The ΔP-controller HE 5420 is used for differential measure- and control functions in air pollution control systems. The controller enables a ΔP-dependend cleaning through activation of a lower and an upper switch-point and an alarm-threshold for supervising the maximal differential pressure (ΔP-alarm).
The actual differential pressure or the switching points are displayed with an 3-digit digital seven segment display.
