DQ-309H Digital Transmitter – Next-Gen Multi-Channel Weighing & Force Measurement
DQ-309H Digital Transmitter – Next-Gen Multi-Channel Weighing & Force Measurement
Product Description:
Upgrade your industrial weighing system with the DQ-309H digital transmitter. Engineered for multi-channel force and weight measurement, this compact device supports up to 6 independent ADC channels and works seamlessly with analog resistive strain gauge sensors (sensitivity: -3mV/V to 3mV/V). Featuring high-speed Ethernet, simultaneous RS232/RS485 ports, and MODBUS-RTU/TCP protocols, the DQ-309H delivers fast, stable, and noise-resistant data transmission. The 0.96-inch OLED display and intuitive membrane keys make setup and monitoring effortless — all in a space-saving DIN35mm rail-mount design.
