Hardware Specifications

Mechanical Monitoring and Signal Integrity

The 3300 XL system utilizes eddy-current probe scaling to convert target movement into precise voltage variations. Successful measurement depends on gap voltage validation; installers must verify that the probe tip is positioned within the linear -10 VDC target range at the Proximitor output. The design incorporates cross-talk suppression, enabling high-density sensor mounting while isolating vibration data from potential interference sources, which preserves the accuracy of shaft centerline and rotor dynamics analysis.

Field Installation Guidelines

• Mechanical Mounting

• Secure the probe using the fully threaded case design into a rigid mounting bracket to prevent resonant vibration coupling.

• Adjust the probe gap until the output voltage reaches the nominal -10 VDC setpoint at the monitor rack.

• Signal Cabling

• Utilize the ClickLoc connector for a high-integrity, vibration-proof link to the extension cable.

• Ensure the coaxial cable shield is grounded exclusively at the monitoring system's terminal block to prevent ground loops.

Frequently Asked Questions

• What is the function of the PPS probe tip?

  The polyphenylene sulfide (PPS) tip ensures dimensional stability and chemical resistance in harsh industrial environments, preventing signal drift due to material degradation.

• Can I shorten the integral 1.0 meter cable?

  No, the cable is a calibrated component of the transducer system; modifying its length alters electrical resonance and voids calibration accuracy.

• Why is the case fully threaded?

  The 2.5-inch fully threaded case provides maximum mounting flexibility in machines with varying clearance requirements and simplifies depth adjustment during installation.

• How do I confirm the probe is operating linearly?

  Perform a static gap check using a target material identical to the shaft; the Proximitor output must track within the defined linear -10 VDC operating range.

• Is the connector waterproof?

  The ClickLoc connector is designed for industrial use but requires proper installation and protection from direct liquid submersion to maintain contact integrity.

• Does this probe require maintenance?

  The probe is a solid-state, factory-sealed device. Maintenance is limited to periodic inspection of the probe tip for wear and verifying terminal connection tightness.

• Can this probe be used for speed measurement?

  Yes, the 0 to 10 kHz frequency response is sufficient for detecting keyway pulses or shaft features for speed and phase reference generation.

• How does thermal shift affect the signal?

  The 3300 XL design includes compensation to minimize temperature-induced signal variation, ensuring stable readings during machine warm-up and steady-state operation.
