INTELLIGENT TRANSMITTER TYPE: CARBO 47

 

 

 

SPECIAL FEATURES:

  • Calculates C-level from the residual oxygen content of gas or CO2-content from the furnace atmosphere
  • Converts the L-probe voltage to the voltage curve of a zirconium oxide probe
  • Parameter input via plug-in terminal
  • Menu-guided operation
  • High operation per galvanic separation of all inputs
  • Optional connection of two thermocouples Type “K” and “S”
  • Additional input for CO-analyzer
INTELLIGENT TRANSMITTER TYPE: CARBO 47

FUNCTION

The Carbo 47 is an intelligent transmitter designed for connecting different types of sensors. The unit processes the input signals and outputs the desired output variable as a voltage or current unit signal.

The versions described here convert the residual oxygen content of the gas to other components such as C-level based on the assumed gas equilibrium.

Determination of the C-level in conjunction with a conventional controller enables a favorably priced system for controlling carbon atmospheres in heat treatment plants.

The system still contains the facilities offered by more expensive systems, such as actual value correction (see below). The investment is soon amortized even on smaller furnace systems.

Another practical function of the unit is the conversion of the L-probe voltage into the probe voltage of a conventional zirconium oxide probe (see the appropriate datasheet for the L-probe). This allows the cheaper, more robust L-probe to be adapted to existing control systems.
