Relative humidity (RH)
is defined as the ratio of the water vapor pressure or water vapor
content to the saturation vapor pressure or the maximum vapor content
at the temperature of the air or gas. The saturation vapor pressure
in the air varies with air temperature, the higher the temperature,
the more water vapor it can hold. When saturated the relative humidity
in the air is 100 %RH. |

| ACI A/RH |
Relative Humidity transmitters, convert a resistance
change to a linear 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output. The current signal may be transmitted over long distances on twisted-pair wire and will not be affected by the lead wire resistance or electrical noise. 1%, 2%, 3%, and 5% Accuracies |
| A/RH-TEMP |
Relative Humidity transmitters, convert a resistance to a linear 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output. The current signal may be transmitted over long distances on unshielded twisted-pair wire and will not be affected by the lead wire resistance or electrical noise. |
