DO 9861 T humidity and Temperature Transmitters convert the humidity and temperature measured by two sensors into a 4-^20 mA signal.
An LCD indicator allows the value of the process Signal and the various parameters to be displayed.
The accurate design and choice of components make the instruments precise and reliable for a long working life. The instruments have two sensors, a capacitive sensor for measuring relative humidity and a Platinum resistive sensor [Ptl 00, 1 0012 at 1 00 C) for measuring temperature.
The transmitters measure the Relative Humidity (%RH), the sensor Temperature (TC), and Calculate the Wet Bulb Temperature (WT), the Dew Point Temperature (DP), the Absolute Humidity (gr/m3) and the Mixing Ratio [gr/kg - grams of Water per kg of dry air). The Temperatures are Expressed in Degrees Celsius.
