The duct sensor of the GLT series has been specially designed for use in air conditioning and building services engineering. The stainless steel sensor tube is inserted into the ventilation duct. A sinter filter is located at the sensor tip, which effectively protects the sensor technology.

The evaluation electronics are located in a plastic housing on the back of the sensor tube. The connection terminals are easily accessible here. The output signal for the measured temperature and humidity can be 0-10 volts or 4-20mA (two-wire technology). In addition, the duct sensor is also available with a paper white display.

Fields of application:

  • Building control systems
  • Building automation
  • Ventilation ducts and ventilation systems
  • Process monitoring
  • Air conditioning and heating technology
