Ziasiot Sensor pioneered China’s first mercury-free, eco-friendly high-temperature melt pressure transducer, which marking a significant technological breakthrough in the melt pressure industry.
A Safer Alternative for extrusion melt pressure applications
Traditional melt pressure transducers and thermometers have long relied on mercury (Hg) as a filling medium. However, mercury poses severe health and environmental risks due to its toxic vapor. While some manufacturers switched to sodium-potassium (NaK) alloy as an alternative, this solution carries flammability and explosion hazards in chemical, fiber, and polymer production systems.
Ziasiot’s R&D team spent over two years developing a patented, non-toxic liquid alloy filling medium that eliminates these risks. The innovation has obtained RoHS and CE certifications, ensuring compliance with international environmental and safety standards.
Key Advantages of Ziasiot’s Mercury Free Melt Pressure Transducer:
✔ Mercury & NaK-free – Safe for operators and the environment, PLC & SIL2 certified.
✔ High-temperature resistance – Up to 400°C
✔ AFT technology – Enhanced accuracy and durability
✔ Multiple diaphragm materials – Customizable for different industrial needs
✔ One-button zero calibration – Easy on-site adjustment
Remark: What Does SIL2 for melt pressure transducers Mean?
In high-temperature, high-pressure industrial environments (e.g., plastics extrusion or chemical processing), SIL2-certified melt pressure transducers provide:
Higher Safety and Reliability, Risk Reduction, Enhanced Diagnostics and Compliance with Industry Standards
Safety Integrity Level 2 (SIL2) is a critical benchmark defined by the IEC 61508 and IEC 61511 international standards, governing the performance and fault tolerance of safety-related systems. This classification applies to industrial sensors, including melt pressure transducers, ensuring they meet stringent reliability criteria for risk mitigation.
For extrusion melt pressure industries where sensor failure could lead to safety incidents or costly downtime, SIL2 certification is a key differentiator in selecting mission-critical components.
Industry Recognition & Market Impact
Leading companies such as Rongsheng Chemical Fiber Group, Hengyi Group, Hyosung Chemical Fiber, and Zijiang Group have already adopted Ziasiot’s mercury free melt pressure transducers. The company projects annual orders worth $20 million, aiming to rank among the top three global suppliers in this sector
