High-reliability converters optimized for the humid and demanding industrial environments of Vietnam.
Industrial-grade field communicator interface for Vietnam oil refineries.
Stable long-distance transmission for distributed control systems.
4-20mA to GPRS transmission, ideal for remote environmental stations.
Seamless Modbus RTU integration for sophisticated PLC networks.
As Vietnam positions itself as a global manufacturing powerhouse under the "Industry 4.0" national strategy, the demand for robust industrial communication has surged. In the heart of Binh Duong's factories and the offshore platforms of Vung Tau, the HART (Highway Addressable Remote Transducer) protocol remains the most critical bridge between legacy 4-20mA analog systems and modern digital diagnostics.
Vietnam's rapid expansion in petrochemicals, water treatment, and food processing requires sensors that can "talk." Our HART modems allow Vietnamese engineers to extract secondary variables (temperature, valve position, device health) without replacing existing wiring.
With strategic manufacturing in China, we provide the fastest lead times to Ho Chi Minh City, Hai Phong, and Da Nang, ensuring that infrastructure projects meet their critical deadlines without international shipping bottlenecks.
Our products are engineered to withstand the high humidity and salinity of Vietnam’s coastal industrial zones, featuring enhanced EMI shielding and tropicalized PCB coatings.
Established in 2007, Jiaxing Songmao Electronics Co., Ltd. has evolved into a global authority in protocol conversion. We don't just manufacture hardware; we deliver "Information Gain." By unlocking the digital data hidden in analog loops, we empower Vietnamese enterprises to transition from reactive maintenance to Predictive Asset Management.
For procurement managers in Vietnam’s EVN (Electricity Vietnam) or PetroVietnam, selecting a HART modem supplier involves more than just price. It involves understanding the Technical Roadmap of industrial communication.
Our SM100-TCP modules act as high-speed gateways. In a typical Vietnamese wastewater plant, multiple HART-enabled flow meters can be aggregated and converted into Modbus TCP/IP. This allows real-time data to be fed directly into SCADA systems or cloud-based monitoring dashboards via standard Ethernet infrastructure.
Traditional suppliers only provide the primary variable. Songmao’s converters are designed to extract all four dynamic variables and the device status byte. This provides "Information Gain" that allows for identifying sensor fouling or valve friction before a breakdown occurs—a critical advantage for the 24/7 production lines in Bac Ninh’s electronics hubs.
Offshore rig safety monitoring with intrinsically safe HART modems.
Precise metering and remote transmission across Vietnamese pipelines.
Pollution monitoring in accordance with Vietnam's Ministry of Natural Resources.
Comprehensive solutions for every interface: USB, RS485, RS232, and Ethernet.
The future of HART in Vietnam is evolving toward WirelessHART and Ethernet-APL (Advanced Physical Layer). Songmao is currently developing hybrid gateways that will allow Vietnamese industries to integrate high-speed Ethernet with the intrinsic safety of the HART loop.
As sustainability becomes a priority for Vietnam’s "Net Zero 2050" goal, our data collectors play a vital role. By optimizing process control through better data, plants can reduce energy consumption by up to 15%. We provide full local support through our regional distribution partners, ensuring that technical documentation is accessible and technical support is available in relevant time zones.
Our converters feature wide-range voltage input protection and 1.5KV galvanic isolation to protect sensitive field equipment from voltage spikes common in rural industrial zones.
Yes, our HART modems use standard Bell 202 FSK technology, making them 100% compatible with major software like AMS Suite, Pactware, and FieldCare used across Vietnam.
With an MTBF (Mean Time Between Failures) of over 50,000 hours, our products are built for longevity. We use anti-corrosion materials specifically tested for tropical climates.
