3.1.2 Sensor Support
Read More! See Sensor Support (p. 37)
The following sensor types are supported by the CR200(X) datalogger. Refer to
Sensors (Appendix p. 29) for information on sensors available from Campbell
Scien
tific.
• Analog voltage
• Analog current (with a shunt resistor)
• Resistive bridges
• Pulse output
• Period output
• Frequency output
• SDI-12 sensors
A library of sensor manuals and application notes are available at
www.campbellsci.com to assist in measuring many sensor types. Consult with a
Campbell Scientific applications engineer for assistance in measuring unfamiliar
sensors.
3.1.3 Input / Output Interface: The Wiring Panel
The wiring panel of the CR200(X) is the interface to all CR200(X) functions.
Most CR200(X) functions are best introduced by reviewing features of the
CR200(X) wiring panel. FIGURE. CR200(X) Wiring Panel (p. 5) illustrates the
wiring
panel and some CR200(X) functions accessed through it.

information.
3.1.3.1 Measurement Inputs
Measurements require a physical connection with a sensor at an input channel
and CRBASIC programming to instruct the CR200(X) how to make, process,
and store the measurement. The CR200(X) wiring panel has the following input
channels:
Analog Voltage: 5 channels (SE 1–5).
• Input voltage range: 0 mV to 2500 mV.
• Measurement resolution: 0.6 mV
