Overview

The 3300 XL 8 mm Proximity Transducer System includes the following components:

• One 3300 XL 8 mm probe
• One 3300 XL extension cable
• One 3300 XL Proximitor Sensor

The system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It can measure both:

• Static (position) values
• Dynamic (vibration) values

Primary applications:

• Vibration and position measurements on fluid-film bearing machines
• Keyphasor reference and speed measurements

Specifications

Proximitor Sensor

• Input: Accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable.
• Power Requirements:
  • Requires -17.5 Vdc to -26 Vdc when installed with non-incendive circuit (as per installation drawing 140979) with a maximum consumption of 12 mA.
  • Requires -23 Vdc to -26 Vdc when using barriers.
  • Operation at a more positive voltage than -23.5 Vdc may result in reduced linear range.
• Supply Sensitivity:
  • Less than 2 mV change in output voltage per volt change in input voltage.
• Output Resistance: 50 Ω

System

• Length: 5 or 9 meters (including extension cable), or 1 meter (probe only).
• Materials: A308 aluminum.
• Weight: 246 g (8.67 oz).
