Mechanical Monitoring and TSI Characteristics

The 330878-90-00 utilizes eddy-current probe scaling to convert the distance between the probe tip and a metallic target into a proportional electrical signal. During commissioning, installers must perform gap voltage validation to confirm a -10 VDC target, which ensures the device is operating at the center of its linear range for optimal fidelity in rotor dynamics observation. In configurations utilizing multiple sensors, cross-talk suppression is achieved by maintaining strictly defined spacing between adjacent probe tips, preventing inductive interference within the oscillator circuit.

Frequently Asked Questions

Q: Is it permissible to field-modify the 9.0 meter coaxial cable length?

A: No. The 3300 XL Proximitor system is factory-calibrated as an integrated assembly (probe, extension cable, and Proximitor). Any physical alteration to the system length will result in calibration drift and measurement errors.

Q: How is the Proximitor grounded within the monitoring cabinet?

A: The Proximitor chassis must be bonded to the cabinet ground to establish a common reference potential and ensure effective electromagnetic shielding.

Field Installation Guidelines

Mount the Proximitor to a metal panel using the integrated holes, ensuring direct contact with the panel for chassis grounding.
Route signal cabling through rigid, shielded conduit to minimize the risk of RFI/EMI noise injection from high-voltage AC lines.
Tighten all BNC-style coaxial connectors until finger-tight; do not use pliers or other mechanical tools to prevent damage to the connector dielectric.
Verify that the probe tip is installed perpendicular to the shaft target to prevent measurement artifacts caused by radial runout.
Terminate the signal shield at the monitoring instrument end only to mitigate the formation of ground loops in the field wiring.
