An Industry White Paper on Connectivity, Efficiency, and Intelligence
Traditional 4-20mA signals only transmit a single process variable. A USB HART Communicator unlocks the secondary, tertiary, and quaternary variables stored within smart field devices. By utilizing the Bell 202 frequency shift keying (FSK) standard, our SM100 series modems provide the data depth required for modern predictive maintenance.
As industry moves toward HART 7.0 and Ethernet-APL, the role of the protocol converter is shifting. Our R&D roadmap focuses on bridging legacy HART loops with cloud-based MQTT and OPC-UA architectures, ensuring that a simple USB interface can act as the secure gateway for industrial asset management (PAM) systems.
Whether in Oil & Gas, Water Treatment, or Environmental Monitoring, the need for robust data acquisition is universal. We provide integrated solutions where HART modems work in tandem with GPRS/4G data collectors to provide a complete "field-to-screen" data pipeline, reducing operational expenditures by up to 30%.
SONGMAO Electronic co., Ltd. was established in 2007. Driven by technological innovation, we have deeply engaged in industrial automation for over 18 years. As a high-tech enterprise integrating R&D, production, and sales, we focus on the independent development of core HART protocol communication products.
Our commitment to quality has allowed us to establish a leading position in the industry, serving clients in over 40 countries. Our Jiaxing factory is at the forefront of the China Industry 4.0 movement, implementing smart manufacturing to ensure supply chain resilience.
