Configuration with compact instrument
As described under "2 Product description" the compact instruments are equipped with an integral processing of
measuring data. A current output 0 … 20 mA is available.
First of all each compact instrument must have a voltage supply. The current output can be directly connected to
indicators or process control systems.
2 Product description
The indicating and operating surface VEGA Visual Operating, installed on a PC ensures a simple and comfortable
configuration as well as operator supporting parameter adjustment of the compact instruments.
Therefore it is necessary to connect the computer via VEGACONNECT directly with the respective compact instruments.
A digital signal is superimposed to the current output. The adjustment of the sensor can be also carried out via the
current output. For indication and processing systems with an inner resistance of less than 100 Ohm a respective series
resistor must be connected for the time of adjustment.
