  INTERFACE 40C TO LOGIC LEVEL, SPEED AMP #892E (#2041)
Description  
Sensor type
  • anemometer interface, signal amplifier
  • converts the low level AC sine-wave signal from the sensor to a high level square wave signal at the same frequency.
Applications
  • wind turbine control
  • process control
  • environmental monitoring
  • meteorological studies
Sensor compatibility
  • NRG #40 Anemometer
  • IceFree Heated Anemometer
Input signal  
Signal type (sensor output) low level AC sine wave
Signal range (sensor output) 0 Hz to 200 Hz
Output signal  
Signal type
  • high level square wave
