The Laureate™ Weight Meter is more compact and less expensive than available alternatives. It provides a choice of two signal conditioner boards: the Laureate load cell signal conditioner board, which provides full-scale ranges of 20, 50, 100, 250 and 500 mV with 4- or 6-wire load cell hookup, and the Laureate DC signal conditioner board, which allows the meter to accept preconditioned signals such as 0-10 V or 4-20 mA. Options include setpoint control, analog output and digital communication boards.
