Hardware Specifications

Eddy-Current Probe System Matching

The 330100-90-05 operates as part of a calibrated transducer system consisting of a proximity probe, extension cable, and Proximitor Sensor. Proper matching of system components is required to maintain specified signal scaling and measurement accuracy. Gap voltage verification is typically performed during commissioning to confirm correct probe positioning relative to the target surface.

Frequently Asked Questions

Q: Can this unit be used with extension cables of different lengths?
A: The sensor should be installed with components corresponding to the specified 9.0 m transducer system configuration.

Q: What is the primary function of the Proximitor Sensor?
A: It converts eddy-current probe signals into electrical outputs used by machinery monitoring systems.

Field Installation Guidelines

• Route transducer cables away from power and motor conductors.

• Maintain shield continuity according to site grounding practices.

• Verify compatibility between the probe, extension cable, and Proximitor Sensor before installation.

• Perform gap voltage checks before placing the monitored machine into service.
