The 3300 XL 11 mm Proximity Transducer System has a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The large 11 mm tip enables this transducer system to have a longer linear range compared to the standard 3300 XL 8 mm Transducer System. It is primarily used in the following applications where the longer linear range is necessary:

Axial (thrust) position measurements

Ramp differential expansion measurements on steam turbines

Rod position or rod drop measurements on reciprocating compressors

Tachometer and zero speed measurements

Phase reference (Keyphasor) signals

The 3300 XL 11 mm Proximitor Sensor is designed to replace the 7200-series 11 mm and 14 mm Transducer Systems. When upgrading from the 7200-series system to the 3300 XL 11 mm system, every component must be replaced with 3300 XL 11 mm components. In addition, the monitoring system must be updated. If using a 3500 Monitoring System, an updated version of the configuration software that lists the 3300 XL 11 mm Transducer System as a compatible option is required. Existing 3300 Monitoring Systems may need a modification.

Frequently Asked Questions

Q1: What is the Bently Nevada 330706-005-046-10-02-CN?
