Data recording systems measure the connected input signals and extrapolate the information required for individual applications. This information is then displayed on the screen of the device and is also stored internally or on an exchangeable data storage medium. This process information can be stored, long term, by transmission to superior systems (e.g. PCs) and is therefore readily available at the touch of a button.
Depending on the process requirement and application the following can be used:
- Data logger: simple devices with integrated digital display
- Data manager: powerful devices for stand alone applications and integration into systems
Common to all these devices is that they operate virtually free of wear and tear (no pens and paper) therefore saving time and money.
