Direct reading of the pressure difference with pointer-scale indication. The higher pressure of the two pressure lines is indicated with the normal pointer, the lower pressure with the pointer-scale.
To ensure good readability, the differential pressure should not be less than 1/6 of the end scale value, e.g. with an end scale value of 60 bar, the measured differential pressure should be >10 bar
Two successively positioned parallel spigots for the connection of the two pressure lines with adjusting nut
Highly corrosion and chemical resistant, suitable for aggressive ambient conditions and gaseous or liquid measuring media that are non-crystallising and non-viscous
The required reading range is to be selected in line with the maximum occurring total positive pressure
In recirculation mode - e.g. closed loop heating system - the maximum overall pressure corresponds to the hydrostatic pressure including pump pressure
The maximum indicatable differential pressure on the graduated dial is 50% of the end scale value
