Temperature measurement

Raytek expands the modular MI3 infrared sensor series, adding communication boxes for integrating the digital temperature sensors into process control systems. In addition to Profibus and Modbus units and a version with four galvanically isolated analog outputs, there are models for Ethernet and Profinet IO, optionally with a robust die-cast zinc housing or 6TE DIN rail housing. The new Profinet boxes are suitable for time-critical applications as they can transmit data to a higher-level PLC in real time. The Ethernet version features a 64 MB data logger large enough for 24 days of recorded data at a one second saving interval. It supports TCP/IP4 and, based on an integrated HTTP server, provides its own landing page which enables direct access to the temperature data as well as product information and manuals via any standard internet browser.

A user-friendly control panel and a large LCD display facilitate on-the-spot configuration of functions such as peak and valley hold and intelligent averaging. Automatic head detection enables comfortable plug and play. DataTemp Multidrop software for remote operation and configuration is available free of charge. The MI3 system entails minimum commissioning costs per measurement point since up to eight sensors can be connected to one communication box. Users can choose freely from the whole MI3 program: all sensors and boxes are compatible. Various spectral models, high data quality, and the wide temperature range from -40 to 1,800°C make the MI3 system an excellent solution for many applications, especially in process monitoring.
