HMD65 Measurement Parameters and Default Analog Output Scaling
Table 1 shows the available output parameters and the default analog output scaling of the parameters for HMD65.
| Parameter | Default Scaling for 1 … 10 V Output Range |
|---|---|
| Relative humidity (RH) | 0 … 100 %RH |
| Temperature (T) | -20 ... +80 °C (-4 ... +176 °F) |
| Dew point temperature (Td) | -40 ... +80 °C (-40 ... +176 °F) |
| Dew point/frost point temperature (Tdf) | -40 ... +80 °C (-40 ... +176 °F) |
| Absolute humidity (A) | 0 … 300 g/m3 (0 … 131.1 gr/ft3) |
| Mixing ratio (X) | 0 … 600 g/kg (0 … 4200 gr/lb) |
| Wet-bulb temperature (Tw) | -40 ... +80 °C (-40 ... +176 °F) |
| Enthalpy (H) | -40 … 1600 kJ/kg (-9.5 ... 695.6 Btu/lb) |
Changing Measurement Parameter Scaling
If your application requires an analog output scaling that differs from the defaults shown in Table 1, you can configure the scaling by connecting the transmitter to Vaisala Insight PC software (requires Vaisala USB cable 219690).
