Description：

The 3300 XL 11 mm Proximity Transducer System has a 3.94V/mm (100 mv/mil) output for non-contacting vibration anddisplacement measurements on fluid film bearing machines.The large 11 mm tip enables this transducer system to have alonger 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 steamturbines

Rod position or rod drop measurements onreciprocating compressors

Tachometer and zero speed measurements

Phase reference (Keyphasor) signals

Product Applications

Power Industry: Monitoring the internal vibration and axial displacement of bearing housings in steam turbines, gas turbines, generators, and large feedwater pumps in thermal power plants and nuclear power plants to prevent unit damage due to severe vibration.

Oil and Gas: Used in large centrifugal compressors, reciprocating compressors, and crude oil pumps on offshore drilling platforms, oil refineries, and long-distance pipelines.

Large-Scale Chemical and Petrochemical Industries: Protecting various process gas compressors and turbine drives in ethylene and ammonia synthesis plants to ensure continuous and safe production under high-temperature and high-pressure environments.

Heavy Industry and Metallurgy: Monitoring the mechanical condition of large blast furnace blowers, sintering blowers, high-power gearboxes in steel plants, and central main fans in coal mines.

Water Treatment and General Manufacturing: Used for mechanical condition monitoring of large vertical/horizontal pumps and mixers in large urban water pumping stations or industrial circulating water systems.
