The Bently Nevada 330850-90-05, also cataloged as the 3300 XL 25 mm Proximitor Sensor, operates as a dedicated hardware interface for converting eddy-current probe displacement signals into conditioned voltage output within the 3300 monitoring system. It processes raw probe gap variation into a calibrated electrical signal proportional to shaft radial position.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Displacement Signal Processing

The 3300 XL proximity system uses eddy-current field interaction between probe tip and conductive target surface to derive displacement data. The proximitor converts probe coil impedance variation into a linearized voltage output referenced to calibrated gap conditions. Scale factor stability at 0.787 V/mm is maintained across the specified temperature range. Signal integrity is dependent on cross-talk suppression between adjacent channels and stable gap voltage validation near nominal -10 VDC operating reference behavior in associated probe driver circuitry.

Frequently Asked Questions

Q: Does the 330850-90-05 support 3300 XL probe interchangeability?
A: It is designed for compatibility with 3300 XL 25 mm proximity probe systems within defined calibration ranges.

Q: What is the function of the 9.0 m system length specification?
A: It defines the maximum integrated cable distance between probe, extension cable, and proximitor sensor.

Q: Can the sensor operate under high-temperature conditions continuously?
A: The module is rated for operation up to +100 deg C with defined thermal drift characteristics.

Q: Does the system require external calibration after installation?
A: Calibration is factory-set; field verification may be performed using standard gap reference targets.

Field Installation Guidelines

• Install panel-mounted proximitor on stable grounded metal surface
• Maintain separation between probe cable and high-voltage conductors
