  • Clever simplicity:
    One controller for all parameters and applications, intuitive user interface, automatic sensor recognition, hot plug & play with pre-calibrated Memosens sensors.
  • Highest flexibility:
    Universal modules for all parameters minimize spare part stock and allow for easy 1-click extension to up to 8 channels at any time.
  • Seamless system integration:
    Unique portfolio of communication standards suits every distributed control system (DCS).
  • Simple and safe commissioning:
    Saving configuration on SD card enables fast set-up on duplicate installations.
  • Process control from a distance:
    Integrated web server that allows the operator to remotely view diagnostic data, perform configurations, or access device parameters in any web browser - even via Smartphone.
  • Higher availability, lower costs:
    Heartbeat Technology enables status-oriented maintenance and easy verification of the entire measuring point and helps to carry out optimization measures.
