Technical Description

The CS100 is a Campbell Scientific version of Setra's model 278 barometer. It uses Setra’s Setraceram^TM 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.
