There have EL3356-0010 Beckhoff 1-channel analog input quantifying bridge & full bridge 24 bit high-precision or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is resolute simultaneously in the input circuit and the final load value is calculated as a process value on the substructure of the settings in the terminal. With automatic self-calibration (can be deactivated), dynamic filters and distributed clock support, the terminal with quantifying cycles of 100 µs can be utilized for expeditious and precise monitoring of torque or vibration sensors.
