Overview

• The 3300 NSv probe and extension cable are mechanically and electrically compatible with Bently Nevada’s previous 3300 RAM proximity probe and extension cable.
• The NSv probe offers increased chemical resistance compared to the 3300 RAM probe, making it suitable for use in many process compressor applications.
• The side-view characteristics of the 3300 NSv probe are superior to those of the 3000-series 190 probe when gapping the 3300 NSv probe at the same distance from the probe target.

Specifications

Electrical

• Proximitor Sensor Input

  • Accepts one noncontacting 3300 RAM or 3300 NSv Proximity Probe and Extension Cable.

• Power Requirements

  • Requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption.
  • Requires -23 Vdc to -26 Vdc with barriers.
  • Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range.
