a)
Sensors on the LINK900 system
Sensors can play a very important role when using a Golf Central Control. Here are some
examples of sensors and reasons to use them:
1)
Flow Sensors: Allows the user to monitor flow at a pump station, monitor transfer
pumps, etc.
2)
Temperature Sensors: The Golf central control can be configured to react to high or
low temperature conditions, or to just monitor conditions
3)
Rain Sensors: RainWatch is one example. It is an intelligent rain monitoring system
that allows the central to react and compensate irrigation based on rainfall
4)
Etc.
Sensor Types:
Two types of sensors can be used on a LINK900 system: Static or Pulse.
Static sensors:
Their output is a switch closure (just like an on/off switch). Examples of a
static sensor:
Rain shut off device
Rain Check
WR-2 Wireless Rain / Freeze Sensor
