Monosilicon Pressure Sensor

LEEG, a subsidiary of MICROSENSOR, is a leading manufacturer of hygienic transmitters in China's food and pharmaceutical industries. SPH19S is a piezoresistive pressure sensor with isolated construction and precise compensation. It uses high stable monosilicon sensor die. Stainless steel 316L housing with diameter Ф19mm. Wider temperature compensation and zero correction are calibrated by laser trimming techniques. The measured pressure is transmitted onto the silicon die through 316L diaphragm and inner sealed silicon oil, to transform the pressure to the electric signal. The sensor die doesn't contact the measuring medium directly, forming an isolated structure, suitable for various liquid media. Discover more pressure sensor models and types of Micro Sensor.
