Products Description
Product Definition
The Nexisense FST800-501 pressure transmitter is a high-performance sensor used for measuring and controlling the pressure of gases or liquids. It is widely applied in air conditioning and refrigeration equipment, providing accurate pressure data to ensure efficient operation.
Principle
The FST800-501 pressure transmitter utilizes advanced glass micro-melting technology, sintered at 500°C, employing the resistance strain principle to convert pressure signals into electrical signals. The internal sensor element can real-time sense pressure changes and uses digital signal processing technology for temperature compensation, ensuring high precision output across a wide temperature range.
Structure Analysis
The structure design of the FST800-501 adopts an integrated elastomer design, eliminating the common "O" rings and welding points found in traditional products, thereby removing the risk of leakage. Its pressure interface and sensor body are integrated, enhancing the device's corrosion resistance and durability.
