Industry Applications
The Bently Nevada 330301-000-011-20-90-01-00 excels in high-temperature turbine monitoring where conventional probes fail. Its ceramic tip and stainless steel case withstand extreme heat, while the 9.0-meter total length (including extension cable with armor) provides flexibility for remote monitoring. Typical uses include steam turbine thrust bearing monitoring, gas compressor shaft vibration measurement, and high-speed rotating equipment protection.
Installation & Setup Guidance
Mount the probe using the 3/4-16 UNF threads with proper torque to avoid damage. The unthreaded length is 0 inches, and the case length is 1.1 inches. Use the included stainless steel armored extension cable to route signals safely in harsh environments. Ensure the target surface is clean and meets the recommended minimum diameter of 30.5 mm for flat targets or 152 mm for shafts. Calibrate the system to account for the 2.0-meter hardline cable resistance of 5.82 ohms.
Maintenance & Reliability
The Bently Nevada 330301-000-011-20-90-01-00 requires minimal maintenance due to its robust ceramic tip and 316L stainless steel construction. For extended life, inspect the cable armor regularly for abrasion in high-vibration areas. The probe's frequency response remains stable up to 6 kHz with up to 305 meters of field wiring. At temperatures exceeding 22°C, the ISF stays within ±30% of 3.94 V/mm, and DSL within ±0.51 mm, ensuring reliable data over the equipment's lifetime.
Troubleshooting & Common Issues
Common failures in high-temperature probes include signal drift due to cable degradation or thermal expansion. The Bently Nevada 330301-000-011-20-90-01-00 mitigates this with a specifically designed hardline cable and armored extension. If readings become erratic, verify the probe resistance (5.82 ohms) and inspect the tip for contaminant build-up. For systems with longer cable runs, ensure the total wiring length does not exceed 305 meters to maintain specified frequency response. PLC Source PRO recommends checking the extension cable armor integrity annually.
Selection Guide & Purchasing Advice
Before purchasing, confirm that your application requires a high-temperature probe (up to 350°C) and that the thread size matches your mounting hole (3/4-16 UNF). The Bently Nevada 330301-000-011-20-90-01-00 includes the extension cable with stainless steel armor, so no additional cable is needed.
