Industry Applications
The Bently Nevada 330195-02-12-10-CN excels in monitoring shaft vibration and position in turbines, compressors, and pumps. Its reverse mount design allows installation in tight spaces where standard probes cannot fit. The humidity resilience (less than 3% change in ASF at 93% RH) makes it suitable for harsh environments such as offshore platforms and chemical plants. For extended temperature applications, the probe tip withstands up to +218°C, ensuring reliable operation in high-heat zones.
Installation & Setup Guidance
When installing the Bently Nevada 330195-02-12-10-CN, ensure thread engagement does not exceed 0.563 inches to avoid mechanical damage. The probe uses a Viton O-ring for pressure sealing. Note that probes are not pressure tested prior to shipment. For applications requiring a pressure test, contact our custom design department. Align the probe perpendicular to the target surface to maximize accuracy.
Maintenance & Reliability
Operate the probe within the standard temperature range of -52°C to +177°C. For extended temperature probes, the tip can handle up to +218°C, while the cable and connector endure up to +260°C. Avoid exposing the probe to temperatures below -34°C to prevent premature pressure seal failure. The PPS tip and stainless steel case resist corrosion and wear, reducing maintenance intervals. The probe's robust design minimizes the risk of common failure modes like seal leaks and signal drift.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330195-02-12-10-CN, verify the total length option (10 = 1.0 meter) and agency approval (CN country specific). For custom pressure testing requirements, reach out to our team at PLC Source PRO, your trusted supplier for Bently Nevada industrial automation parts.
