Specs at a glance

  • Accuracy

    (Pt100,Pt1000, -50…+250°C) <= 0,1 K
    (Pt100,Pt1000, -58…+482°F) <= 0,18° F

Field of application

The iTEMP TMT31 is a reliable, long-term stable, single-channel 4 to 20 mA temperature transmitter for thermometers with terminal head Form B suited for use in Zone 2 / Div. 2 areas. Individual transmitter-sensor matching with Callendar-Van Dusen linearization further improves your temperature measurement accuracy for RTD sensors. Push-in terminals for quick wiring facilitate installation. The device is available pre-configured or can easily be parametrized using free software tools.
