ELX3351 - Introduction
Fig. 3: 1-channel analog input terminal for strain gauge, 16 bit, Ex i
The analog ELX3351 input terminal enables direct connection of a resistor bridge or load cell from
hazardous areas, Zone 0/20 and 1/21. The terminal can be connected in 4- or 6-wire technology. The ratio
between the bridge voltage U
D
and the supply voltage U
R
is determined in 24-bit resolution, and the load
value is calculated as a process value. Apart from automatic self-calibration (can be deactivated), additional
functions such as Tara and Freeze as well as dynamic filters are integrated.
