Introduction

The diffused silicon pressure sensor series consists of pressure sensing cores encapsulated with high-precision diffused silicon pressure-sensitive chips and mature manufacturing processes. As the core components for manufacturing pressure sensors and pressure transmitters, these high-performance pressure-sensitive elements can be easily amplified and assembled into transmitters with standard signal outputs.

Our company accepts customised development tailored to clients’ specific requirements, including pressure sensors with an all-welded structure, wide temperature compensation, custom outlines, high reliability, strong shock resistance and vibration resistance. We deliver cost-effective and reliable solutions for all customers.
