Frequently Asked Questions (FAQ)

• Can I use this probe with my existing 3300 RAM extension cable?
  Yes, the 3300 NSv Proximity Probe is mechanically and electrically interchangeable with previous 3300 RAM probes and cables.
• What is the incremental scale factor for this probe?
  It provides 7.87 V/mm (200 mV/mil) over the full 1.5 mm linear range, including interchangeability error.
• What is the maximum temperature this probe can withstand?
  The probe operates continuously from -52°C to +177°C (-62°F to +351°F).
• Does this part include the extension cable?
  No, this order includes only the probe with integral cable (0.5 m). You can order extension cables separately.
• How do I install the probe correctly?
  Finger-tighten the probe tip, then follow the recommended torque of 7.5 N•m for the case threads. Avoid exceeding 0.56 N•m on the tip itself.
• What field wiring length does the system support?
  You can use up to 305 meters (1000 feet) of triad cable between the proximitor and monitor without significant signal loss.
