Description
Used for measuring pressure and vacuum of crystallizing, viscous or corrosive fluids. The sensing element is a diaphragm with concentric corrugations actuating the amplifying mechanism through a pivot. Possibility of mounting a third flange that allows inspection and cleaning of the sensing element.
Applications
Used for low pressure corrosive media where protection from the media is required.
