Configuring Custom Analog Inputs

[digur1977]

Hi All,
I faced the problem during set up new temperature/humidity sensor.
So the sensor type is Vector,I connected to it via T3000 and gave the value 0-10 V the button #46 but the reading value is strange.
I don’t understand what is the problem.
Can you help me

This is best handled by the custom analog input ranges. Here’s a link, follow the instructions there and report back here if there are problems.

Custom analog inputs

Here’s some screenshots showing how to configure transducers in general. From the inputs table, click in the range column at Tab1 to bring up the range setting dialog with the various sensor types available and select ‘Custom Range’ 50 at Tab2 which brings up another dialog where you set up the signal table. At Tab4 you see the settings to plug in for a typical 4-20ma or 0-10V transducer at the minimum and maximum range of the sensor. You can also type in the engineering units at Tab5. Finally…

Thank you for response.
I have another question.It seems that my controller converts resistance to temperature and in the table you sent, I don’t see how resistance can be converted to temperature. There is a uniform option to choose between temperature sensors.
I connected simple 10K sensor and I can read the temperature.

I am not fully following the question but the basic idea is there’s several built in ranges for 10k thermistors, type 2 and type3.

If you have a custom sensor with a different resistance curve you’ll have to build a table of resistance / voltages and temperatures which you can do with some simple voltage divider math. I’ll dig out a spreadsheet if that’s where you’re headed.
