temperature

[ppatel326]

I was wondering how to add the temperature panel that will be able to be configured to a certain resistor. My program requires an alarm to be set off at 45 C, while showing the temperature of the water.  I am not sure how to make it so that the panel will show the temperature change over time.

I don't understand this sentence at all.  What is a temperature panel?  What resistor are you talking about?  What do they have to do with each other?

If you want to track a value over time, look at a waveform chart.

You have a lot of unusual structures in your code.  You have a couple of boolean to 0:1 functions which you are multiplying by a -1 and comparing to zero.  A lot of conversion and math for what should be some simple boolean logic.

I was basically wondering how I would be able to set up a program to watch a temperature change from a change in voltage.  The reason that there is a -1 voltage leaving the program is due to the fact that I needed to shut down a function generator, which required a -1 Volt peak to peak to be send to the Input section of the generator.  What I need from this program is a way to see a temperature change when a voltage changes.  The temperature reading must be in a numerical valve and represent the temparture of a certain water tank from a thermistor.  The thermistor changes resistance, which can be converted into a change in voltage, thus all i need from Labview is to set off an alarm at 45 degrees and also to show the temparture valve.  SOMEONE PLEASE HELP.

Why does the user name change, but not the question? Is this some kind of homework? Maybe the same work for the whole class? And both users attaching the same vi?

I am currently working with ElVis to find the voltage change in a thermistor and I need to like the voltage to temperature.  For example, if the voltage is 2 volts then the temperature is 31 degree, while at 2.1 it is 32, etc.  thank you

Hi KP2008,

you should be able to get the temp-voltage dependency on your own: you (should) know the type of thermistor and you should know its properties. So you should be able to write down a formula to calc temp from voltage or vice versa! Just look into the datasheet for this thermistor!
