CS100 Barometric Pressure Sensor
isolated metallic surfaces. One of the surfaces is essentially a diaphragm
constructed of a Setra’s proprietary compound of fused glass and ceramic
(Setraceram™) or a low-hysteresis material, such as 17-4 PH SS. The
diaphragm is capable of detecting a slight change in the applied pressure,
which is then converted to an analog voltage signal by Setra’s custom
Application Specific Integrated Circuit (ASIC). The analog signal generated
by the barometer can be directly measured by a Campbell Scientific datalogger.
The CS100 is supplied in the triggered mode, in which the datalogger switches
12 VDC power to the barometer before the measurement. The datalogger then
powers down the barometer after the measurements to conserve power.
Other measurement range options such as 500 to 1100 millibar, and 800 to
1100 millibar are also available. Please contact Campbell Scientific, Inc. for
ordering these special versions.
Campbell Scientific offers the CS100-QD, a version of the CS100 that includes
a connector for use with a RAWS-F or RAWS-P weather station (refer to the
RAWS-F and RAWS-P manuals for more information).
If the CS100 and datalogger will be housed in different enclosures, the
CABLE5CBL-L should be used instead of the cable that is shipped with the
CS100. The CABLE5CBL-L can terminate in:
• Pigtails that connect directly to a Campbell Scientific datalogger
(option –PT).
• Connector that attaches to a prewired enclosure (option –PW). Refer
to www.campbellsci.com/prewired-enclosures for more information.
