PTJ404 anti-corrosion pressure sensor/transmitter (high corrosiveness, strong acidic medium pressure measurement and control instrument)

Haojie Electronics anti-corrosion pressure sensors/transmitters have the following characteristics:

1: Adopting ceramic piezoresistive chips/corrosion-resistant cores

2: The shell is made of polyethylene terephthalate

3: Adopting independently developed interference circuits

4: High polymer high-density material with anti-corrosion cable

The anti-corrosion cable is made of ceramic piezoresistive chips and high-density polymer materials that are resistant to strong acids and alkalis. 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 with strong corrosiveness such as chlorine gas for water disinfection, chemical industry, battery equipment, as well as food hygiene, medical and other industries.
