SK SATO 7910-00 - Model W693-ED1 Wind Speed and Direction Sensor for Digital Indicator with Alarm

Description

This model is an airplane type wind speed and direction sensor that can transmit the measured data to the indicator to display wind speed in digital and wind direction with LED, and also output alarm.
The digital indicator with alarm is purchased separately.

No. 7910-00 is a wind speed and wind direction sensor using by connecting with No. 7910-50 indicator with alarm.   The indicator inputs the signals that are output from this sensor and displays instantaneous and mean values of wind speed in digital and 16 azimuth for wind direction with LEDs.

The alarm value that is output from the indicator can be arbitrarily set and are transmitted to a warning lump and buzzer.  Furthermore, it is available to add analog output and digital output (RS-422) at option as a external output.


Features

Brushless potentionmeter for wind direction and optical pulse for wind speed are adopted.Wind direction is indicated with LED (16 azimuth) and wind speed (instantaneous and mean) is indicated with digital figures..Three alarm outputs (alarm 1, 2 adn 3)  are provided.   When the values reach the thresholds, it operates alarm with relay contact, warning lump and buzzer sound.

Instantaneous or mean,  alarm setting range: 5 to 90m/s (Mutual setting in alarm 1, alarm 2 and alarm 3)

Alarm output (wind direction)

. No voltage make contact , Contact capacity: 24VDC, 1A (resistance load) * the signal of the alarm contact is output from alarm 3
.LEDs of 16 azimuth: LED blinks to indicate the alarm setting section

(Wind speed- alarm 1)

. No voltage make contact:  contact capacity:24VCD, 1A (resistance load)
. Green LED (slow blinks)
. Buzzer (long intermittent sound)

(Wind speed-alarm 2)

. No voltage make contact   Contact capacity: 24VDC 1A (resistance load)
. Yellow LED blinks (fast blinks)
. Buzzer sound (short intermittent sound)

(Wind speed-alarm 3)

. No voltage make contact  Contact capacity 24VDC, 1A (resistance load)
. Red LED blinks (continuous blinks)
. Buzzer sound (continuous sound)
* If the alarm sound in wind direction is set, the alarm 3 is not usable for wind speed

Alarm reset

. When contact output and wind speed value of LED display are smaller than the value of the alarm setting / the value of wind direction is out of the range to be set.
. Buzzer sound (continuous sound): by the key operation of the front panel
