Product Features
Bently Nevada 139554-01 supports 4-channel inputs to monitor positional changes of multiple mechanical parts simultaneously.
Bently Nevada 139554-01 can convert AC LVDT sine wave signals to linear DC voltages (e.g. ±10 V DC) to eliminate noise interference.
Bently Nevada 139554-01 can set warning/danger thresholds independently for each channel, triggering relay outputs.
Bently Nevada 139554-01 supports a 2-out-of-2 or 3-out-of-2 voting mechanism to ensure system reliability. Real-time display of module operating status through LED indicators.
Product Using Principle
The AC LVDT sensor generates an AC voltage signal proportional to displacement by electromagnetic induction.
Bently Nevada 139554-01 demodulates the signal, separating amplitude and phase information and filtering out high frequency noise.
It compensates for sensor nonlinearity with built-in algorithms and outputs a highly accurate DC signal.
The processed data is transmitted to the monitoring system via the 3500 frame's internal bus.
Product Application
Bently Nevada 139554-01 can monitor key parameters such as shaft displacement and differential expansion of turbines and compressors.
Bently Nevada 139554-01 can feedback valve opening control, actuator position.
Bently Nevada 139554-01 can monitor the dynamic position of gearboxes and motor bearings to prevent mechanical failures.
Bently Nevada 139554-01 can measure and analyze high-precision displacement in laboratory environment.
