Active humidity transmitter and temperature sensor for duct mounting

The SDC-H1T measures relative humidity with a unique capacitive sensor element. The applied measuring technology guarantees excellent reliability and long term stability. Using a display and programming accessory, the user has the option to read out and reset minimum and maximum values.

The sensing element for the temperature is either a glass packed thermistor with a negative temperature coefficient, a platinum film or nickel thin layer based probe. Its resistance changes according to the temperature. The change follows a specified curve.

Applications

• Humidity and temperature measurement for supply and return air ducts in heating, ventilation and air conditioning applications
• Recording of minimum and maximum values for critical environments
• Supervision of critical humidity and temperatures
