A wind speed and direction indicator to display digital data and output alerts. * Sensor W639-ED1 (Cat. No. 7910-00) must be purchased together.
■ This digital indicator is designed to be used with Wind Speed and Direction Sensor W639-ED1 (Cat. No. 7910-00).
It receives the signals from the sensor and displays instantaneous and mean values of wind speed in digital and one of 16 points of compass for wind direction on an LED panel. Alarms can be set at your will and is output as a relay contact, hazard lamp, and a buzzer. Furthermore, analog and digital output to external devices by RS-422 communication is available on inquiry.
■ The sensor adopts a brushless potentiometer for wind direction and an optical pulse sensor for wind speed to realize high reliability.
■ Wind direction is indicated as a lamp of one of 16 cardinal directions, and wind speed (instantaneous and mean) is indicated as digital figures.
■ 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 |
| Available range of wind direction alarm | Specify two angles from 0 to 359° either instantaneous or mean direction |
| 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 |
| Content of wind direction alarm | Dry contact (contact capacity 24VDC, 1A), blinking of LED of the appropriate cardinal direction
* Wind direction alarm is output from the third alarm terminal so it cannot be set with third wind speed alarm together. |
■ Analog output option available on inquiry
Number of channels: 2 channels
Output content:
Ch1: instantaneous or mean wind speed 0–1VDC for 0–(10–90*)m/s
Ch2: instantaneous or mean wind direction 0–1VDC for 0–360 (or 540*)°
* Content and ranges can be specified to order
* Output impedance less than 500Ω
■ Digital output option available on inquiry
Number of channels: 1 channel
Protocol: RS-422
Output content: instantaneous wind speed/direction, mean wind speed/direction, max./min. instantaneous wind speed, max./min. mean wind speed, operation status, monitored status of power source
Transmission interval: 0.25, 0.5, 1, 5, or 10 seconds
