with chemical resistant, hydraulically isolated CrNi steel diaphragm for corrosive and aggressive liquids, gases media
Make: Fischer Messtechnik (Germany)
Model: DA10

Fischer DA10 is chemical resistant yet robust, wear resistant mechanism based pressure gauge. Due to its especially designed smoother internal surface pressure chamber without recesses and flush separating diaphragms, it can be implied to any type of aggressive or non-aggressive liquids or gases.
DA10 is direct differential pressure indicating instruments, suitable for installation in chemical, manufacturing, glass, fertilizer, offshore units etc.

Working Principle:

The pressures to be compared act by separating diaphragms hydraulically on the sensing diaphragm. The sensitive diaphragm will be in normal (equilibrium) position during equal pressure. Pressure differences deflect the sensing diaphragm to the lower pressure side.

The measurement is lead out of the closed measuring system using a torque rod and translated by the motion work to a 0 ~ 270 ° rotation angle.

When the measuring system is stressed one-sided beyond the measuring range, the separating diaphragms rest on identical shaped parts inside the system and protect the measuring system from overload.
