Product Overview
Signal Processing
Input: 3300 NSv proximity probe + extension cable (5m/7m optional).
Output: 4–20 mA axial displacement (thrust) signal, proportional to shaft position.
Accuracy: ±1.5% (typical), test input into a 250Ω load.
Diagnostic Interface
Non-isolated "PROX OUT" terminals provide dynamic vibration/gap voltage signals. Requires an isolation adapter (122115-01) to connect to AC-powered devices.
Not OK/Signal Defeat: Output <3.6 mA (response time ≤100 μs) in case of a fault.
Calibration and Adjustment
Independent zero and span potentiometers.
Test Input Pin: Supports a DC voltage source for quick verification of the output signal.
Environmental Compatibility
Operating Temperature: -35°C to +85°C.
Ingress Protection: 100% condensing humidity (non-submersible). Structure: potting design, anti-vibration/corrosion.
Feature
High-Precision Measurement: Bently Nevada 991-01-XX-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 991-01-XX-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 991-01-XX-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 991-01-XX-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 991-01-XX-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.
Notes
Probe Calibration
The gap setting must be accurate, otherwise the full range will not be achieved.
Signal Isolation
When using "PROX OUT," isolation must be performed using the 122115-01 adapter to prevent ground loop interference.
System Limitations
Advanced features of continuous monitoring systems (such as Danger Bypass and Trip Multiply) are not supported.
PLC connections are not suitable for plant-wide diagnostics (such as System 1).
Threaded Mounting
Excessive engagement may damage the probe.
