Hardware Specifications

Rotor Dynamics And Eddy-Current Proximity Transducer Performance

The 3300 NSv Proximity Probe operates as a primary front-end sensor that utilizes high-frequency radio frequency signals to measure the physical gap between the probe tip and a conductive target surface. Proper system calibration relies on strict gap voltage validation, maintaining a target output of approximately -10 V DC when the shaft is centered within the linear operating range. This transducer design supports advanced rotor dynamics monitoring by delivering high-resolution signal scaling for small target measurements and restricted installation spaces. Signal integrity across the measurement loop depends heavily on maintaining clean coaxial connections, preventing ground loops, and utilizing matched extension cables to eliminate crosstalk and signal attenuation.

Ordering Information

• 1 x 330901-10-40-10-02-00 3300 NSv Proximity Probe (1/4-28 UNF thread, 1.0 in unthreaded length, 4.0 in case length, 1.0 meter cable with ClickLoc connector)

Field Installation Guidelines

• Mechanical Mounting: Thread the probe securely into the mounting hole utilizing standard 1/4-28 UNF threading, ensuring proper torque application to prevent thread stripping or mechanical loosening under high-vibration conditions.
• Gap Voltage Verification: Adjust the initial probe-to-target mechanical gap during installation until the static output voltage reaches the recommended operating window of -9 V to -11 V DC.
• Cable Routing: Keep the attached 1.0-meter coaxial cable routed away from high-voltage power lines, variable frequency drives, and heavy electromagnetic sources to prevent signal distortion.
• Connector Seating: Ensure the miniature coaxial ClickLoc connector is fully engaged and locked to prevent intermittent contact and spurious spike generation in the TSI monitoring system.

Frequently Asked Questions

• What is the primary function of the 330901-10-40-10-02-00 probe?
