ACTIVE AND PASSIVE TEMPERATURE AND HUMIDITY TRANSMITTER DO 9861T, Merk : DeltaOhm
Keterangan
DO 9861T 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 R.H. sensor is temperature compensated. The instruments have two sensors, a capacitive sensor for measuring relative humidity and a Platinum resistive sensor (Pt100, 100 © at 100°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.The measurements refer to an atmospheric pressure of 1013.25 mbar. Once the physical quantity to be checked has been selected, the output current will be proportional and the status of the relays will depend on that variable.
