UNIVERSAL PROGRAMMABLE PROCESS CONTROLLERS

Protherm controllers feature an advanced process controller and a full-color display with customizable graphics. Models are available with an industrial touchscreen interface, or an advanced control knob interface for dirty applications, or where operators wear gloves. Optional modeling and target control can take heat treatment recipes to the next level. Detailed PID tuning features including multiple PID sets allow tuning of even the most dynamic control loops. Available as a stand-alone “light solution” or as part of a control retrofit. Custom applications are also available. Installations are carried out on new or refurbished furnaces and are used for updating existing systems. See our Technology Solutions page for process-specific configurations and control packages.

    • Visual display of the connected furnace, chambers, different configured components (e.g.: furnace door, recirculation turbines, etc.), and the loads
    • Configured for 3 Internal PID loops, expandable to 32 control loops, to regulate configured process parameters such as furnace temperature, quench oil temperature as well as atmosphere parameters (e.g., carbon flow, carbon potential, nitriding potential, oxygen potential, and many others)
    • Can hold up to 32 PID control loops to regulate configured process parameters such as temperature, furnace pressure as well as atmosphere parameters (e.g.: carbon potential, nitriding potential, and oxygen potential)
    • Load-oriented treatments: real-time monitoring of jobs at all stages of the process and all chambers of the furnace
    • All process parameters can be configured with alarm limits
    • Notification and processing of alarms
    • An online diffusion calculation provides the capability to control the process using the required target values (e.g.: case depth, surface carbon content)
    • Process variables can be viewed and recorded with chart recorders
    • Log files in PDF and ASCII-CSV format can be downloaded to a remote computer for archiving
    • Up to 99 treatments and templates can be created and modified

Operating Characteristics

  • The control knob or Touch-enabled screen enables the user to select input fields and enter data
  • Function keys are used for accessing the most important functions
  • Users access to different functions is password protected
  • A PC keyboard can be connected through a PS/2 port

Integrated Web Server

  • A remote computer can be connected to the device through a standard web browser
  • The treatment logs in PDF format and in ASCII-CSV format are kept for 30 days. They can be downloaded and then further processed with any appropriate PC software (e.g. Microsoft® Excel)
  • A powerful Java-based configuration tool can be downloaded and installed on a local PC for configuring all the device parameters

Built-In Functions

  • A mathematical model for calculating atmospheric parameters from gas inputs and sensor values
  • Real-time carbon and/or nitrogen diffusion calculation
  • Hardness profile calculation based on chemical composition, carbon or nitrogen content in the material, and quenching parameters

Configurations

  • The control loops, furnace graphics, process variables, and more can be configured with a user-friendly proprietary configuration software
  • The set-up of the PID parameters and other control functions are accessed via the configuration key
