PM424 Barometric Pressure Transducer For High Temperature

According to the application characteristics of different industries, PM424 series barometric pressure transducer carefully select high-reliability silicon piezoresistance, ceramic capacitors, sapphire, sputtering film pressure sensors, etc. as sensitive cores. After temperature compensation, digital circuit correction and signal conditioning, the output is standard Industrial applications and networking signals. The production process continues the company’s 20-year rigorous work style and refined process control spirit. Each type of product has been carefully designed, component screening, process verification and curing, cyclic loading, stress relief, aging, environmental simulation testing and other processes to ensure every Only the product is stable and reliable.
