• Field Wiring: Use 0.2 to 1.5 mm² (16 to 24 AWG) or 0.25 to 0.75 mm² with ferrules. We recommend a three-conductor shielded triad cable.
• Maximum Field Wiring Length: 305 meters (1000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. Refer to frequency response graphs for signal rolloff at high frequencies.

Frequently Asked Questions (FAQ)

• Q: Is this 3300 NSv probe fully compatible with older 3300 RAM systems?
  A: Yes, the 330903-00-05-10-01-05 is mechanically and electrically interchangeable with previous 3300 RAM probes and extension cables.
• Q: What is the recommended gap voltage at the 1.0 mm setting?
  A: At 1.0 mm (40 mils) gap, the output voltage typically falls between -1 and -13 Vdc, with linear behavior across the 1.5 mm range.
• Q: Can I use this probe for high-pressure compressor applications?
  A: Yes, the NSv model offers increased chemical resistance and a Viton O-ring seal. However, we do not pressure test probes before shipping. Contact our custom design department if you require a pressure seal test.
• Q: What happens if the target diameter is smaller than 13 mm?
  A: A smaller shaft diameter may alter the scale factor. You can reduce the gap between the probe and target to minimize this effect.
• Q: How long is the total probe cable and what type?
  A: This version comes with a 1.0 meter (39 inch) 75 Ω coaxial FEP insulated cable with a ClickLoc connector.
• Q: Do you have stock and how fast do you ship?
  A: Yes, we have the 330903-00-05-10-01-05 in stock. We ship within 5 days using FedEx, UPS, or DHL.
