BENTLY NEVADA 330100-50-00 3300 Proximitor Sensor

Product Overview

The Bently Nevada 330100-50-00 is a 3300 Proximitor Sensor designed for non-contact displacement measurement in rotating machinery monitoring systems. It conditions signals from compatible proximity probes and extension cables, providing an output voltage proportional to the distance between the probe tip and a conductive target. It supports shaft vibration, position, and rotational speed monitoring applications.

Applications

• Steam and gas turbine monitoring

• Industrial compressor protection

• Pump and motor shaft monitoring

• Bearing vibration measurement

• Shaft displacement and position monitoring

• Rotational speed monitoring

• Machinery condition monitoring and predictive maintenance

Important Notes

• This model is a Proximitor Sensor, not a proximity probe.

• A compatible probe and extension cable are required to form a complete transducer system.

• The sensor requires a negative DC supply; do not connect it directly to a standard positive 24 V DC supply.

• The 5.0 m option refers to the complete transducer system length, not the standalone sensor's physical dimensions.

• Model 330100-50-00 is a legacy product; 330180-50-00 is listed as its replacement. Verify compatibility before substituting.

• Confirm the complete part number, system length, mounting arrangement, and product condition before ordering.
