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.
