3. REED ANEMOMETERS OR RAIN GAUGES.
Switch-type sensors (reed):
Anemometers: VECTOR A100R, NRG #40H.
Rain Gauges: NRG RainGage, YOUNG Tipping Bucket
CONNECTION:
Connect the first anemometer or rain gauge to screws 1 [CH1] and 2
[GND] on the left screw terminal.
Connect the second anemometer or rain gauge to screws 6 [CH8] and 5
[GND] on the right screw terminal. If you are using a datalogger with
Serial Number starting with ‘026A’, connect a 20kΩ pull-up resistor for
CH8, between [CH8] and external power supply 12 V [+BAT Ext].
Wire polarity does matter only for NRG’s #40H anemometer. In the
connection figure below, the signal pin (CH1/CH8) is the white one, the
[GND] pin is the black one, while connect the red one as well to the 12V
power supply [+BAT Ext].
Typical wire size: 2 x 0,25 mm
2
(shielded cables are recommended).
Connect the shield to the GROUND screw and the metal body of the
anemometer (if plastic, leave it unconnected).
IN CASE IT DOESN’T WORK:
Check that the anemometer or rain gauge rotates freely and that its axle
is straight.
With a multimeter check the resistance in the sensor’s terminals: it
should change from short circuit to open circuit while moving or rotating.
