Applications
The 146054-08-05-01-05 is ideal for monitoring shaft vibration, radial position, and thrust position in turbines, compressors, pumps, and other rotating equipment. Its ceramic tip offers excellent wear resistance, and the stainless steel case ensures durability in corrosive environments. The ATEX and IECEx approvals make it suitable for hazardous areas where explosive atmospheres may be present.
Installation & Setup
When installing the 146054-08-05-01-05, ensure the target surface is clean and free of debris. Mount the probe with the specified thread engagement (maximum 0.563 in) and verify the gap according to the system calibration. Use the recommended torque to avoid damaging the ceramic tip. Always follow the manufacturer's guidelines for cable routing to prevent signal interference.
Maintenance & Reliability
This probe requires minimal maintenance. Periodically inspect the cable and connector for wear or damage. Keep the probe tip clean and avoid impact. The operating temperature range of -51°C to +177°C ensures reliable performance in extreme conditions. The pressure rating of 34 Bar (500 psi) nitrogen makes it suitable for high-pressure applications.
