Working principle: the pressure is applied directly to a ceramic diaphragm, causing a deformation. This mechanical deformation is converted to an electric signal by means of dms-bridge located at the rear side. An electronic system is integrated in the set-up of the appliance, converting the dms – signals to electric standard signals – 4~20ma 0~10 vdc. Key features: 1.high accuracy 2.robust and compact design 3.overload protection 4.high vibration resistant 5.minimum hysteresis key specifications: 1.measuring range: -1.0 ~ 0.0 bar to -1.0 ~ -24.0 bar (max.
