Comprehensive and common temperature measurement technology for almost all branches of industry

The high modular and robust thermometer finds its use in several applications in almost all industries. An optional head transmitter, with all common communication protocols, makes the device ready to use with enhanced measurement accuracy and reliability compared to directly wired sensors. A variety of process connections, dimensions and materials offer flexible application possibilities.

  • Benefits

    • High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths

    • Variable total length in suitable thermowells thanks to compression fitting on extension neck

    • Types of protection...

  • Field of application

    • Universal range of application

    • Suitable for installation in already existing thermowells

    • Measuring range: -200 to +600 °C (-328 to 1112 °F)

    • Degree of protection up to IP68
