AD-MV 50 GL, AD-MV 54 GL


The measuring value amplifier AD-MV 50 GL (for 2/3 lead technology) or AD-MV 54 GL (for 4-lead technology only) converts the measuring signal issued from a resistance generator Pt 100 (according to DIN IEC 751) to an impressed output signal (i.e. 0-20 mA or similar). The output characteristic curve is issued temperature linear. When using the 3-lead switching lead, resistance up to 100 Ohms are compensated. In 2-lead switching a subsequent zero alignment and full alignment via trim potentiometers at the front is possible. The analogue output signal is galvanically separated from the supply voltage. A highly efficient, integrated electronic wide-range power pack (ALLPOWER) enables operation with 20-253V DC and 50-253V AC. There is no possibility of cross polarity of the connection voltage. A high packing density is achieved due to its narrow build.
