These I/O modules enable you to integrate a loadcell or strain-gauge in your control application.
Note that there are two methods of calculating weight according to user units: via Formula, or using a UDFB.
A sample application showing both methods may be found in the UniLogic Example applications, which may be downloaded here in the Unitronics web site.
Refer to the Unitronics module's data sheet for details regarding calibration, zeroing, etc. |
When you include a URB Loadcell/Strain-gauge I/O module in your program, UniLogic creates a struct containing the parameters you need to calculate weight.
You can use the formula ((A * 15.0 * C )/(D * B))*E configured as shown below.
Parameters A and B relate to the Unitronics I/O module's inputs.
Parameters C and D relate to the specifications of the Loadcell /Strain-gauge device you connect to the Unitronics' I/O module.
Parameter E, Scale Factor, can be used to fine tune measured results if required by using known weight, and according to calculated result, calculating the required offset percentage.
