E+H iTEMP TMT31 Head Mount Temperature Transmitter

The E+H iTEMP TMT31 head mount temperature transmitter provides temperature measurement for various industrial and hygienic process applications. Configurated options include push-in terminals for tool-free wiring during installation. Transmitter-sensor matching is done using Callendar-Van Dusen linearization for critical measurement points​. Additionally, diagnostics information is done according to NAMUR NE 107.

Installation is done in terminal heads Form B as per DIN EN 50446. The device is available pre-configured or can be parametrized using free software tools (requires FXA291 or TXU10)​. There is a single RTD sensor input for Pt100 or Pt1000 (2-/3- or 4-wire) sensor and a 4 to 20mA analog output. The sensor is certified for use in Zone 2 (Ex ec) / Div. 2 areas.
