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.
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.
