Feature
■ This three-cup anemometer is a sensor designed to be used with Digital Indicator with Alarm WAT6D0-3-00 (Cat. No. 7915-50).
The indicator receives the signals from this sensor and displays instantaneous and mean values of wind speed digitally. Alarms can be set at your will and is output as a relay contact, hazard lamp, and a buzzer. Furthermore, analog and RS-422 digital output to external devices are available on inquiry.
■ This lightweight, durable, and stable sensor generates voltage itself by rotation of the three-cup anemometer to output to the indicator.
■ Instantaneous and mean wind speed are indicated as digital figures on the indicator.
■ Three step of alarm can be set. When the measured value reaches the threshold all of the relay contact, hazard lamp, and buzzer are activated.
