ABSTRACT:
A differential pressure transducer unit with an overload protection system to measure slight differential pressure in liquids and gases under high static compression loading, which unit can be connected by flanges to the differential-pressure lines. To avoid disturbing influences on the measuring element caused by radial tensions of the means of the overload protection system dependent on the absolute pressure, the measuring element is fasten in a cutout of the measuring-element housing so that it can oscillate and is free from tension. Each insulation plate is fitted with an eccentrically located measuring duct through which pressure-measuring agent flows, and which is connected at least indirectly to the measuring element.
