Acquiring data with a CR800 datalogger requires integration of the following into
a data acquisition system:
• Electronic sensor technology
• CR800 datalogger
• Comms link
• Datalogger support software
(p. 86)
A failure in any part of the system can lead to bad data or no data. The concept of
a data acquisition system is illustrated in figure Data Acquisition System
Components
(p. 53) Following is a list of typical system components:
• Sensors
(p. 35) — Electronic sensors convert the state of a phenomenon to
an electrical signal.
• Datalogger
(p. 36) — The CR800 measures electrical signals or reads
serial characters. It converts the measurement or reading to engineering
units, performs calculations, and reduces data to statistical values. Data
are stored in memory to await transfer to a PC by way of an external
storage device or a comms link.
