Page 5: General
CS105/CS105MD Barometric Pressure Sensor 1. General The CS105 analog barometer uses Vaisala’s Barocap® silicon capacitive pressure sensor. The Barocap sensor has been designed for accurate and stable measurement of barometric pressure. The CS105 outputs a linear 0 to 2.5 VDC signal that corresponds to 600 to 1060 mb. It can be operated in a powerup or continuous mode. -

Page 10: Programming
4. Programming 4.1 CS105MD Programming the MetData1 station for the CS105MD is done through Campbell Scientific’s Short Cut program. Short Cut includes code in the .DLD file to correct for elevation. 4.2 CS105 Atmospheric pressure changes little with time. In most weather station applications measuring pressure once an hour is adequate. - Page 11 CS105/CS105MD Barometric Pressure Sensor Example 1.

Page 15: Correcting Pressure To Sea Level
Sea level correction is automatically coded into datalogger programs when using Short Cut. 7. Maintenance There are no user-serviceable parts on CS105. Vaisala recommends recalibrating the CS105 every year. Contact Campbell Scientific, Inc., phone (435) 753-2342, for an RMA number before returning the sensor for recalibration. - Page 16 CS105/CS105MD Barometric Pressure Sensor This is a blank page.

Page 17: Daily Average
Appendix A. Daily Average If the CS105 will be measured every minute or faster, and a daily average is required, follow Example 5. In Example 5 the daily average, maximum, and minimum pressure is recorded at midnight. A constant is subtracted from the pressure before the average instruction is executed. - Page 18 Appendix A.
