Açıklama

SPECIAL FEATURES:

 

  • The menu-guided operation, plain text
  • Foil keyboard
  • Exact control
  • Connections of one thermocouples Type “S” or “K” by choice
  • Program memory with 99 setpoint programs for K – and process temperature N (time-synchronous)

  • All inputs and outputs 4…20 mA (unless thermocouple)
  • Directly adaptation of flowmeter controller for NH3, N2, CO2, or endogas
  • 2 ammonia flowmeter controllers for small or great quantity are choosable (thereby high precision)
  • Limit of control variable at ammonia quantity are separate possible
  • Possibility for initial gas

    • Serial interfaces (RS422/RS485)
 

CONTROL SYSTEM NITROMAT-KN

 

FUNCTION

The Nitromat-KN is a measuring and control system for exact furnace atmosphere-control in nitriding- or nitrocarburizing processes.

The 99 program controls of process-temperature and KN -values, with free eligible program time- tracks and analogous outputs for NH3 – N2 -Endogas- CO2, by mass-flow controls enable an exact control of gas-nitriding processes.

A controlled N2 – thinning of the Nitriding atmosphere is possible. By use of the initial gas, it is possible to reduce the complete treatment time.

In connection with the program time tracks and a program selection, in addition, a pre-oxidation of the components is possible.
