Gap Voltage Validation (-10 VDC Targets) & Eddy-Current Probe Scaling

The module conditions raw excitation signals received from a 3300 NSv non-contacting proximity probe across a tuned system length. Field commissioning requires gap voltage validation across the non-isolated PROX OUT and COM terminals to establish the baseline target at -10 VDC when the shaft rotor is centered in its axial float clearance. Precise eddy-current probe scaling converts minute axial target shifts into a proportional 4-20 mA loop signal for direct transmission to process monitors and PLC hardware.

Frequently Asked Questions

Q: Does the transmitter require a secondary external Proximitor Sensor unit to function?

A: No, the module incorporates an integrated Proximitor sensor circuit directly within its compact housing, eliminating the requirement for separate external signal conditioning modules.

Q: How can field engineers observe dynamic probe signals without disturbing loop wiring?

A: Test connections can be made directly across the non-isolated PROX OUT and COM terminals to read the raw dynamic vibration waveform and static DC gap voltage using standard diagnostic tools.

Q: What proximity probe series is compatible with this unit?

A: The input signal interface is specifically calibrated for connection to a Bently Nevada 3300 NSv proximity probe and matching extension cable assembly.

Field Installation Guidelines

Mount the compact transmitter module securely inside a protective panel or junction box using standard mounting fasteners.
Connect the 3300 NSv proximity probe extension cable coaxial connector to the transmitter input jack, securing the coupling finger-tight.
Validate static DC gap voltage using a multimeter across the PROX OUT and COM terminals, adjusting mechanical probe depth until the -10 VDC target offset is obtained.
Wire the 2-wire loop terminals to the 24 VDC powered analog input channel of the control system.
Terminate the overall cable shield to the cabinet earthing bus bar at a single ground point to eliminate ground loops and field interference.
