The Bently Nevada 3300 XL 25mm Proximity Probe comes in a large variety of case configurations to physically replace all standard 7200 25mm, 7200 35mm and 25mm DE Integral transducer systems (including side and rear exit probes). The Proximitor Sensor also has an output that is identical to that of the 7200 and 25mm DE Integral systems, allowing customers to upgrade without requiring any changes in the monitor configuration. When upgrading from previous systems, every transducer system component (probe, extension cable, and Proximitor Sensor) must be replaced with 3300 XL 25mm components.
