Mechanical Monitoring and TSI Characteristics

The 330850-90-05 utilizes eddy-current probe scaling to convert the gap between the probe tip and the observed shaft into a proportional electrical signal. During commissioning, operators must perform gap voltage validation to ensure the steady-state reading is centered at -10 VDC, optimizing the linear range for dynamic observation of rotor dynamics. To maintain measurement precision, particularly in multi-probe arrays, cross-talk suppression must be implemented by strictly adhering to installation spacing guidelines to prevent inductive interference between adjacent sensors.

Frequently Asked Questions

Q: How should the probe gap be verified during initial installation?

A: Using a high-impedance digital multimeter, measure the voltage at the Proximitor signal output terminals while the machine is at rest. Adjust the probe depth until the voltage reaches the -10 VDC target, confirming the sensor is at the center of its linear range.

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

A: No. The 3300 XL system is factory-calibrated as a complete assembly (probe, extension cable, and Proximitor). Altering the system length will invalidate the calibration and introduce significant measurement errors.

Field Installation Guidelines

Mount the Proximitor to a metal panel, ensuring a high-integrity electrical bond to the cabinet chassis for effective EMI shielding.
Route coaxial cabling through rigid, grounded conduit; maintain segregation from high-voltage AC lines to minimize signal noise.
Verify that all coaxial connectors are tightened to finger-tight. The use of pliers can result in damage to the connector dielectric.
Ensure the probe tip is installed perpendicular to the shaft target to avoid measurement bias caused by radial runout or non-planar surfaces.
Terminate the shield at the monitor end only to prevent ground loops within the signal circuit.
