Omnigrad M TR10 - Modular RTD Thermometer

 

 

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

  • High degree of insert compatibility and design as per DIN 43772

  • Extension neck to protect the head transmitter from overheating

  • Fast response time with reduced/tapered tip form

  • Types of protection for use in hazardous locations: Intrinsic safety (Ex ia), non-sparking (Ex nA)

  • Head transmitter with easy selection: Analog output 4 to 20 mA, HART®, PROFIBUS® PA or
    FOUNDATION Fieldbus™

 

 

Field of application

  • Universal range of application

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

  • Pressure range up to 75 bar (1088 psi)

  • Degree of protection: up to IP68

  • Vibration-resistant sensor elements up to 60g
