ET107 Weather Station
2.4.10 CS650-LC or CS655-LC Soil Water Content Sensor Plus (Optional)
The CS650-LC and CS655-LC are multiparameter smart sensors that use
innovative techniques to monitor soil volumetric water content, bulk electrical
conductivity, and temperature. These sensors do NOT have an armored outer
jacket. The jacket is waterproof but NOT cut proof. The recommended
method is to bury conduit from the weather station to the soil water content
measurement site and route the sensor cable through the conduit. Bury the end
of the sensor so its rod ends are in contact with the soil surface to be measured.
See CS650 and CS655 Water Content Reflectometer manual for complete
instructions.
The CS650-LC or CS655-LC plugs into the enclosure connector marked
“SDI-12”.
The cable used with the CS650-LC and CS655-LC is waterproof
but not armored. Route cable through conduit if rocky soils or
rodents are present.
2.4.11 Sensor Connections
Sensor schematics are provided in Section 4.3.1, Sensor Schematics.
1. Each sensor cable plug attaches to a unique bulkhead connector as shown
in FIGURE 2-24. The sensor cables are individually marked to match up
with the sensor labeling on the back of the enclosure.
The 034B Wind Sensor plugs into the connector labeled
WS/WD. Plugging this sensor in the connector labeled
SDI-12 may damage the sensor and/or the main
enclosure connector board.
