EL3356-0010 | 1-channel precise load cell analysis (resistor bridge), 24 bit

The analog EL3356-0010 input terminal enables direct connection of a resistor bridge or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the terminal. With automatic self-calibration (can be deactivated), dynamic filters and distributed clock support, the terminal with measuring cycles of 100 µs can be used for fast and precise monitoring of torque or vibration sensors.
