Evaluation electronics for
ceramic pressure sensors - DS-MOD-
Connection
The pressure sensor is connected to the four pin socket strip as
shown in the illustration. The connection cable can be directly inser-
ted into the spring contacts of the socket strip.
The connection of a Pt1000 is optional and only required, if the digital
setting with temperature compensation is being used.
The connection of operating voltage and instrument is done as shown
in the following diagrams:
