Installation & Setup Guidance
Proper installation of the Bently Nevada 330301-000-011-20-90-00-00 ensures accurate readings. Mount the probe using the 3/4-16 UNF threads into a pre-tapped hole. Ensure the target surface is flat and meets the minimum diameter of 30.5 mm. The extension cable (9.0 metres) connects directly to the probe; do not exceed 305 metres of field wiring to maintain frequency response. For best results, use the supplied hardline cable (2.0 metres) without armor (option 00).
Maintenance & Reliability
In high-temperature applications, the Bently Nevada 330301-000-011-20-90-00-00 reduces downtime through robust construction. The ceramic tip withstands thermal cycling, while the stainless steel case resists oxidation. Regular inspection of cable connections for wear is recommended. The probe maintains ISF within ±30% of nominal over the full temperature range, minimizing drift. This reliability supports continuous monitoring without frequent recalibration.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330301-000-011-20-90-00-00, verify that your system requires a 3/4-16 UNF threaded probe with a 9-metre extension cable. This model is not approved for hazardous areas (Agency Approval Option: 00). For applications needing stainless steel armor, choose option 10.
