Special features

  • Cost-effective “2 in 1” temperature measurement
  • Compact design
  • Application ranges from -200 ... +700 °C
  • “Plug-and-play”, thus no transmitter configuration necessary



At any point where the process temperature must be displayed locally and there is a requirement to simultaneously transmit the signal to a central controller or remote control room, the model TGT73 intelliTHERM® can be used.

Through the combination of a mechanical measuring system and electronic signal processing, the process temperature can be read securely, even if the power supply is lost.

Due to the wide variety of possible designs, the model TGT73 gas actuated thermometers can be perfectly adapted to any process connection or location.

The adjustable stem and dial version can be adjusted to any angle to allow easy reading. With the contact bulb version (without direct contact with the medium), the temperature can be measured and controlled even when the pipe diameter is extremely small.

The WIKA electronic transmitter, integrated into the high-quality mechanical temperature gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display.

The measuring span (electrical output signal) is set automatically along with the mechanical display, i.e. the scale over the full scale range corresponds to 4 ... 20 mA.
