Technical Data Specifications

Rotor Dynamics and Gap Voltage Validation

The 3300 XL transducer system utilizes high-frequency radio frequency modulation to gauge physical spacing between the probe tip and rotating machine components. System linearity depends on strict gap voltage validation, establishing a baseline target of -10 VDC during centerline machine operation. Eddy-current probe scaling maps structural variations across carbon steel shafts into precise electrical potentials. Adequate cross-talk suppression is achieved by maintaining required minimum spatial intervals between adjacent probe tips to eliminate mutual electromagnetic interference in dual-plane monitoring arrays.

Site Installation Procedures

• Mechanical Mounting Practice
  • Clean machine casing threads thoroughly to eliminate contamination before inserting the probe housing.
  • Apply controlled torque via calibrated tools to secure the probe body without inducing mechanical thread distortion.
• Wiring and Shield Grounding
  • Keep coaxial extension lines away from high-voltage AC power pathways and motor inverter outputs.
  • Terminate the signal shield exclusively at the instrument rack ground terminal to prevent ground loops.

Technical FAQs

• Q: What output scale factor does this proximity probe deliver?
• A: The nominal incremental scale factor is 7.87 V/mm (200 mV/mil) when matched with a compatible Proximitor sensor.
• Q: What is the maximum continuous temperature rating for the probe tip?
• A: The probe tip and integral cable tolerate continuous operating environments up to +177 deg C.
• Q: What gap voltage level is targeted during initial probe calibration?
• A: Initial mechanical gap voltage should be tuned to approximately -10 VDC to center the operating range.
• Q: Do the ClickLock connectors require special installation wrenches?
• A: No, these connectors are designed for secure hand-tightened installation with positive tactile feedback.
• Q: What thread standard does the probe case feature?
• A: It utilizes standard 3/8-24 UNF threading for mounting into machinery bearing housing ports.
• Q: How does total electrical cable length influence system performance?
• A: Total electrical length requires matching Proximitor calibration to maintain precise signal impedance and linearity.
• Q: What power supply drives the transducer loop?
• A: A regulated -24 VDC power source integrated within the monitor rack powers the measurement circuit.
• Q: Why is single-point grounding mandatory for the coaxial shield?
• A: Single-point grounding suppresses high-frequency electromagnetic noise and prevents ground loop interference.
