  Description

The digital temperature measuring converter of series VarioCheck VC5B are freely programmable digital measuring transformer with two analogue outputs and up to 4 limiting value relays. The input of all characteristics is carried out via the configuration software AD-Studio. VarioCheck fulfils all tasks of a universal measuring value recording through integral function modules such as selectable relay functions, simulation modus, free linearizing curves and a wide range of supply voltage.

  Specific characteristics

  • Resistance thermometer inputs, types Pt/Ni 100, Pt/Ni 500, Pt/Ni 1000
  • Thermocouples inputs, types J, T, K, E, N, S, R, B, C or inputs a mV/T-characteristic curve. Selectable internal or external reference junction
  • A bipolar mV-Voltage input. Free linearizing curves possible.
  • Current- and voltage input different scaleable and simultaneously useful. Must not conntect the clamps 8 and 9.
  • Galvanic 3-circuit separation of input, output and supply.
  • Freely definable scaling of the quantity to be measured through stating range, decimal point position and unit from the list or defined unit.
  • Zoom function, expanded scale, linearizing, inverse modus.
  • Monitoring of the measuring signal with up to 4 freely adjustable limiting values.
  • Monitoring functions such as limiting values, window function or signal trend each with relay.
  • Non-volatile saving of all set parameters.
