Cr300 Series Data Acquisition System Components - Campbell CR300 Series Product Manual

1. CR300 series data acquisition
system components
A basic data acquisition system consists of sensors, measurement hardware, and a computer with
programmable software. The objective of a data acquisition system should be high accuracy,
high precision, and resolution as high as appropriate for a given application.
The components of a basic data acquisition system are shown in the following figure.
Following is a list of typical data acquisition system components:
Sensors - Electronic sensors convert the state of a phenomenon to an electrical signal (see
l
Sensors (p. 3) for more information).
Data logger - The data logger measures electrical signals or reads serial characters. It
l
converts the measurement or reading to engineering units, performs calculations, and
reduces data to statistical values. Data is stored in memory to await transfer to a computer
by way of an external storage device or a communications link.
Data Retrieval and Communications - Data is copied (not moved) from the data logger,
l
usually to a computer, by one or more methods using data logger support software. Most
communications options are bi-directional, which allows programs and settings to be sent
