Working Principle
The SHY Series Differential Pressure Transmitter is designed to measure the pressure difference between two ends of a process system. It uses a high-precision monocrystalline silicon differential pressure sensor combined with temperature compensation technology to convert pressure difference into a stable electrical output signal.
The product adopts an overload protection diaphragm design and internal circuit surge protection design. During operation, the pressure from both sides acts on the sensing element, and the internal circuit converts the detected pressure difference into a standard signal output for transmission, display, and control. It can be used for accurate measurement of gauge pressure, differential pressure, flow, and liquid level in industrial processes.
