Condition Monitoring and Protection
3300 Series sensors are the predecessors of 3300 XL series and are tested devices when it comes to machinery applications. It comes in two categories: the 3300 5 mm Proximity Transducer System and the other one is the 3300 16 mm High Temperature Proximity Transducer System. Aside from the difference in datasheet, the former provides an accurate and good stability of signal output of 200 mV/mil. While the latter is primarily designed to defy high temperature environments that could be as high as 350° C (662° F).
