Rockwell Automation 937CU-AISTR-DC1 Strain Gauge Converter Installation Instructions - Manual (Page 43)

Example
The weight of a
truck load is to be calculated. The empty weight of the truck can be between 7.5 t
and 15
t, the load to be measured can be up to 20 t. To prevent an overloading of the truck an
alarm is to be triggered at a weight above 20.5 t.
The truck rests on 4 weighing cells which have been connected in parallel at the input of the Strain
Gauge Converter. Each weighing cell has the following data:
•
Supply voltage 5 V
• Sensitivity 2 mV/V
• Maximum load: 15 t
• Internal resistance: 350
Ω
The mass of the truck weighing scales is 10 t.
Unit
The weight is to be displayed in the unit tons. In the menu Unit kg must be set. If the weight reaches
1000 kg the device automatically switches to t.
