Overview
The CS106, manufactured by Vaisala, measures barometric pressure for the range of 500 to 1100 hPa (mBar). This range equates to from below sea level (as in a mine) to over 15,000 feet above sea level. Designed for use in environmental applications, the CS106 is compatible with most Campbell Scientific dataloggers.
Benefits and Features
Optimized to mount in Campbell Scientific enclosures
Integral switching circuit limits power consumption to measurement cycle
Three-year warranty
Detailed Description
The CS106 uses Vaisala’s BAROCAP silicon capacitive sensor to measure barometric pressure. It is encased in a plastic shell (ABS/PC blend) fitted with an intake valve for pressure equilibration.
The CS106 outputs a linear signal of 0 to 2.5 Vdc, which allows the barometer to be directly connected to a Campbell Scientific datalogger. An internal switching circuit allows the datalogger to power the CS106 only during measurement, which reduces power consumption.
