Description
The measuring value amplifier AD-MV 50 GX (for 2/3 lead technology) or
AD-MV 54 GX (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 18-30V DC. The power supply is independet of polarity.A
high packing density is achieved due to its narrow build.
Temperature range and output must be defined when ordering
equipment.
Application
Temperature measuring with Pt 100 temperature transmitter for
continuous transformation of temperature variables to analogue signals.
