CS100 Barometric Pressure Sensor Description：

Product Manual Datasheet

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 data loggers.

Detailed Description

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 iincludes 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.

Benefits and Features

Optimized to mount in Campbell Scientific enclosures

Low power consumption

Three-year warranty

Integral switching circuit limits power consumption to measurement cycle
