The LCA1 load cell amplifier is designed to provide highly precise amplification of load cell signal for use with dyno controllers. Gain is adjusted to allow 20% load cell overload without clipping with 2mV/V load cell and DC1 controller. The amplifier is enclosed in a standard DIN rail enclosure.
Amplifier with custom gain is available upon request. For example, for 3mV/V load cell.
