Introduction
BS12D piezoresistive differential pressure transducer is OEM pressure transducer applied in differential pressure measuring, typically of gases, vapor or liquids. Two high-sensitivity piezoresistive silicon pressure chips are employed inside the transducer.
The stainless steel housing protects the chips against ambient influences. The measured differential pressure is transmitted onto the die through the diaphragm and filling silicon oil, finally it is converted into an electrical signal. Widely used for industrial process control and differential pressure measure fields, etc.
