HMDW110 series transmitters offer several output parameters. Relative humidity (RH) and temperature (T) are the measured parameters, the others are calculated based on RH and T.

Description

Temperature

T

°C

°F

Temperature in Celsius or Fahrenheit scale.

Relative humidity

RH

%

Ratio of the partial pressure of water vapor in the air to the saturation vapor pressure of air at current temperature.

Dew point

Td/f

°C

°F

Temperature at which the water vapor in the air will condense into water at the current pressure. When the dew point is below 0 °C, the transmitter outputs frost point (Tf) instead of dew point.

Enthalpy

h

kJ/kg

BTU/lb

Sum of the internal energy of a thermodynamic system.

Wet bulb temperature

Tw

°C

°F

The minimum temperature that can be reached by evaporative cooling in the current conditions.

Check the type label on your transmitter to verify its output parameters and scaling of the output channels.
