6 156. 25.. Principles of operation, construction The probe measures liquid levels , basing on a simple special relationship between the height of the liquid column Diaphragm option - SGM and the resulting hydrostatic pressure. The pressure measurement is carried out on the level of the separating level diaphragm of the immersed probe and is related to atmospheric pressure through a capillary in the cable. The active sensing element is a piezoresistant silicon sensor separated from the medium by an isolating plastic cup diaphragm. The electronic amplifier, which works in Capillary combination with the sensor, is additionally equipped with Black ( ).
