Application description

The Precont® S70 is used in all fields of proceeding and process technique.

The excellent characteristics like pressure strength, high chemical resistance, corrosion protection and insensitivity against temperature shocks allows the use in the hardest applications for the measurement of gases, steams and liquids.

The process pressure is applied to the metallic membrane of the diaphragm seal and is transferred by vegetabe oil to the behind placed ceramic or metallic membrane of the respective measurement sensor. By this an essential extension of the permitted process temperature range up to -40...+370°C is achieved.
