Bipolar fluid conductivity sensor for detecting conductivity of fluid in e.g. process container in food sector, has seal provided between insulator and internal electrode to seal threaded connection, where seal is removable using electrode

摘要

The sensor (1) has an internal electrode (8) and an external electrode (9) immersed into process fluid (F), where the internal electrode is attached to a housing (5), and the external electrode is arranged around the internal electrode at a radial distance. An insulator (13) is arranged between the electrodes, and a detachable threaded connection (A) is provided between the internal electrode and an electrode holder (3). A seal (19) is provided between the insulator and the internal electrode for sealing the connection, where the seal is removable using the screwed internal electrode.
