Campbell CS100 Barometer

Campbell Sci – CS100 Barometric Pressure

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 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 an 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.
