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
Suitable for gaseous, low-viscosity and non-crystallising measuring media that do not corrode brass
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
