Bimetallic instruments (maximum demand ammeters) are specifically suitable for thermic control of cables, transformers, etc. Due to the inertia of the system, the instrument is not affected by brief current pulses. The system consists of 2 mechanically connected bimetallic spiral springs. One of the spiral springs is heated by the measuring current and consequently expands according to the temperature, which gives a quadratic scale graduation. The other spiral spring expands in the opposite direction, compensating for changes in the ambient temperature. The instrument is provided with a red maximum-reading pointer. This pointer can be reset to the position of the black pointer by means of a knob on the front of the instrument. Features : - 3.0 accuracy class - 90° pointer deflection - IP52 protection - Approved by classification societies - Scale: always 120% of the current transformer - Measuring range: 0...6A or 0...1.2A - DIN standard sizes: Q48, Q72, Q96 - Exchangeable scale Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Bimetallic Instrument products .
