Installation and Setup Guidance
Proper installation of the Bently Nevada 330302-000-011-10-90-00-00 3300 High Temperature Probe ensures accurate monitoring. Mount the probe with the specified unthreaded length of 0mm and overall case length of 11mm. Secure the hardline cable (1.0m) and extension cable (9.0m total) without sharp bends. For optimal performance, target a flat surface at least 30.5mm in diameter. Avoid excessive torque during mounting to prevent damage to the ceramic tip. The probe does not require stainless steel armor for the extension cable, as indicated by the '00' option.
Maintenance and Reliability
The 330302-000-011-10-90-00-00 is engineered for long-term reliability in harsh environments. Its ceramic tip resists wear, and the AISI 316L stainless steel case provides corrosion resistance. The probe's ISF remains stable within ±30% over the full temperature range from -34°C to +350°C, minimizing signal drift. Routine checks should include verifying the extension cable connection and inspecting for physical damage. Frequency response remains consistent up to 6 kHz with typical field wiring lengths of 305 metres. This reliability reduces unplanned downtime and lowers total cost of ownership.
Selection Guide
When selecting the Bently Nevada 330302-000-011-10-90-00-00 3300 High Temperature Probe, verify that your system requires a hardline length of 1.0m and a total length of 9.0m. The probe is designed for high-temperature applications up to +350°C. Ensure the target shaft diameter is at least 152mm.
