Eddy-Current Probe Scaling and Signal Validation

The 330878-91-05 Proximitor sensor is calibrated to interface with 50 mm proximity probes, translating target surface displacement into a proportional voltage signal. Achieving accurate measurement requires strict gap voltage validation; the sensor should output a nominal -10 VDC when the probe is positioned at the center of its linear range relative to the target material. To preserve the integrity of the data stream, cross-talk suppression must be implemented in the field by ensuring that adjacent sensors are spaced according to manufacturer-specified distances to prevent electromagnetic interference between high-frequency oscillator signals.

Frequently Asked Questions

Q: Is this sensor compatible with all 3300 XL series extension cables?

A: Compatibility is dependent on the total system length. The 330878-91-05 is calibrated for a specific system length; using an extension cable that deviates from this specified length will cause significant errors in the voltage-to-distance transfer function.

Q: Can this unit be hot-swapped while the machinery is in operation?

A: The Proximitor sensor can be disconnected, but doing so will trigger an open-circuit fault in the connected monitor module. Ensure the monitoring system is placed in "Bypass" or "Inhibit" mode before performing any maintenance on the sensor connections.

Field Installation Guidelines

Mount the sensor in an environment protected from mechanical impact and excessive heat.
Ensure the coaxial cable shield is properly terminated at the monitoring rack common to prevent common-mode noise injection.
Keep the cable run away from high-current power cabling to avoid electromagnetic noise pickup.
Verify all BNC or terminal block connections are secure to prevent intermittent signal dropouts caused by vibration.
Perform a gap voltage check using a multimeter at the monitor input terminals after final installation to confirm the -10 VDC baseline at the mechanical center.
