T3000 Custom Tables for Transducers with Negative Values

[maurice]

There is a section on configuring custom tables for transducers and so on, I have included the link further down, however there are a lot of folks setting up positive pressure rooms for the Covid 19 response so I’ll add this example showing a negative to positive pressure range typical of clean room applications.

Click at Tab1 to bring up the inputs grid and again at Tab2 to bring up the various ranges and again click at Tab3 to bring up the custom analog ranges. At Tab4 you can specify the engineering units, inWC in this example but you can use Pascals or whatever units you like there. At Tab5 we specify two data points since we’re working with a linear transducer we only need to specify the min and max values of the table. Over to the right you type in the negative value for the pressure at 4ma transducer signal and also at the 20ma signal level. Finally at Tab6 you specify the 4-20ma signal type, you can pick from 0-5V, 0-10V and so on depending on your transducer. Click apply and you’re done.

Here’s the link to another example of setting up custom ranges:

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…
