According to the application characteristics of different industries, PM430 sanitary pressure transmitter carefully select high-reliability silicon piezoresistance, ceramic capacitors, sapphire, sputtering thin film pressure sensors as the sensitive core. After temperature compensation, digital circuit correction and signal conditioning, the output standard Industrial applications and networking signals. The production process continues the company’s 20-year rigorous work style and meticulous process control spirit. Each type of product is carefully designed, component selection, process verification and curing, cyclic loading stress relief, aging, and environmental simulation testing. Only the product is stable and reliable.
With its excellent accuracy and reliability, PM430 series pressure transmitters are widely used in many types of pressure measurement users, especially in coal mines, oil fields, chemical industry, civil explosion, environmental protection, medicine, water affairs, shipping and other industries.
