CS100 Barometric Pressure Sensor

The CS100 is a Campbell Scientific version of Setra's model 278 barometer. It uses Setra’s Setraceram capacitive sensor and IC analogue circuit to measure barometric pressure.  The CS100 includes a 0.76 m (2.5 ft) cable and a terminal strip for data logger power and signal connections. 

The CS100 is encased in a stainless-steel and polyester case fitted with a 1/8 in. barbed fitting for pressure connection. It includes an internal switching circuit that allows the data logger to power the barometer only during measurement, which reduces power usage.

Benefits and Features

  • Optimized to mount in Campbell Scientific enclosures
  • Low power consumption
  • 1 year against manufacturer defect
  • 500 to 1100 hPa (mBar) and 800 to 1100 hPa (mBar) versions also available by special order—contact Campbell Scientific
  • Integral switching circuit limits power consumption to the measurement cycle

The CS100 measures barometric pressure for the range of 600 to 1100 hPa (mBar). This range equates to from below sea level (as in a mine) up to 12,000 feet above sea level. Designed for use in environmental applications, the CS100 is compatible with all Campbell Scientific dataloggers.

  • CS100 Barometric Pressure Sensor measures barometric pressure over the 600 to 1100 MB range; extended barometric pressure range version is available
  • Three-year warranty
  • Low power consumption
  • Integral mounting bracket optimised for mounting directly to Campbell Scientific enclosures
