Robust and safe

Industrial flame detector IFR 400

Rugged compact flame detector for harsh industrial applications where continuous operation is required. The IFx series features a robust die-cast aluminum housing with IP65 protection. Due to the housing concept, the device can be quickly replaced on site.
The compact flame detector is designed for industrial systems in an IP65 metal housing that require cost-effective monitoring without a large range of functions. The IFx series is divided into two basic types: the IFC for axial alignment and the IFR for radial alignment. The radial view design allows the mounting of a permanently functional flame detector at the positions of a monobloc burner normally reserved for intermittent flame sensors.

In addition to the usual design of the signal output with relay contacts for a PLC control or suitable automatic ignition systems, we also offer an ionization simulation that can be operated in continuous mode. The IFx400 can be used directly in systems that provide only an ionization flame monitor but require optical monitoring for certain reasons.
With the help of the IFx-COM evaluation tool, you can read out and save all information in the flame monitor. A good analysis of the upcoming flame and its monitoring quality is thus easily possible.

  • Continuous operation
  • 3-channel flame signal evaluation
  • Cost-effective monitoring for standard applications
  • Output signal either potential-free relay contacts or ionization simulation
  • Different designs for optimal alignment with the flame - IFC axial and IFR radial
  • CE certified, stand-alone flame detector - easy implementation of the flame detector

The IFR 400 is a compact flame detector specially designed for use in industrial combustion systems for continuous operation. It provides a galvanically isolated changeover contact as output. Flickering of the flame is used as a safety-relevant criterion for flame detection. Switching thresholds, switching times and filter characteristics can only be set by the manufacturer.

Flame detection is signalled by an LED and data is transmitted for evaluation. The compact flame controller IFR 400 may only be operated with a burner control unit or a DCS. It is not approved for direct control of the fuel valve!

    It comes together what belongs together - Merger of the BST Solutions GmbH with BFI Automation Mindermann GmbH

    Dear Ladies and Gentlemen,

    Already in July 2021 BFI Automation Mindermann GmbH and BST Solutions GmbH have jointly created the brand name FLAMONITEC® in order to increase awareness especially outside Europe.

    Hereby, we want to express our core competence in short form: Flame Monitoring Technology. And this in the entire bandwidth.

    Since 2004, BST Solutions GmbH has been active in the field of flame monitoring for original equipment manufacturers of heating technology and industrial firing equipment. For this BST Solutions GmbH uses the experience and patents of BFI Automation Mindermann GmbH, which has been active in the field of flame monitoring for power plants, petrochemical plants and gas turbines since 1973.

    These experiences have encouraged us to cooperate more closely also economically. On 31.05.2023 BFI Automation Mindermann GmbH has taken over all shares of BST Solutions GmbH retroactively to 01.01.2023.

    Both companies merge to form BFI Automation Mindermann GmbH.

    Through this merger, all business activities will be transferred to BFI Automation Mindermann GmbH with immediate effect. As part of this change, you can expect a seamless transition in our day-to-day business. Our dedicated team members will continue to serve you with the same level of professionalism, efficiency and attention to detail.

    We are confident that this change will help us serve you even better and provide you with even greater value in the flame monitoring field.

    Please do not hesitate to contact us personally for further information.
