The readout unit is a tool enabled to power sensors and to display data from them. It is typically used when it is not possible or it is unintended to acquire automatically and continuously those data coming from transducers (by a remote acquisition unit). In order to make the reading operations faster, sometimes the signals of two or more sensors are grouped into centralized panels from which, connecting with the portable reading unit using the supplied cable and with the simple use of a channel selector, you can display data from all sensors installed. Models for reading all popular sensors are available on the market. The reading unit also comes complete with a connecting cable.
