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 ofWaterperkg of dry air). The Temperatures are Expressed in Degrees Celsius. |

| Conductivity Transmitter / Controller |
|

DO 9786T / DO 9766T transmitters convert the output of a conductivity electrode into a signal, with temperature compensation, at 4 + 20mA.
The electrode input circuit is galvanically insulated against the 4 + 20mA output signal. An LCD indicator allows viewing of the process signal value and of the various parameters. The accurate design and choice of components make the instrument precise and reliable for a long working life.
The instrument works in conjunction with a conductivity electrode and a temperature probe (Pt100 sensor, 100 at OC). |
