Wiring
All SDI-12 sensors wire to GND, +12 and Data on the Xpert. Multiple wires can be connected to
the same connections.
Description
This general-purpose sensor block is used to obtain data from a SDI-12 sensor (parameters 1
through 20; to retrieve a parameter above 20, please use the Xpert Basic “SDICollect” function).
Select the SDI-12 address of the sensor, the measurement command type* and the units to report
with the reading. The C (concurrent measurement) command is only supported by SDI sensors
versions 1.3 and higher.
*NOTE: The only supported commands are V, M, MC, M1 - M9, C, CC, C1 - C9, R0-R9, RC0-
RC9. To get other types of measurements, a basic program using the SDI function must be used
(SdiCollect does not work, so data must be parsed by the program).
The block scales the outputs according to the values of
Slope
and
Offset
using the equation
output = reading*slope+offset.
The user can change the units for all the outputs by changing the
Units
field to the desired value.
The block supports calibration from the Sensors page. For the calibration, the user will enter the
current value sensor. The system will then adjust the offset so the desired value is obtained.
