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 and sanitary measurement
technology, such as differential pressure measurement between the supply and return lines in heating systems or for monitoring filters, fans, and
compressors.
