2EN Sensors

2EN, after several years of research, development and experimental operation began production of anemometers and wind vanes.

Innovation

Both sensors - anemometer/wind vane - operate on the same principle which is based on angular displacement of their moving parts.
By changing each sensor's top-moving part and firmware, the sensor operates either as an anemometer or as a wind vane.

Principle of operation

A moving magnet is attached on the rotating axle of the sensor. The absolute angle measurement provides instant indication of the magnet's angular position with a resolution of 256 positions per revolution. This digital data is handled by the sensors' firmware and is translated either in wind speed or angular position. A user programmable incremental output is available as a serial bit stream or as a PWM singal allowing implementation of SDI or analogue interface.

Sensor Design Parameters

  • Clever on chip firmware (MCU)
  • Aerodynamic shape
  • Robust behavior
  • Linear response
  • Low starting offset
  • Implement indicator for maintenance

Certifications

The sensor has been tested for electromagnetic stability.
According to EMC HELLAS S.A., 2EN sensors conform to the requirements of EU Harmonized Standards: EN 61326-1.
