.AixLib.Fluid.Sensors.RelativeHumidityTwoPort

Information

This model outputs the relative humidity of the fluid flowing from port_a to port_b. 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.

If the parameter tau is non-zero, then its output is computed using a first order differential equation. Setting tau=0 is not recommend. See AixLib.Fluid.Sensors.UsersGuide for an explanation.

Revisions

• February 21, 2020, by Michael Wetter:
  Changed icon to display its operating state.
  This is for #1294.
• January 26, 2016 by Michael Wetter:
  Added quantity attribute for mass fraction variables.
  Made unit assignment of output signal final.
• January 18, 2016 by Filip Jorissen:
  Using parameter tauInv since this now exists in AixLib.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor. This is for #372.
• June 3, 2011 by Michael Wetter:
  Revised implementation to add dynamics in such a way that the time constant increases as the mass flow rate tends to zero. This significantly improves the numerics.
• Feb. 5, 2011 by Michael Wetter:
  First implementation.
