4.1.4 Sensor Maintenance
Sensor maintenance should be performed at regular intervals, depending on the
desired accuracy and the conditions of use. A suggested maintenance schedule is
outlined below. See Appendix A for an example of a maintenance log file. Log
file is for one year of station use.
1 week
•
Check the rain gage screen and funnel for debris and level.
1 month
•
Check the solar radiation sensor (pyranometer) for level and
contamination. Gently clean with blast of dry air, soft camel hair brush, or
clean water if needed.
Handle the pyranometer carefully when cleaning. Be
careful not to scratch the surface of the sensor.
CAUTION
•
Do a visual/audio inspection of the 034B-ET’s anemometer at low wind
speeds. Worn bearings can cause the wind cups to spin in an uneven
manner and/or make a grinding sound.
•
Check the WindSonic1-ET for contamination. If needed, gently clean the
WindSonic1 with a cloth and mild detergent.
When cleaning the WindSonic1, do not use solvents and
avoid scratching the sensor.
CAUTION
3 months
•
Clean the Gill Radiation Shield by removing the two Phillips screws
holding it to the sensor arm. Gently pull the sensor out of the shield. Clean
the gill shield using warm mildly soapy water. Rinse with clean water and
allow the shield to dry before putting it back on the sensor arm.
•
If necessary clean the white filter element on the end of the temp/RH
sensor. To clean the filter, unscrew it from off the end of the sensor and
put it in a cup of CLEAN DISTILLED WATER. Use no soap. Agitate the
filter in the cup of water. Remove the filter and allow to air dry before
putting it back on the end of the sensor.
