Manometer Preiss EMPEO-KBM DIFFERENTIAL PRESSURE GAUGES TYP DIP1CH100-3, 160-3 This data sheet contains all important features of models DiP1Ch and DiPChG with ordering information. Apllication: The differential pressure gauges models DiP1CH and DiPChG are used for direct indication of low differential pressure from 0 - 40 mbar and above at static pressure of 40 bar (600psi) or optionally 100 bar (1500 psi). They may be used for measuring fluid or gaseous media, which are compatible with stainless steel 316 Ti, 316 L and Viton. The measuring chambers are flushable, therefor they are intensitive to the accumulation of solid particles. 2 x flush and ventilation connections 1/8“ BSP female are standart supply. Different electrical accessories can be installed, such as limit switch contact assemblies and capacitive electrical transformers. Construction und Function: The measuring system consists of two pressure chambers, each fitted with a measuring diaphragm which are connected by a connecting rod. The space between the two diaphragms is liquidfilled to compensate the static pressure. In case of balanced pressure both measuring diaphragms are in their position of equilibrium. In case of differential pressure a force is created on the diaphragms which causes a deflection in direction with the lower pressure. The connecting rod transfers this deviation of the measuring diaphragms to the transfer-lever that is mounted on the measuring shaft. The measuring shaft causes a rotation proportionally to the differential pressure which is transmitted by the movement to and analogous move between 0 and 270°. In case of one-sided force acting on the measuring system and exceeding the measuring range overpressure protection becomes active. Due to the overpressure a collar mounted on the connection rod will be pressed against an internal O-ring which prevents the transferring of the overpressure to the opposite diaphragm. That way two seperated pressure rooms are built up. Inside of the liquid filled room between the overloaded diaphragm and the Oring a counter pressure equivalent to the overpressure will be built up which protects the strained diaphragm. The forces acting on the diaphragm will be compensated.
