Technical Data

Transducer Operating Mechanics

This Narrow Side-View sensor relies on radio-frequency modulation to track relative distance changes between the probe tip face and a conductive shaft target. It maintains a standard scale factor of 7.87 V/mm (200 mV/mil). Because of its localized electromagnetic field design, it delivers accurate readings on shaft diameters under 51 mm or flat surfaces under 15 mm where standard 8 mm probes experience edge effects. Proper signal linearity is achieved by adjusting the mechanical gap until the static output registers between -9 Vdc and -11 Vdc.

Package Contents

• 1 x 330910-00-16-10-02-00 3300 NSv Proximity Probe (M10 x 1 threaded case, 160 mm length, 1.0 m integral armored cable with ClickLoc connector)

Installation Guidelines

• Thread Engagement: Thread the M10 x 1 housing into the machine mounting port, observing a recommended torque of 5.1 N m (45 in-lb) and a strict maximum ceiling of 33.9 N m (300 in-lb).
• Target Parameters: Ensure the target diameter is at least 8.9 mm, though 13 mm is preferred to preserve absolute scale factor linearity.
• Gap Voltage Tuning: Set the cold gap position using a digital voltmeter across the Proximitor monitor terminals to verify the -10 Vdc target operating center.
• Lead Routing: Anchor the armored cable away from high-voltage motor feeds to eliminate induced electrical noise on the high-frequency carrier wave.
• Connection Locking: Push the ClickLoc connector pairs together firmly until an audible snap verifies complete pin seating.

Frequently Asked Questions

• What specific machinery layout requires the NSv probe series?

  It is built for centrifugal air compressors, refrigeration units, and process gas compressors with restricted internal clearance.

• Can this probe be paired with standard 8 mm system components?

  No, NSv probes require matching NSv extension cables and NSv Proximitor sensors to maintain proper electrical calibration.

• What happens if the monitored shaft is smaller than 30 mm?

  Shafts under 30 mm (1.2 in) introduce localized target curvature that alters the nominal scale factor, requiring specific calibration checks.

• Does the probe require direct electrical grounding to the machine casing?

  The probe body is grounded through the machine mounting threads, but the coaxial shield must be managed to prevent ground loops.

• What is the pull strength rating of the cable joint?

  The proprietary CableLoc design provides 220 N (50 lb) of pull strength resistance between the cable and the probe tip.

• Is the integral cable protected against harsh chemical environments?

  Yes, the lead features an outer stainless steel armor sheath combined with chemical-resistant jacketing material.

• What is the minimum flat target diameter needed for accurate readings?

  A minimum flat target diameter of 8.9 mm (0.35 in) is required for basic signal return.

• Can this unit replace legacy 3000-series 190 systems?

  Yes, but upgrading from older 3000 or 7000 series systems requires replacing the probe, extension cable, and Proximitor sensor simultaneously.
