Hardware Specifications

Gap Voltage and Transducer System Verification

The 330100-90-02 operates as part of a calibrated eddy-current transducer system. Correct matching of the probe, extension cable, and Proximitor Sensor is required to maintain specified signal scaling. During commissioning, gap voltage verification is commonly used to confirm proper probe-to-target positioning.

Frequently Asked Questions

Q: Can this sensor be used with any extension cable length?
A: No. The sensor should be installed with the cable configuration corresponding to the specified 9.0 m system length.

Q: What is the primary function of the Proximitor Sensor?
A: It converts eddy-current probe signals into proportional electrical outputs for monitoring equipment.

Field Installation Guidelines

• Route probe cables separately from power and motor cables.

• Maintain cable shield continuity according to site grounding practices.

• Verify probe, extension cable, and Proximitor Sensor compatibility before energization.

• Perform gap voltage validation after installation.
