Hardware Specifications

Mechanical Monitoring & TSI Properties

The transducer assembly utilizes eddy-current probe scaling to translate target proximity into a linear voltage signal. System accuracy is contingent upon rigorous gap voltage validation to maintain -10 VDC targets under nominal operating conditions. During installation, technicians must account for rotor dynamics to minimize signal distortion, and ensure adequate cross-talk suppression by maintaining spatial isolation from adjacent high-frequency sensing elements within the machine casing.

Field Installation Guidelines

• Mounting: Install the probe into the mounting bracket via the 3/8-24 UNF thread; ensure thread engagement is sufficient to provide structural stability without impacting the target.
• Gap Setting: Adjust the transducer air gap to align with the required voltage offset, verifying the output with a high-impedance voltmeter.
• Grounding: Ensure electrical continuity between the probe housing and the machine chassis as required by the monitoring system's grounding scheme.
• Cabling: Secure the 5.0 meter coaxial cable using appropriate clamps to prevent mechanical fatigue and avoid routing alongside high-voltage power lines.

Frequently Asked Questions

• What is the significance of the 0.3 in case length?

  The case length defines the physical envelope of the probe body; this short length is suitable for installations where mounting space is restricted.

• How does the 5.0 meter cable length affect calibration?

  The system is calibrated for a specific total length; the 5.0 meter length is the standard system length for which the Proximitor sensor impedance is matched.

• Are these probes compliant with hazardous area requirements?

  Yes, the model includes CSA, ATEX, and IECEx approvals, permitting operation in designated explosive atmospheres when installed per control drawings.

• What is the impact of excessive gap voltage?

  Voltage readings significantly offset from the -10 VDC target may indicate a misaligned probe or an approaching limit of the linear operating range.

• Can this probe monitor axial position?

  Yes, the probe provides linear displacement data suitable for both radial vibration and axial thrust position measurements.

• How should the ClickLoc connector be handled?

  The connector should be kept free of dirt and oil; use the supplied protector during installation to prevent contamination of the mating surfaces.

• Is backward compatibility supported?

  The 3300 XL probe is compatible with legacy 3300 series transducer systems, though complete XL performance features require the full XL system configuration.

• What measures prevent signal cross-talk?

  Maintain minimum spacing between adjacent probe tips as specified in the installation manual to prevent electromagnetic signal beating between sensors.
