Hardware Specifications

Mechanical Monitoring and Signal Validation

The Proximitor sensor acts as the radio-frequency excitation source for the eddy-current probe. It converts the impedance change of the probe tip into a linear voltage signal. Signal accuracy depends on gap voltage validation; the system is typically configured to provide a -10 VDC output at a reference gap of 1.27 mm. Rotor dynamics data integrity is maintained by ensuring the total system length (probe + extension cable + Proximitor) remains matched to the factory calibration. Cross-talk suppression is maintained when the Proximitor is installed in a grounded enclosure, preventing electromagnetic interference from contaminating the low-level signal output.

Frequently Asked Questions

• Q: Can this unit be used with 8 mm probes?

  A: Yes, the 330180 Proximitor is designed to interface with standard 3300 series 8 mm probes.

• Q: What is the purpose of the 145004-81 modification code?

  A: This code denotes a factory-specified variation to the standard 330180 circuitry, often related to specific impedance or response curve requirements.

• Q: Does the Proximitor require an external power supply?

  A: Yes, it requires a regulated -17.5 to -26 VDC power supply input.

• Q: Can I mix different system lengths?

  A: No, the system calibration is dependent on the total length of the probe and extension cable; changing the length will alter the scale factor.

• Q: Is this sensor hot-swappable?

  A: It is recommended to remove power before disconnecting the sensor to prevent signal transients.

• Q: What is the signal output range?

  A: The output is typically proportional to the distance at -200 mV/mil.

• Q: How do I test if the Proximitor is functional?

  A: Measure the output voltage at the signal terminals while using a calibration target to verify the -10 VDC setpoint.

• Q: Is the DIN mount removable?

  A: The DIN mounting clip is integral to the housing design for vibration stability.
