PTL704 anti-corrosion pressure transmitter

The corrosion-resistant pressure sensor adopts ceramic piezoresistive chips, high polymer high-density materials that are resistant to strong acids and strong alkalis, and corrosion-resistant cables. After soaking in 37% HCL hydrochloric acid for two years, there were no abnormal phenomena. It is mainly used for pressure measurement and control in industries such as chlorine gas for disinfection of tap water, chemical industry, battery equipment, etc. with strong corrosive media such as strong acids and strong alkalis, as well as food hygiene, medical and other industries.
