Feature
High-Precision Measurement: Bently Nevada 991-25-50-01-00 with a sensitivity of 7.87mV/μm, it accurately captures minute shaft vibrations and displacement changes, providing reliable data for evaluating equipment operating conditions.
Easy Installation and Maintenance: Bently Nevada 991-25-50-01-00 with the integrated design reduces external components, enabling versatile and convenient installation and facilitating routine maintenance and inspection.
Stable Signal Output: Bently Nevada 991-25-50-01-00 with fault detection circuits, such as "not ok" and "signal failure," prevent high output or false alarms caused by probe failure or loose connections.
Application
Energy and Power: Bently Nevada 991-25-50-01-00 used in steam turbines, generators, and other equipment to monitor shaft thrust changes in real time and prevent equipment damage caused by abnormal thrust.
Petrochemical: Bently Nevada 991-25-50-01-00 installed on key equipment such as compressors and pumps, it monitors shaft operating conditions and promptly detects problems such as seal failure and bearing wear caused by thrust imbalance.
Probe Requirements
Must be used with the 3300 NSv series probe (such as the 330902, 330904, etc.). Key Parameters:
Probe Gap: Adjust strictly according to the manual. Incorrect settings will result in signal loss.
Connector: Coaxial connector (diameter ≤ 7.23mm).
Application Limitations
Non-continuous Monitoring: Only provides thrust position alarm and signal defense functions. Advanced monitoring functions such as hazardous bypass and trip multiplication are not supported.
Diagnostic Isolation: The PROX OUT signal must be isolated via a test adapter to prevent ground interference.
PLC Compatibility: Not suitable for plant-wide diagnostic systems.
