iTEMP TMT182B temperature transmitter

The iTEMP TMT182B temperature head transmitter is designed for applications across all process industries that require accurate temperature measurements and HART® communication. The device provides valuable additional diagnostic information and stable measurement performance, helping to improve process efficiency and stable plant operation.

HART® temperature head transmitter with one universal sensor input suitable for use in hazardous areas. Temperature transmitter with HART® communication for the conversion of various input signals into a scalable, analog 4-20 mA output signal. Universal input for resistance thermometers (RTD), thermocouples (TC), resistance transmitters (Ω), voltage transmitters (mV). Reliability, long-term stability, high precision and advanced diagnostics for safe operations. Installation in terminal heads form B or cabinets.

Features

  • Universal input: supports RTDs (e.g., Pt100, Pt500, Pt1000), thermocouples (TC), resistance (Ω) and millivolt (mV) signals.
  • Output: 4-20 mA current loop with HART® communication protocol for configuration/diagnostics.
  • Installation: head-mounted (“terminal head form B”) suitable for direct mount on sensor heads.
  • High accuracy: for example, Pt100 input in range 50 °C to +200 °C has an accuracy of 0.14 K.
  • Diagnostics: supports sensor monitoring (open circuit, short circuit, wiring errors) and device self-monitoring, with diagnostics in line with NAMUR NE 107.
  • Ex / hazardous-area suitability: international approvals (ATEX, IECEx etc) for use in hazardous areas.
  • Power supply: Standard version 10-36 V DC; Ex-version 10-30 V DC.
  • Wide measurement range: e.g., for RTD inputs the device supports very wide spans (-200 °C up to +850 °C depending on sensor).
  • Galvanic isolation between input and output
