Description –

The Pulse Rate Detector accepts pulses from an Anemometer and when the Wind Speed reaches an adjustable Wind Speed set point the Pulse Rate Detector will close a contact which in turn will temporarily interrupt the Sprinkler. The Pulse Rate Detector automatically distinguishes between periodic Wind Gusts and sustained High Wind Speeds which minimizes unnecessary interruption of the Sprinkler.
