Digital Indicator with Alarm

Feature

■ This digital indicator is designed to be used with Wind Speed Sensor W11 (Cat. No. 7915-00).

It receives the signals from the 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.

■ The 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.

Available range of wind speed alarm	5 to 90 m/s either instantaneous or mean speed
Content of first wind speed alarm	Dry contact (contact capacity 24VDC, 1A), slow blinking of green LED, slow intermittent buzzer
Content of second wind speed alarm	Dry contact (contact capacity 24VDC, 1A), quick blinking of yellow LED, quick intermittent buzzer
Content of third wind speed alarm	Dry contact (contact capacity 24VDC, 1A), lighting of red LED, continuous buzzer
