Overview

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

• 3300 XL 8 mm Probe
• 3300 XL Extension Cable
• 3300 XL Proximitor Sensor

This system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. It can measure both static (position) and dynamic (vibration) values. Primary applications include:

• 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:

  • Requires -17.5 Vdc to -26 Vdc when installed with non-incendive circuit connected (per installation drawing 140979), with a maximum current consumption of 12 mA.
  • Requires -23 Vdc to -26 Vdc with barriers.
  • Operation at voltages more positive 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

• Material: A308 Aluminum

• Weight: 246 g (8.67 oz)

• Operating Temperature: -52°C to +100°C (-62°F to +212°F)

• Storage Temperature: -52°C to +105°C (-62°F to +221°F)
