Industry Applications
The Bently Nevada 330301-000-011-10-90-00-05 excels in high-temperature environments where standard probes fail. Common applications include:
-
Gas Turbines: Monitors shaft vibration in combustion zones where temperatures exceed 200°C.
-
Steam Turbines: Tracks bearing vibration in high-pressure stages without sensor drift.
-
Compressors: Provides reliable data in hot, corrosive atmospheres.
Troubleshooting and Reliability
High-temperature probes often face failures due to thermal expansion or insulation breakdown. The 330301-000-011-10-90-00-05 mitigates these issues with its ceramic tip and stainless steel construction. Its performance over extended temperatures maintains ISF within ±30% and DSL within ±0.51 mm (±20 mils) up to +350°C. For accurate readings, ensure the target surface meets the recommended minimum size of 30.5 mm diameter. Regularly check the probe resistance and verify extension cable integrity to prevent signal degradation.
Selection and Purchasing Guide
Before purchasing the Bently Nevada 330301-000-011-10-90-00-05, verify your mounting thread (3/4-16 UNF) and shaft diameter (minimum 152 mm). The unit comes with a 9.0 m (30 ft) extension cable without armor (option 00). For reliability, source this part from an authorized supplier like PLC Source PRO. We stock genuine modules with multiple approvals to ensure seamless integration into your control system.
