HD 9408T BARO HD 9408TR BARO HD 9908T BARO HD 9408TR BARO offers superior temperature performance: the internal circuitry allows the sensor to work at constant temperature so that it achieves accurate temperature compensation over the whole range from -40°C to +60°C. HD 9408TR BARO requires a continuous dc power supply and a differential cabling connection to achieve best results. It is available in different output versions: 0÷1 Vdc, 0÷5 Vdc (1÷5 Vdc, 1÷6 Vdc on request). HD 9908T BARO, unlike the other models, is equipped with a display showing the pressure measurements, an analog output...

The measurement of the barometric pressure in free field can give incorrect values of hundred pascal fluctuation and wind direction. With the static port for barometric measurements, HD9408PS 50 can minimize these errors because, in addition to act as a filter (brake) against the dynamic pressure of the wind, the barometer can operate correctly even in the presence of snow or ice and comply with the recommendations of the WMO (World Meteorological Organization). The materials used for th construction of the static are UV resistant and can operate in temperatures between -40°C and +80°C....

An out-of-standard temperature operating range can be requested when placing the order. Important Warning: probes work in the -40°C…+80°C temperature range. Outside this range data are not correct; electronics is designed to operate in this range. SENSORS The humidity sensor is a condenser which dielectric is made up by an hygroscopic polymer. As water dielectric constant is approximately 80, you’ll get a strong change in capacity as the humidity content of this polymer changes. The advantages of this kind of sensor are: good linearity, insensitivity to temperature changes, fast response...

PROGRAMMING HD9008TRR and HD9009TRR relative RH and temperature transmitters are factory calibrated. The HD9008TRR is provided with a 4…20mA current output, while the HD9009TR with a 0…1Vdc voltage output. In the HD9008TRR standard configuration, 4mA correspond to 0%RH and -40°C, while 20mA equal 100%RH and +80°C. In the HD9009TRR one, 0Vdc corresponds to 0%RH and -40°C, while 1Vdc equals 100%RH and +80°C. The user can re-calibrate the RH probe holding the 0%…100%RH range and setting a different range for temperature, as long as it is within -40 and +80°C limits. Figure 4 shows the...
