CS650 and CS655 Water Content
Reflectometers
1. Introduction
The CS650 and CS655 are multiparameter smart sensors that use innovative
techniques to monitor soil volumetric water content, bulk electrical
conductivity, and temperature. They output an SDI-12 signal that many
Campbell Scientific dataloggers can measure.
The CS650 has 30 cm length rods, whereas the CS655 has 12 cm length rods.
This manual uses CS650 to reference model numbers CS650 and CS655.
Unless specifically stated otherwise, information in the manual applies equally
to both models.
This manual provides information only for CRBasic dataloggers.

2. Precautions
•
section at the front of this
manual.
•
Although the CS650 is rugged, it should be handled as precision scientific
instrument.
•
External radio frequency (RF) sources can affect the sensor operation.
Therefore, the sensor should be located away from significant sources of
RF such as ac power lines and motors.
3. Initial Inspection
•
Upon receipt of the CS650, inspect the packaging and contents for
damage. File damage claims with the shipping company.
•
The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the expected product and cable length were received.
