Hardware Specifications

Rotor Dynamics And Eddy-Current Probe Scaling

The transducer assembly utilizes eddy-current probe scaling to map physical air gap clearances into proportional analog voltage signals. Proper system operation mandates strict gap voltage validation targeting a nominal center point between -9 VDC and -11 VDC. Rotor dynamics analysis relies on this high-frequency response to track displacement and vibration, supported by matched impedance cabling and cross-talk suppression to maintain signal fidelity across industrial monitoring loops.

Ordering Information

• 1 x 330904-00-25-05-02-CN 3300 NSv Proximity Probe Assembly (M8x1 thread, 250 mm case length, 0.5 meter standard cable, miniature coaxial ClickLoc connector)

Field Installation Guidelines

• Thread Engagement: Screw the M8x1 probe housing carefully into the machinery mounting port, utilizing proper thread engagement to avoid mechanical binding.
• Gap Voltage Verification: Calibrate the physical air gap clearance until the connected monitor registers a static gap voltage between -9 VDC and -11 VDC.
• Lead Routing: Route the coaxial cable away from high-voltage power conduits and alternating current lines to prevent induced electromagnetic noise.
• Connector Locking: Engage the miniature coaxial ClickLoc connector fully until a positive latching action secures the connection against vibration.
