Product Details
Key Features & Advantages
Robust Construction: Machined from a solid piece of 17-4PH stainless steel with a fully welded, all-metal sealed design, eliminating O-rings and organic materials exposed to pressure media. This ensures leak-proof performance, excellent corrosion resistance, and long-term reliability in harsh environments, including extreme temperature fluctuations, high humidity, condensation, and icing.
Wide Compatibility: Suitable for all non-corrosive refrigerants, ammonia, lubricating oil, and water, making it ideal for centrifugal/screw chillers, heat pumps, cold storage, and industrial refrigeration equipment.
Superior Protection: Built-in surge protection, overvoltage protection for both positive and reverse polarity, and environmental sealing for electronics, ensuring stable operation even in unstable power conditions and industrial environments.
Easy Installation: Equipped with a standard 1/4" SAE 45° flare internal thread port with Schrader valve depressor, paired with a 2-meter shielded cable for direct mounting, simplifying installation and replacement in existing systems.
Compliance & Certification: Exceeds the latest CE/UL industrial standards, with digital temperature compensation ensuring high accuracy across a wide operating temperature range, guaranteeing consistent performance and system safety.
