Hardware Specifications

Mechanical Monitoring and TSI Integration

Accurate rotor dynamics analysis requires consistent eddy-current probe scaling to maintain a linear output characteristic. The transducer must be installed such that the shaft target resides within the linear operating range, verified by target gap voltage validation; the standard -10 VDC operational midpoint is essential for preventing signal clipping. When multiple transducers are deployed, cross-talk suppression is achieved by maintaining specified spatial separation between probe tips and utilizing unique carrier frequencies to prevent inter-channel signal modulation and measurement inaccuracies.

Frequently Asked Questions

Q: Can I use this probe with a non-XL series Proximitor?

A: No, 3300 XL probes are calibrated for specific impedance matching with 3300 XL Proximitors; cross-series usage will result in severe non-linearity and calibration errors.

Q: How is the probe tip gap validated?

A: Gap validation is performed by measuring the DC output voltage of the Proximitor sensor while the machine is at rest; a target of -10 VDC is typically utilized to center the signal in the linear range.

Q: Is it possible to field-trim the coaxial cable length?

A: No, the transducer system (probe, cable, and Proximitor) is calibrated as a single matched unit; altering the cable length changes the system resonant frequency and voids calibration.
