Input modules digitize strain gauge signals
Compensation in the measurement system eliminates absolute uncertainty in the measurement circuit.
B&R Automation has added two analogue input modules to its X20 I/O series that digitize signals from strain gauges to cut equipment costs and control cabinet space.
The X20AIA744 and X20AIB744 work with 4-wire strain gauge load cells, and compensation in the measurement system eliminates absolute uncertainty in the measurement circuit, such as component tolerances, effective bridge voltage or zero offset.
Both modules have 24-bit converter resolution.
B&R is a developer of automation and motion control technologies based in Atlanta.
