Differential Pressure Gauge DA30 measures and indicates pressure and differential pressure. It is suitable to work with gaseous and liquid media not affecting the materials used. Electrical and electronic accessory components (KE...) enable limiting of signal and transmitting of measurement. Fields of Application are water treatment, level measurement, filter technics, flow measurement. The DA30 is based on a rugged and uncomplicated diaphragm movement, suitable for pressure and differential pressure measurements. In a state of equilibrium, forces of springs on both sides of the diaphragm are balanced. The pressure or differential pressure to be measured creates an unbalanced force of springs for the measuring range until a new equilibrium is reached. When subjected to excessive pressure, the diaphragm rests on metal supporting plates. A centre-mounted torque rod transfers motion of the diaphragm system by an eccentric tilted axle through a torsional socket outwards. The axle rotation is transmitted to the dial by a lever.
