Wired Anemometer 0-10V Output PLC Package

Regular price $258.00

Anemometer 0-10V Output PLC Package

This item converts an anemometer AC frequency input into a 0-10VDC output for use in a PLC control system.

This combination package of the ET-40AC wired anemometer (p/n 003016) with the ET-F2V Converter Assembly (p/n 003007) is an ideal solution for wind speed fountain control applications where linear wind measurements are used for VFD pump control.

Specifications

  • Conical cups measure 51 mm (2 inches) in diameter
  • Rotor diameter is 190 mm (7.5 inches)
