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.
Benefits
Push-in terminals allow fast instrument installation or maintenance without tools
Convenient parameter setting with free software (requires FXA291 or TXU10)
Transmitter-sensor matching at critical measuring points based on Callendar-Van Dusen linearization coefficients
Optimized resistance thermometer measurement accuracy of up to 0.1 K with high long-term stability
Diagnostic information in accordance with NAMUR NE 107
Plug & play: supports factory pre-configuration
Applications
Reliable, highly accurate temperature measurement in combination with various industrial and hygienic versions
Approved for use in Zone 2 (Ex ec) / Div. 2 hazardous areas
Input: one Pt100 or Pt1000 (two-wire, three-wire or four-wire) resistance thermometer input
Output: 4...20 mA analog output
Pre-configured instrument parameters or factory parameter setting
Installed in a type B terminal head in accordance with DIN EN 50446
