CS215 Temperature and Relative Humidity Probe
8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the
PC to datalogger connection is active, you can click Finish in Short Cut
and you will be prompted to send the program just created to the
datalogger.
9. If the sensor is connected to the datalogger, as shown in the wiring
diagram in step 6, check the output of the sensor in the datalogger support
software data display to make sure it is making reasonable measurements.
5. Overview
The CS215 probe uses a single chip element that incorporates both a
temperature and an RH sensor. Each element is individually calibrated with
the calibration corrections stored on the chip. The element is easily changed in
the field. The ability to replace the element in the field reduces downtime and
calibration costs.
Electronics within the CS215 control the measurement made by the sensor
element, apply temperature and linearization corrections to the readings, and
present the data via SDI-12 to a datalogger.
A sintered plastic filter minimizes the effects of dust and dirt on the sensor.
The filter is lightweight and hydrophobic, thereby diminishing its effect on the
time response of the sensor.
The probe housing is designed to withstand permanent exposure to all weather
and to fit into a range of radiation shields, including compact shields.
