Electronic measured 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
·Paperless recorders : the electronic alternative to (hybrid) paper strip chart recorders
·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.
By using various forms of interfaces they can be integrated into state-of-the-art topologies for measured data recording and process automation. High resolution colour graphic displays make it possible for paperless recorders and data managers to be used for front end process sequences and therefore swift on site reaction.
Mathematical and logical combinations enable complitcated calculations as well as automatic analysis of the measured signal.
