The iTEMP TMT31 is a single-channel temperature transmitter with high reliability and high long-term stability, outputting a 4...20 mA current signal. It is installed directly in a type B terminal head and is approved for use in Zone 2 / Div. 2 hazardous areas. Transmitter-sensor matching based on Callendar-Van Dusen linearization coefficients increases the measurement accuracy of resistance thermometers. Push-in terminals enable fast field wiring and instrument installation. The instrument can be pre-configured, or parameters can be set easily using free software.
