CAMPBELL SCIENTIFIC WHEN MEASUREMENTS MATTER CS100Barometric Pressure Sensor Standard Barometer Resides inside weather proof enclosure The CS100 measures barometric pressure for the range of use in environmental applications, the CS100 is compatible 600 to 1100 mb. This range equates to from below sea level with all Campbell Scientific dataloggers. (as in a mine) up to 12,000 feet above sea level. Designed for Benefits and Features J Optimized to mount in Campbell Scientific enclosures 1 Low power consumption ) Three-year warranty 1500 to 1100 hPa (mBar) and 800 to 1100 hPa (mBar) versions also available by special order—contact Campbell Scientific 1 Integral switching circuit limits power consumption to measurement cycle Technical Description The CS100 is a Campbell Scientific version of Setra's model 278 barometer. It uses Setra's Setraceram capacitive sensor and IC analog circuit to measure barometric pressure. The CS100 is encased in a stainless steel and polyester case fitted with an 1/8 in. barbed fitting for pressure connection. It includes an internal switching circuit that allows the datalogger to power the barometer only during measurement, which reduces power consumption.
