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