.BuildingSystems.Fluid.Sensors.RelativeHumidity

Information

This model outputs the relative humidity of the fluid connected to its port. The sensor is ideal, i.e. it does not influence the fluid.

Note that this sensor can only be used with media that contain the variable phi, which is typically the case for moist air models.

To measure relative humidity in a duct or pipe, use BuildingSystems.Fluid.Sensors.RelativeHumidityTwoPort rather than this sensor. Read the BuildingSystems.Fluid.Sensors.UsersGuide prior to using this model to see about potential numerical problems if this sensor is used incorrectly in a system model.
