Extends from Buildings.Fluid.Sensors.BaseClasses.PartialAbsoluteSensor (Partial component to model a sensor that measures a potential variable), Modelica.Icons.RoundSensor (Icon representing a round measurement device).

Information

This model outputs the trace substances contained in the fluid connected to its port. The sensor is ideal, i.e., it does not influence the fluid.

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

Parameters

TypeNameDefaultDescription
BooleanwarnAboutOnePortConnection (from PartialAbsoluteSensor)trueSet to false to suppress warning about potential numerical issues, see Buildings.Fluid.Sensors.UsersGuide for more information
StringsubstanceName"CO2"Name of trace substance

Connectors

TypeNameDefaultDescription
Modelica.Fluid.Interfaces.FluidPort_aport (from PartialAbsoluteSensor)
Modelica.Blocks.Interfaces.RealOutputCTrace substance in port medium

Revisions

  • September 21, 2020, by Michael Wetter:
    Introduced parameter warnAboutOnePortConnection and updated documentation.
    This is for #1399.
  • February 25, 2020, by Michael Wetter:
    Changed icon to display its operating state.
    This is for #1294.
  • June 10, 2015, by Michael Wetter:
    Reformulated assignment of s and assert statement. The reformulation of the assignment of s was done to allow a model check in non-pedantic mode. This is for issue 268.
  • September 10, 2013, by Michael Wetter:
    Corrected a syntax error in setting the nominal value for the output signal. This eliminates a compilation error in OpenModelica.
  • February 22, by Michael Wetter:
    Improved code that searches for index of trace substance in medium model.
  • March 22, 2010 by Michael Wetter:
    Changed assignment for C so that Dymola 7.4 can find the analytic derivative.
  • September 29, 2009, by Michael Wetter:
    First implementation.
