Bently Nevada 330100-50-00 3300 Proximitor Sensor

Description

The Bently Nevada 330100-50-00 3300 Proximitor® Sensor offers many improvements over previous Bently Nevada eddy current transducers with better linearity and temperature stability. It also uses an integral isolation plate as its base, eliminating the need for separate isolator plates.

Specifications

Unless otherwise noted, the following specifications are for a proximity transducer system between 18°C and 27°C (64°F to 80°F) with a -24 Vdc power supply, a 10 k Ω load, an AISI 4140 steel target, and a probe gapped at 1.27 mm (50 mils).

Electrical

Proximitor® Sensor

• Input: Accepts one noncontacting 3300 5 mm, 3300 8 mm, or 3300 XL 8 mm Proximity Probe and Extension Cable
• Power: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Operation at a more positive voltage than -23.5 Vdc can 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
