Differential pressure gauges
Function of a differential pressure gauge
The measuring chamber is separated trough a thin, corrugated metal membrane. Pressure will be the applied to both sides and additionally on one side there will be measuring pressure applied. Through a pass through bellow the bending of the membrane will be transferred to the movement. On the opposite side there will be a compensation to balance out the applied forces.
Differential pressure gauges are especially well suited to measure gaseous and fluid mediums that also can be aggressive. The display accuracy is ± 1,6% from the upper range level.
The admissible ambient temperature of the pressure gauge is between -20°C and +60°C. The maximum temperature of the medium shouldn’t be higher than 100°C.
