Technical Parametric Data

Rotor Dynamics and Gap Voltage Validation

The probe employs high-frequency eddy-current fields to track high-speed rotor dynamics without mechanical contact. To establish accurate steady-state operation within the linear range, the field engineer must execute a physical gap voltage validation. Adjusting the probe's mechanical position relative to the target surface yields a baseline target value of -10.0 VDC at the Proximitor output terminal. This value represents the geometric center of the linear sensor slope. Proper installation pitch ensures optimal signal-to-noise ratios during high-amplitude shaft vibrations and prevents measurement saturation near the physical extremities of the probe's eddy-current field.

Field Installation Guidelines

Mechanical installation requires precise physical alignment to ensure the eddy-current field is not constrained. The probe tip must clear surrounding counterbore walls by a minimum diameter of 16 mm to avoid side-wall cross-talk and calibration errors. Use a calibrated handheld digital multimeter to monitor the DC gap voltage in real-time while threading the probe into its mounting bracket. Once the -10.0 VDC target voltage is logged, secure the M10 locknuts to the specified torque limit to prevent backing out during high-frequency machine operation. The miniature coaxial ClickLoc connector must be clean, dry, and clicked firmly together before being sealed inside the fluid-resistant boot. All field extension cabling must track through dedicated, grounded metal conduit, respecting a minimum bend radius of 25.4 mm.

Logistic and Freight Specifications

Delivery time: 2-7 days when payment finish, handled exclusively through DHL/FEDEX/UPS express networks. Hardware is shipped inside heavy-duty anti-static industrial packaging containing multi-layered ESD shielding film and customized structural low-density polyethylene foam cells to isolate the ceramic tip assembly and the flexible 0.5-meter coaxial cable from mechanical impact and transient electrostatic discharge during air transit.

Frequently Asked Questions

Q: What happens to the proximity measurement if the target shaft material is not AISI 4140 steel?

A: The eddy-current probe scaling will shift because different alloys have distinct magnetic permeability and electrical conductivity profiles. This change alters the standard 7.87 V/mm scale factor, requiring laboratory recalibration or monitoring software compensation curves.

Q: Can this 0.5-meter total length probe connect directly to a TSI monitor panel without an extension cable?

A: No. The 3300 XL 8 mm proximity probe requires a matching extension cable to construct a complete electrical resonant loop. The combined length of the probe and extension cable must precisely equal the 5.0-meter or 9.0-meter specifications mandated by the Proximitor Sensor model in use.

Q: Will disconnecting the ClickLoc connector while the monitor loop is energized damage the probe?

A: No physical damage occurs to the passive probe element during a live disconnect. However, breaking the coaxial connection causes an immediate open-circuit state, driving the Proximitor output to a positive saturation voltage, which triggers a "Not OK" fault condition on the safety monitor module.
