Everywhere in industry electronic sensors are used to detect process values such as temperature, pressure or flow. Process value monitoring often takes place directly in the sensor. However, sometimes separate monitoring devices are required, for example if two measured values are to be offset against each other and the resulting value is to be monitored.
Calculating and evaluating measured values
The evaluation unit has various operating modes and two analogue sensors can be connected. This way, two switching points can be assigned to a measured signal, or a limit value can be assigned to two measured values. The two measured signals can be scaled and linked, with each other using mathematical functions, such as addition or subtraction.
The process value calculated in this way can be monitored with up to two switching points, and can be output as an analogue signal (4...20 mA). Measured values can be transmitted digitally to a higher-level controller via IO-Link. The device’s extensive parameter setting is also conveniently carried out via IO-Link.
