There is a function in LabVIEW that allows measurement the humidity in the furnace?

Hi,

Can you please give more details on your system? How is the furnace built? What sensors are in it? There is no function like ReadHumidity(), but if you have a humidity sensor, you can read data from it according to the sensor's API (the communication protocol with the senor).

Good luck,

Danielle

Hi Danielle,

Thank you for your answer.

We built a system with 3 thermocouples that we put in three diffrent places in the furnace. In LabVIEW we were able just  to do the 3 thermocouples and we want to know how to add coordinatesn(X,Y,Z) to this thermocouples for measuring the temperature in a specific place-the location of the thermocouples in our furnace.  Back to the sensor humidity, we don't have humidtiy sensor there is no another way?

Maybe you can help us and tell us how to do the coordinates.

Thank yoy again, Kobi and Meital.

How do you expect to get the humidity level from the furnace to the computer/controller?

Assuming Kobi and Meital don't expect LabVIEW to have a PHD physicist that will run a thermodynamic simulation on their system inside included with their LabVIEW license I guess the scenario is as follows: 

1. They bought a furnace.

2. They placed 3 thermocouples that came with the furnace.

3. They understood from the manufacturer that via those thermocouples they can simulate the temperature at XYZ and the humidity using LabVIEW. 

The question then would be: Is there a driver for LabVIEW from the manufacturer on the manufacturer page or on the IDNet https://www.ni.com/en/support/downloads/instrument-drivers.html 

If this is not the case I don't think we can give a thermodynamic course about engines.

Moreover, it should be clarified that LabVIEW is best to collect the data and control hardware using some logic or a scientific theory. 

It can run a simulation like Matlab can but not as dedicated tools do and in most cases it won't give you a readymade solution, just the tools to find one.

For example, thermal conductivity of different materials can be simulated in LabVIEW if you input the teory and low level program a simulation, just like you would in Matlab.

In other thermal dedicated tools like Comsol you could probably enter the CAD design of the furnace and see the thermal conductivity simulation prebuilt into the tool and then move the results to LabVIEW as a predictive algorithm in a sub vi using maybe some Kalman filter in between or a fuzy logic control.

Beside that, LabVIEW has a tool called System Identification that can learn your data coming from the furnace to give you a neural network fit to the specific system you are working on using some data you collected.

I hope that it was helpful, 

Enjoy.
