Description Technical Specifications Downloads Vendor

Digital temperature transmitter Model T38

  • T38 temperature transmitters are designed for universal use in the process industry including measurements along the complete hydrogen value chain
  • Temperature measurement of liquid hydrogen (down to -258°C) is possible in combination with various WIKA temperature sensors
  • They offer high accuracy through sensor-transmitter matching, highest reliability and excellent protection against electromagnetic influences.
  • Via HART® protocol, the T38 temperature transmitters are configurable (interoperable) with a variety of open configuration tools. In addition, the T38 temperature transmitters, via the WIKAsoft-TT configuration software with model PU-548 programming unit, can be parameterised very easily, quickly and with a clear overview.
  • Besides the selection of the sensor type and the measuring range, the software enables the error signalling operation, damping, several measuring location descriptions and process adjustment to be stored.
  • The T38 transmitters offer a wide range of sensor connection combinations. Through the configuration of a sensor with redundancy (dual sensor), on a sensor failure it will automatically change over to the working sensor.
  • Furthermore, there is the possibility to activate sensor drift detection. With the WIKA True Drift Detection technology, sensors can be monitored continuously, and erroneous measuring locations can be identified immediately.

Key features

  • Measures up to -258 °C
  • Higher accuracy
  • Highest reliablility
  • Protection against electromagnetic influences

Application areas

  • Cryogenic hydrogen
  • Hydrogen prodcution
  • Hydrogen refueling station
