Piezoresistive Silicon Pressure Sensor Chips

In 1961, Shenyang Academy of Instrumentation Science started to research and manufacture silicon piezoresistive wafers. With excellent technology and well educated employees, we become the market leader in China for piezoresistive die.

We establish our reputation for cost-effective and quality. The pressure dies have been employed in pressure transducers widely in the world.
