Description Transducer System The 3300 XL 11 mm Proximity Transducer System consists of: • 3300 XL 11 mm probe • 3300 XL 11 mm extension cable • 3300 XL 11 mm Proximitor® Sensor1 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 our 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. Contact your local sales and service representative for assistance
