extended temperature range operation and improved EMI immunity in high-noise plant environments. The 330880 variant is configured for standard 5-meter cable assemblies, while the 330881 accommodates extended cable lengths up to 9 meters, enabling installation flexibility in large-bore machinery trains where the monitor rack is remotely located.

330880/330881 Full Catalog & Functionalities (SKU List)

The following SKUs represent verified, commonly stocked models within the 330880/330881 proximity transducer family. Each entry reflects a specific cable length, connector, and temperature rating configuration:

330880-90-00: 5 m cable, standard temp, 8 mm probe, no connector
330880-90-05: 5 m cable, standard temp, 8 mm probe, armored cable
330880-90-00-05: 5 m cable, high-temp rated, 8 mm probe, bare end
330880-91-00: 5 m cable, standard, reverse-mount configuration
330880-91-05: 5 m cable, armored, reverse-mount, standard temp
330881-00-04-150-06-02: 9 m cable, 150 mm extension, standard temp, 8 mm probe — the reference SKU for this listing
330881-00-05: 9 m cable, armored, standard temp, 8 mm probe

Quality Control for the 330880/330881 Range

The 330880/330881 series presents specific test requirements due to its eddy-current signal chain architecture. Each unit processed by DriveKNMS undergoes the following verification protocol: (1) Static gap voltage test at nominal 1.0 mm, 1.5 mm, and 2.0 mm air gaps against a certified steel target to verify the 7.87 V/mm sensitivity curve within ±0.5% tolerance. (2) Cable continuity and insulation resistance test at 500 VDC to confirm no degradation in the coaxial cable assembly. (3) Frequency response check across the 0–10 kHz bandwidth to confirm flat response within the API 670 measurement band. (4) Connector integrity inspection for corrosion, pin alignment, and locking mechanism function. (5) Final comparison against a reference transducer on a calibrated Bently Nevada TK-3 or equivalent calibration fixture. Units that do not meet all five criteria are quarantined and not offered for sale.
