• Linear Range: 2.0 mm (80 mils), beginning at 0.25 mm (10 mils) from the tip.

• Scale Factor: 7.87 V/mm (200 mV/mil) via 3300 XL Proximitor interface.

• System Frequency Response: 0 to 10 kHz; +0, -3 dB.

• Operating Temperature: -51 °C to +177 °C (-60 °F to +351 °F).

• Probe Tip Material: High-performance Polyphenylene sulfide (PPS).

• Body Material: 300 series stainless steel.

• Cable Type: 75-ohm coaxial with FEP insulation.

• Connector Integrity: Gold-plated ClickLoc with 27 N (6 lbf) pull strength.

Typical Applications

As a core component of Machinery Condition Monitoring (MCM), the 330104-00-08-50-12-00 is deployed in high-speed industrial environments to prevent catastrophic failure:

• Radial Vibration: Measuring shaft dynamic motion within fluid-film bearings on turbines and pumps.

• Thrust Measurement: Monitoring axial position to detect thrust bearing wear or rotor movement.

• Keyphasor Signals: Providing once-per-turn timing pulses for phase angle and speed calculations.

• Eccentricity: Evaluating rotor bow or thermal warping during machine startup and coast-down sequences.
