Product details
1.Technical principles and architecture
Core working mechanism
Signal processing:
Receive digital pulses or analog signals through the sensor,calculate the speed/rudder angle value through the CPU count port,and drive the stepper motor to accurately locate the pointer(1/3°per step)
Display technology:
Five-digit dynamic LCD floating point display,supports multi-unit switching of speed(0.1~3000m/min linear speed),frequency(0.0167~1666.6Hz)
Rudder angle indication optimization
Alternative traditional flaws:
Solve the error of the indicator value caused by moisture corrosion and voltage fluctuations in inductive rudder angle meter,and adopt the sliding contact voltage divider design to improve stability
