Leading hardware for seamless communication between field instruments and control systems.
In the era of Industry 4.0, the "HART (Highway Addressable Remote Transducer)" protocol remains the backbone of process automation. As industrial plants globally transition from purely analog 4-20mA signals to digital diagnostics, the demand for a reliable USB HART Interface has surged. Global enterprises in the USA, Germany, and Southeast Asia are prioritizing procurement of interfaces that offer galvanic isolation, high-speed data throughput, and multi-OS compatibility.
The primary driver for this demand is the need for "Field Intelligence." Maintenance engineers require portable, plug-and-play tools to configure, calibrate, and troubleshoot smart transmitters directly from a laptop. A high-quality China-manufactured USB HART Modem provides an essential cost-to-performance ratio, allowing large-scale deployment across vast refinery and water treatment facilities without compromising technical integrity.
Our solutions target the critical pain point of "Legacy Modernization." Many plants operate with sensors installed decades ago. By integrating our HART to Modbus or HART to Ethernet gateways, enterprises can extract "stranded data" from these sensors—such as device temperature, secondary variables, and valve health—without replacing the entire wiring infrastructure.
Jiaxing Songmao Electronics Co., Ltd. was established in 2007. For over 18 years, we have been driven by technological innovation, deeply engaged in the field of industrial automation. We are a high-tech enterprise integrating R&D, production, and sales, specializing in HART protocol communication products and data collectors.
Our commitment to quality and technical support has made us a leading China USB HART Interface Supplier, serving over 40 countries with precision-engineered hardware that survives the harshest industrial environments.
The roadmap for HART communication is evolving towards HART-IP and WirelessHART integration. At Songmao, our R&D focus is on the miniaturization of interface hardware while increasing the robust isolation levels (up to 1500VDC) to protect PC equipment from ground loops and industrial surges.
Transitioning from USB-A to USB-C and integrating Bluetooth low-energy for wireless field configuration.
Developing firmware that can pre-analyze HART burst mode data to predict instrument failure before it happens.
Expanding our converters to support multi-protocol environments including Profibus, Modbus TCP, and MQTT for Cloud-IoT integration.
Songmao's communication interfaces are deployed in critical infrastructure worldwide.
Real-time pressure and flow monitoring in hazardous areas via HART data collectors.
Optimizing heat exchange efficiency through precise MODBUS-based sensor networks.
Ensuring water quality with 8-channel HART data acquisition modules for remote telemetry.
As a global USB HART Interface Factory, we understand that "Reliability" is not just a word—it is a certification. Our products comply with international standards including CE, RoHS, and FCC. We provide localized technical documentation in English and offer direct engineering support for custom protocol mapping (e.g., Modbus RTU to HART 7.0).
For international distributors, we provide OEM/ODM services, ensuring that the hardware meets the specific voltage and mounting requirements (DIN Rail or Panel Mount) of your region.
Expert insights into HART interface selection and implementation.
A: A USB HART interface allows you to use powerful PC-based FDT/DTM software (like Pactware or Rosemount Radar Master), providing a much larger interface for complex calibration, waveform analysis, and data logging that handheld units cannot match.
A: Yes, our SM100 series supports HART multi-drop networking, allowing you to connect up to 15 devices on a single loop for data acquisition via Modbus or Ethernet.
A: Absolutely. Our professional-grade USB HART modems feature 1500VDC galvanic isolation to protect your laptop's USB port from field-side electrical surges and noise.
A: Yes, by using our HART to Modbus TCP or HART to Ethernet modules (SM100-TCP), the field data is converted into standard industrial protocols that any modern SCADA or PLC can read.
A: We provide drivers for Windows 7, 8, 10, and 11, and our hardware is compatible with major automation software platforms including Emerson, ABB, and Siemens software suites.
