3-channel load cell signal transmitter DA03 utilizes a 24-bit Sigma-Delta ADC with 10Hz / 40Hz / 640Hz / 1280Hz optional A/D conversion rate. Analog-to-digital signal conditioner DA03 offers RS485 and RS232 two interfaces supporting Modbus RTU and ASCII protocol. The wide input range from 0.5mV/V to 5mV/V makes it compatible with most load cell transducers produced based on strain gauge technology. Amplifier DA03 can work with up to three load cells, each load cell can be calibrated separately through debugger DA-M which can also be used for parameter setting. The host computer can read the measurement values of the three channels individually or the summed value of the three channels. Digital converter DA03 offers an ideal signal processing solution for 3-axis load cells and hopper weighing scales with 3 supporting legs.
