Features

Measures barometric pressure over 600 to 1060 mb range
Accuracy is ±0.5 mb @ +20°C
Integral mounting bracket optimized for mounting in CS enclosures
Integral switching circuit allows power consumption only during measurement cycle
Manufactured by Vaisala, Inc.

General Description

The CS105 Barometer uses Vaisala's silicon capacitive sensor to measure barometric pressure over a 600 to 1060 millibar range. The CS105 outputs a linear signal of 0 to 2.5 Vdc allowing it to be directly connected to Campbell Scientific dataloggers.

An integral circuit switches 12 volts from the datalogger to the barometer only during measurement, thereby reducing power requirements. Sensor warm-up and measurement time is one second minimum.

Note: The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
