Detailed Description
The CS100-QD 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-QD 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.
