Bently Nevada 330878-90-05 3300 XL 50 mm Proximitor Sensor

Configured for eddy-current proximity signal conditioning in the Bently Nevada 3300 XL machinery protection system, the Bently Nevada 330878-90-05 (330878 Proximitor Sensor) provides direct electrical execution. The assembly converts the probe signal for transmission to the associated monitoring system while maintaining the specified 9.0 m system length and panel-mount configuration.

Gap Voltage Validation

The 3300 XL measurement chain is intended to operate with a matched eddy-current probe, extension cable, and Proximitor Sensor using the specified system length. During commissioning, gap voltage should be verified after mechanical installation. For Bently Nevada eddy-current systems, technicians commonly validate the static probe position against the expected gap voltage target, typically near -10 VDC when the mechanical installation permits. Final acceptance should always follow the applicable system documentation for the installed probe configuration.

Frequently Asked Questions

Q: Can this Proximitor Sensor be installed with a different system cable length?
A: The sensor should be used with the specified matched probe and extension cable assembly corresponding to the defined 9.0 m system length. Mixing unmatched cable lengths can affect calibration and measurement accuracy.

Q: Does the supplied information indicate hot-swap capability?
A: No. The provided documentation does not specify hot-swap support. Installation or replacement should follow the maintenance procedure defined for the associated monitoring system.

Q: Why is shield grounding important for this sensor?
A: Proper cable shielding and grounding reduce electrical noise and help minimize signal interference between adjacent proximity measurement channels.

Field Installation Guidelines

• Verify that the installed probe, extension cable, and Proximitor Sensor belong to the same calibrated system length.
• Mount the Proximitor Sensor securely on the designated panel to prevent vibration-induced cable movement.
• Route proximity cables separately from high-voltage and motor power conductors whenever practical.
• Maintain cable shielding in accordance with the installation manual and avoid multiple unintended shield grounding points.
• Confirm probe gap voltage after mechanical alignment before placing the monitoring channel into service.
