Mechanical Monitoring and TSI Characteristics

The 330850-91-05 utilizes eddy-current probe scaling to convert the gap between the probe tip and a metallic target into a proportional electrical signal. During commissioning, technical personnel must perform gap voltage validation, targeting a -10 VDC nominal reading to ensure the sensor operates at the center of its linear range. Precise calibration is required to support accurate rotor dynamics analysis. In arrays involving multiple sensors, cross-talk suppression must be addressed through proper physical spacing of the probe tips to prevent frequency interference within the monitoring circuit.

Frequently Asked Questions

Q: Can the 9.1 meter system length be modified in the field?

A: No. The 3300 XL system is a calibrated unit consisting of a specific probe, extension cable, and Proximitor. Modification of the total system length will invalidate the calibration and cause significant measurement errors.

Q: What is the purpose of the gap voltage check?

A: The gap voltage check verifies that the sensor is installed at the proper distance from the target, ensuring that the output signal remains within the linear operating range during normal shaft motion.

Field Installation Guidelines

Mount the Proximitor to a grounded DIN-rail to ensure a stable reference potential and electromagnetic shielding.
Ensure coaxial cable routing is physically isolated from AC power or motor drive cables to prevent electromagnetic noise induction.
Tighten all coaxial BNC connections until finger-tight; excessive mechanical torque can damage the internal ceramic dielectric.
Verify the probe-to-target alignment is strictly perpendicular to the rotating shaft surface to avoid runout measurement artifacts.
Terminate the signal shield at the monitor end only to prevent ground loop currents in the field wiring.
