Item No. 1301-4131-0540-139
EAN 4 251325 612478

The pressure sensor ⁄ differential pressure sensor PREMASGARD® SHD 400 is used to measure above-atmospheric, below-atmospheric, and differential pressures in virtually neutral gaseous and liquid media. A rugged and non-sensitive ceramic pressure measuring cell is used. The measuring pressure acts on the ceramic membrane, causing it to deform. This membrane is fitted with a DMS bridge whose resistance value changes in proportion to the degree of deformation. The electronics integrated in the transmitter housing converts this change in resistance into a standard signal of 0-10 V or 4...20 mA. The process connection is implemented via two internal threads G ⅛ ". It is used in all areas of industrial of sanitary measurement technology, such as differential pressure measurement between the supply and return lines in heating systems or for monitoring filters, fans, and compressors.
