In high-temperature melt processing applications such as plastic extrusion, chemical fiber spinning, and rubber processing, the accuracy, safety, and environmental sustainability of pressure measurement directly affect product quality, production efficiency, and regulatory compliance. Traditional mercury-filled melt pressure transmitters pose significant safety risks due to their toxic mercury medium and fail to meet modern environmental requirements.
To address these challenges, ZHYQ has introduced its Mercury-Free High-Temperature Melt Pressure Transmitter, featuring three core advantages: eco-friendly design, ultra-stable temperature performance, and precise measurement & control. It provides an ideal domestic alternative for high-temperature melt pressure measurement and supports the transition toward greener and more sustainable industrial manufacturing.
High-temperature melt applications (up to 400°C) place extremely demanding requirements on temperature drift control, measurement accuracy, and long-term stability. Conventional transmitters often suffer from data drift and signal fluctuations under such conditions. ZHYQ’s mercury-free melt pressure transmitter delivers comprehensive performance upgrades:
1. Ultra-Wide Temperature Resistance & Ultra-Low Thermal Drift
The sensing diaphragm is manufactured from 17-4PH coated stainless steel, capable of withstanding temperatures up to 400°C, ensuring reliable performance in extreme environments.
2. High Accuracy & Fast Response
Offering a total accuracy of ±0.25% FS to ±0.5% FS and a response time of ≤5 ms, the transmitter can capture even the slightest melt pressure fluctuations in real time. This provides precise data support for closed-loop pressure control in extruders and spinning equipment.
3. Highly Stable & Durable Construction
Featuring an all-stainless-steel integrated housing, the transmitter provides excellent vibration resistance and is suitable for high-viscosity melt media containing fine particles. An internal 80% calibration signal is built in, supporting both zero-point and span adjustments.
4. Flexible Pressure Ranges & Output Signals
Pressure ranges are available from 0–3.5 MPa to 0–300 MPa, with support for standard outputs including 4–20 mA, 0–10 V, and 0–5 V. The transmitter can be directly integrated into PLC control systems and is compatible with mainstream industrial instruments worldwide.
Additional Features
1. Multiple Process Connection Options
Standard process connections include 1/2″-20UNF, M14×1.5, and M18×1.5, while customized non-standard connections are available upon request.
2. Simultaneous Pressure and Temperature Measurement
Selected models support simultaneous pressure and temperature measurement at the same sensing point, allowing one device to perform dual functions, simplifying equipment layouts and reducing procurement costs.
Thanks to its comprehensive advantages in environmental protection, accuracy, and stability, the ZHYQ Mercury-Free High-Temperature Melt Pressure Transmitter has been widely adopted in industries including:
- Plastic extrusion
- Chemical fiber spinning
- Rubber processing
- Polyester production
- Food processing
- Pharmaceutical manufacturing
It has become a preferred solution for high-temperature melt pressure measurement applications.
Founded in 1999, ZHYQ is a high-tech enterprise integrating R&D, manufacturing, and sales. The company invests approximately 12% of its annual revenue into research and development and holds nearly 90 national patents. ZHYQ has obtained multiple certifications, including ISO and CE, demonstrating its commitment to quality and innovation.
As one of the company’s flagship self-developed products, the High-Temperature Melt Pressure Transmitter offers performance comparable to imported alternatives from brands such as Dynisco and Gefran, while providing a more competitive cost-performance ratio. In addition, ZHYQ offers comprehensive technical support and localized after-sales service, helping customers overcome challenges associated with long import lead times and high maintenance costs.
Green development is an inevitable direction for industrial transformation, while precise measurement remains the foundation of intelligent manufacturing. With its key advantages of mercury-free environmental protection, high-temperature accuracy, long-term stability, and excellent cost-effectiveness, the ZHYQ Mercury-Free High-Temperature Melt Pressure Transmitter enables manufacturers to achieve safer, greener, and more efficient process control in high-temperature melt production environments.
Looking ahead, ZHYQ will continue to advance sensor and measurement technologies through innovation-driven product development, delivering high-quality, domestically manufactured measurement solutions for a wide range of industrial applications and contributing to the high-quality development of China’s green intelligent manufacturing sector.
