Hardware Specifications

Rotor Dynamics And Eddy-Current Probe Scaling

The transducer assembly utilizes eddy-current probe scaling to convert physical gap spacing into proportional analog signals, yielding an average scale factor of 7.87 V/mm (200 mV/mil). Achieving accurate rotor dynamics tracking requires strict gap voltage validation targeting a nominal center point between -9 VDC and -11 VDC. Matched impedance cabling and cross-talk suppression preserve high-frequency signal fidelity throughout the monitoring loop.

Ordering Information

• 1 x 330904-00-05-70-01-05 3300 NSv Proximity Probe (M8x1 thread, armored cable, 7.0 meters total length, miniature coaxial ClickLoc connector, connector protector)

Field Installation Guidelines

• Thread Alignment: Thread the M8x1 probe housing carefully into the machinery mounting port, avoiding cross-threading or mechanical binding.
• Gap Voltage Verification: Adjust the air gap clearance until the connected monitor registers a static gap voltage between -9 VDC and -11 VDC.
• Shielding and Routing: Route the armored cable away from alternating current power lines to prevent electromagnetic interference.
• Connector Locking: Engage the ClickLoc connector fully until a positive latching action secures the connection against vibration.

Frequently Asked Questions

• What is the primary function of the 330904-00-05-70-01-05 probe?

  It detects physical displacement and shaft vibration by measuring the air gap between its tip and a conductive target surface.

• What thread standard does this probe utilize?

  The housing features an M8x1 mounting thread configuration.

• Does this sensor require an external power source?

  No, it operates as a passive inductive component powered exclusively by its paired Proximitor sensor unit.

• What is the total length of the integrated cable?

  This configuration includes a total cable length of 7.0 meters (23.0 feet).

• What output scale factor does the NSv system maintain?

  The transducer outputs an average scale factor of 7.87 V/mm (200 mV/mil).

• What thermal operating limits apply to this probe?

  The hardware operates reliably across a temperature range from -51 deg C up to +177 deg C.

• What is the purpose of the connector protector?

  It seals the ClickLoc connection to prevent moisture and fluid ingress from degrading signal quality.
