What is Differential Pressure Gauge?

Basically, differential pressure means that the pressure chamber will be separated by a thin diaphragm. This diaphragm is under constant pressure from both chambers and additionally has a gauge pressure from one chamber. The diaphragm will transmit pressure differences through the bellows on movement. The movement shows a positive or negative value on the dial with a 270° angle. The bellows on the opposite side compensates the force. Differential pressure gauges are used for measuring gases and liquids; It can be aggressive too. The accuracy is ± 1,6% of full scale deflection. The ambient temperature should be from -20 to +60 °C; and medium temperature not exceeding +100°C.
