7 Replacement Hygroscopic Discs
For Rain Bird Wired Rain Sensors (Model RSDBEX & RSD)
Rain Bird No Bracket Rain Sensors (RSDCEX)
And
Rain Bird Wireless Sensors (All WR2 models)
Brand
New replacement hygroscopic discs for Rain Bird Rain Sensors. If your
Rain Bird Rain Sensor is not working well, the likely cause is that your discs
have weathered over time and are not functioning properly anymore.
Instead of throwing away the entire sensor, just remove the spindle and
cap and replace the worn out discs with these 7 new ones.
The
way this rain sensor works is that when rain hits these discs, they expand and
push a switch off that is connected to the controller. When it stops
raining and the discs dry out, they contract back to the original size and
release the switch. If these discs get excessively dirty, are more than
4 years old, or have bugs living in and around them, they might not function
properly. This is a simple tool free fix that should take no more than 5
minutes.
This
auction contains enough discs to repair one Rain Bird rain sensor.
These
discs are from a different manufacturer from the original discs that Rain Bird
used. There should be 6 discs on your sensor that you need to replace.
These discs are thinner than the original Rain Bird discs and that is
why you need 7 to replace them and have the sensor function properly.
The inner diameter and outer diameter of the discs are identical. I have
done testing of the thickness of these discs before wetting, after wetting, and
after drying out to make sure that the sensor will perform the same as it did
when it was brand new. These replacement discs are high quality OEM
hygroscopic discs from another manufacturer of irrigation rain sensors.
