The Bently Nevada 3300 XL 50mm Proximity Probe is designed to survive the harshest steam turbine DE environments. It can continually operate and maintain its accuracy in high temperatures up to 392°F (200°C), and can withstand intermittent high temperatures up to 482°F (250°C). The 50mm probe has both a front and rear seal which, combined with the High Temperature FluidLoc cable (standard on all 50mm probes), prevent moisture from entering the probe tip. Special high-temperature ClickLoc connectors are also standard on the probe and extension cable. Each probe and cable comes with connector protectors and a disposable connector protector installation tool to ensure that the connectors remain free of contamination. The ClickLoc connector on the probe lead features a removable collar that facilitates routing the cable through tight clearances.
The 3300 XL 50mm probe is available in straight exit case styles with 1/2 - 20 English threads or M14x1.5 metric threads, including a locknut with predrilled safety wire holes. The side exit probe has two 1/4 - 20 mounting holes in the rear of the probe case. For both straight exit and side exit probes the overall case diameter is 1.99 inches.
