Hardware Specifications

Rotor Dynamics And Eddy-Current Transducer Metrics

The transducer assembly relies on eddy-current probe scaling to measure displacement between the probe tip and the monitored metallic surface. Maintaining system integrity requires gap voltage validation targeting a -10 VDC nominal center point within a -9 V to -11 V DC linear operating envelope. Rotor dynamics analysis uses this high-frequency response to capture radial vibration and axial position changes on small shafts or restricted targets where standard 5 mm or 8 mm systems cannot physically fit.

Ordering Information

• 1 x 330910-01-08-50-01-05 3300 NSv Proximity Probe (M10X1 thread, armored build, 10 mm unthreaded length, 80 mm case length, 5.0 meters cable with ClickLoc connector and protector)

Field Installation Guidelines

• Thread Mounting: Screw the M10X1 threaded probe body into the prepared machine bore, observing correct depth and mechanical alignment.
• Torque Management: Tighten the probe housing securely to prevent shifting under continuous industrial vibration, avoiding over-torque limits that could damage threads.
• Air Gap Calibration: Adjust the mechanical gap relative to the target until the monitoring system reads the required -10 V DC initial offset voltage.
• Cable Routing: Keep the armored coaxial cable routed away from heavy power conduits to eliminate electrical noise interference.
• Connector Engagement: Push the miniature coaxial ClickLoc connector fully together until a distinct mechanical click verifies secure locking.

Frequently Asked Questions
