Loadcell converter



Product outline

LC240 is a low-drift loadcell converter designed for loadcells.
With a U300DC preamplifier with a proven track record in stability adopted for the head amplifier, it realizes low drift and low noise features.
The bridge excitation power supply can be adjusted to 6 different levels besides the large capacity that allows up to 4 loadcells to be driven in parallel. LC240 is capable of loadcell converter that is standard equipped with the calibration function and current output.
