Bimetallic and combined ammeters are especially intended for thermal monitoring of transformers, cables and other electrical devices which have a slow reaction to current changes. They indicate the mean rms current value during the measuring period of the meter (8 or 15 min.). These meters do not react to short current pulses essentially. The range of these meters can be enlarged by means of external measuring current transformers which are also offered by LUMEL and can be delivered on request if the meter is ordered in the option enabling a direct assembling on the current transformer. Features : - direct measuring range : I = 0...6A - measuring range with current transformer: I = 1 A or 5 A, - accuracy class: bimetallic movement: 3 - fixing in the panel Borna Niroo Karan (Bornika) is the exclusive agent of LUMEL in the fields of consultation , sales and distribution of power industry products including Bimetallic ammeter products .
