Overview
Configured for conductive-target position measurement in a Bently Nevada eddy-current proximity sensing chain, the Bently Nevada 330106-05-30-05-02-CN (330106 reverse mount proximity probe) provides non-contact measurement of static position and dynamic vibration. It uses a 0.5 m probe length, M10 x 1 case thread, PPS tip, and 75 ohm triaxial FEP-insulated cable.

Eddy-Current Probe Scaling and Gap Voltage
The 330106-05-30-05-02-CN operates as the probe element in an eddy-current displacement measurement chain. The probe senses changes in the electrical field caused by a conductive target, while the matching Proximitor Sensor converts the probe response into the system output used for position and vibration monitoring.
For installation, the probe, extension cable, and Proximitor Sensor must form the specified sensing configuration. The installed gap should follow the applicable system calibration requirements. Verify the probe thread, cable configuration, connector arrangement, and target material before commissioning.
Frequently Asked Questions
Q: What mounting configuration does 330106-05-30-05-02-CN use?
A: It uses a reverse-mount configuration with an M10 x 1 case thread.
Q: What cable construction does this probe use?
A: The probe uses 75 ohm triaxial cable with FEP insulation. The specified configuration has no armor and uses a standard cable without a connector protector.
Q: What temperature range does the probe specify?
A: The specified operating and storage range is -52 to +177 deg C.
Field Installation Guidelines
Install the probe using the specified reverse-mount arrangement and verify full M10 x 1 thread engagement without applying excessive mechanical force. Keep the probe cable routed away from high-current conductors and strong electrical noise sources where practical.
Maintain the cable’s shielding and termination arrangement specified for the complete sensing system. Avoid sharp bends, crushing, or excessive tensile loading on the triaxial cable. Before operation, verify the probe, extension cable, Proximitor Sensor, connector configuration, and calibration combination as one complete measurement chain.
