Custom analog inputs

#1

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, fill in the signal type in the inputs table at Tab6.

Update: May 2020, added a parameter at Tab7 to let you edit the signal type directly from this dialog.

T3000 Custom Tables for Transducers with Negative Values

I tried to set up a custom table for building pressure.
0 - 10 Volt, bidirectional, Range -0.1 to 0.1
Is the range too low? Doesn’t seem to like decimal places or minus signs.
Thanks,
Bret

Good point, typical low pressure range for a building static pressure sensor. We’ll make the math work for the typical +/- 0.1 in WC type ranges.

Thanks much! It would also be wonderful if we could have three or more decimal places so there is really good resolution. :slight_smile:

Has there been any movement on this? I tried setting up a sensor for building pressure using a -.25 in. W.C. to .25 in W.C. transducer, but didnt seem to have the resolution. As far as I see I will need to use some math functions to work with the low value then transfer it back to actual value for the display.
