Text in icons of sensors

[tobolar]

It should be harmonised which text is used in sensors.

• quantity name, like V in Thermal.FluidHeatFlow.Sensors.VolumeFlowSensor
• quantity unit, like A in Electrical.Analog.Sensors.CurrentSensor
• quantity text, like power in Mechanics.Rotational.Sensors.PowerSensor
• something else
• a combination of abovementioned

In electrical engineering we use the unit within the circular sensor symbol to indicate which meter it is. Therefore, for a power meter we use "W" to indicate it as watt-meter. How do other engineers indicate their sensors? I do not know.

[christiankral]

This issue is actually also linked to #2471 (comment), where I proposed color code (128,128,128) for descriptive text of an icon. The text of the unit / quantity / whatever should actually also use the proposed color code.

[christiankral]

Even the electrical sensors icons are not designed in the same way:

Thermal sensor of Modelica.Thermal.FluidHeatFlow and Modelica.Thermal.HeatTransfer shall also be harmonized:

This probably could be solved elegantly by having a proper base sensor icon class which allows for the label (e.g., P, I, V, dp, H, M) and maybe the optional m=... parameter.

[dietmarw]

As for unit vs. quantity. Maybe the display of [A] would make it more obvious that it is a quantity. Also since the sensors give a signal out it might help to actually have the unit and not quantity displayed. Since that is what the signal is "attached" to.

[beutlich]

Quantity might be less ambiguous than unit in case of unit ≠ displayUnit.

[HansOlsson]

Quantity might be less ambiguous than unit in case of unit ≠ displayUnit.

I agree that case of unit ≠ displayUnit is important, but I am unsure about the implication - consider Modelica.Fluid.Examples.DrumBoiler.DrumBoiler

It should be harmonised which text is used in sensors.

* quantity name, like _V_ in `Thermal.FluidHeatFlow.Sensors.VolumeFlowSensor`

* quantity unit, like _A_ in `Electrical.Analog.Sensors.CurrentSensor`

* quantity text, like _power_ in `Mechanics.Rotational.Sensors.PowerSensor`

* something else

* a combination of abovementioned

I totally agree. We need to come up with a decision. The majority of sensors in the MSL places a black label of the quantity next to the output(s) of the sensor. Personally I am used to indicate an Ampere meter by "A" not "i". For the sake of consistency I have no issue to switch to "i".

@AHaumer Do you have any objections against "i" for an Ampere meter?
