Relative pressure transmitter YD38

thin-filmpiezoresistive4-20 mA

YUNYI High-temperature melt pressure transmitters are specialized pressure measurement instruments designed for extreme high-temperature conditions. Utilizing high-temperature sputtered thin-film technology or high-temperature piezoresistive technology, they directly contact high-temperature molten media to perform precise pressure measurements. Their unique heat dissipation and isolation design ensures high accuracy of ±0.3% FS even in high-temperature environments (up to 450°C), completely resolving pressure monitoring challenges for high-temperature, high-viscosity media in industries such as plastic extrusion and chemical fiber spinning. These transmitters are indispensable key monitoring equipment in high-temperature melt processing workflows. Product Advantages 1. Extreme High-Temperature Resistance: Features a specialized heat dissipation structure that directly contacts 450°C molten material without requiring cooling devices, reducing system complexity. 2. High-Precision Measurement: Utilizes high-temperature sputtered thin-film technology to maintain ±0.3% FS accuracy in high-temperature environments, ensuring process stability. 3. Multiple Wetted Materials: Offers various diaphragm materials including 15Mo3, 17-4PH, and Hastelloy to accommodate different corrosive media. 4. Strong Interference Resistance: Fully welded sealed construction with IP65 protection rating, resistant to vibration and impact for harsh industrial environments 5. Simple Installation & Maintenance: Standard M20×1.5 or 1/2-20UNF interfaces for direct mounting without additional adapters
