Abstract
The disclosure relates to a differential pressure transducer unit comprising an over-load protection system which is used to measure low differential pressure in liquids and gases under high static pressure load which can be connected to flanges on the working pressure lines. The differential pressure transducer unit consists of a planar multi-layered arrangement comprising layers which are conductive, insulating and which are insulated from each other, whereby the insulating and conductive layers comprises recesses which at least partially cover each other, wherein the measuring mechanism and the measuring value processing means are accommodated. At least one of the layers is a functional component of the over-load protection system.
