PLEASE READ FIRST
About this manual
Please note that this manual was originally produced by Campbell Scientific Inc. primarily for the
North American market. Some spellings, weights and measures may reflect this origin.
Some useful conversion factors:
Area: 1 in2(square inch) = 645 mm2
Length: 1 in. (inch) = 25.4 mm
1 ft (foot) = 304.8 mm
1 yard = 0.914 m
1 mile = 1.609 km
Mass: 1 oz. (ounce) = 28.35 g
1 lb (pound weight) = 0.454 kg
Pressure: 1 psi (lb/in2) = 68.95 mb
Volume: 1 UK pint = 568.3 ml
1 UK gallon = 4.546 litres
1 US gallon = 3.785 litres
In addition, while most of the information in the manual is correct for all countries, certain information
is specific to the North American market and so may not be applicable to European users.
Differences include the U.S standard external power supply details where some information (for
example the AC transformer input voltage) will not be applicable for British/European use. Please
note, however, that when a power supply adapter is ordered it will be suitable for use in your country.
Reference to some radio transmitters, digital cell phones and aerials may also not be applicable
according to your locality.
Some brackets, shields and enclosure options, including wiring, are not sold as standard items in the
European market; in some cases alternatives are offered. Details of the alternatives will be covered in
separate manuals.
Part numbers prefixed with a “#” symbol are special order parts for use with non-EU variants or for
special installations. Please quote the full part number with the # when ordering.
Recycling information
At the end of this product’s life it should not be put in commercial or domestic refuse
but sent for recycling. Any batteries contained within the product or used during the
products life should be removed from the product and also be sent to an appropriate
recycling facility.
Campbell Scientific Ltd can advise on the recycling of the equipment and in some cases

CS106 Barometric Pressure Sensor
1. Introduction
The CS106 measures barometric pressure for the range of 500 to 1100 mb. This
range equates to from below sea level (as in a mine) to over 15,000 feet above sea
level. Designed for use in environmental applications, the CS106 is compatible
with all Campbell Scientific dataloggers.
Before using the CS106, please study
•Section 2, Cautionary Statements
•Section 3, Initial Inspection
•Section 4, Quickstart
More details are available in the remaining sections.
2. Cautionary Statements
•Warning: Failure to protect the sensor from condensation may result in
permanent damage.
•Warning: Improper wiring may damage the CS106 beyond repair.
•Care should be taken when opening the shipping package to not damage or
cut the cable jacket. If damage to the cable is suspected, consult with a
Campbell Scientific applications engineer.
•Although the CS106 is rugged, it should be handled as a precision scientific
instrument.
•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.
3. Initial Inspection
•Upon receipt of the CS106, inspect the packaging and contents for damage.
File damage claims with the shipping company.
4. Quickstart
4.1 Step 1 — Mount Sensor to an Enclosure Backplate
The mounting holes for the sensor are one-inch-centred (three inches apart), and
will mount directly onto the holes on the backplate of Campbell Scientific
enclosures. Mount the sensor with the pneumatic connector pointing vertically
downwards to prevent condensation collecting in the pressure cavity, and also to
ensure that water cannot enter the sensor.

4.2 Step 2 — Use SCWin Short Cut to Program Datalogger and
Generate Wiring Diagram
The simplest method for programming the datalogger to measure the CS106 is to
use Campbell Scientific's SCWin Short Cut Program Generator.
1. Open Short Cut and click on New Program.
2. Select a datalogger and scan interval.
