Its primary value lies in its \"external access\" architecture, which allows technicians to adjust the probe gap or replace the sensor without de-pressurizing the machine or initiating a full shutdown. By protecting internal sensors from high-velocity oil splash and mechanical impact, this housing significantly extends the mean time between failures (MTBF) for Turbine Supervisory Instrumentation

One of the core advantages of the 31000 series is that the probe can be moved axially within the housing. This allows for precise \"Gap\" voltage setting (-10.0 VDC for most 3300 XL systems) while the machinery is operating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the 049 penetration depth be modified?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 049 suffix indicates the factory-calculated length.

The probe should be adjusted until the voltage reads -10.0 VDC (the midpoint of the linear range). Ensure the shaft is at its normal operating position before locking the probe in place to prevent \"bottoming out\" during thermal expansion.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConduit Sealing and SST Reducer\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Option 03 fitting kit includes a 3\/4-14 NPT to 1\/2-14 NPT Stainless Steel (SST) reducer. This is critical for adapting to standard 1\/2-inch flexible conduits. Ensure that the cable seal grip and appropriate grommet (sized 1\/8 to 3\/8 inch) are utilized to prevent environmental ingress into the housing, which could lead to corrosion of the ClickLoc connector.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThermal Expansion and Standoff Use\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 1.5-inch standoff adapter (Option 15) serves as a thermal buffer.
