Needle probe for measuring conductivity in liquids or multiple phase mixtures

摘要

The needle probe is mounted press. tight in the wall of a vessel carrying the measurement medium. It consists of a wire electrode (1) within an insulating tube (2) and possibly with an additional carrier tube (3). The seal between the inner electrode and the insulating tube is mounted on the end of the needle probe outside the measurement medium. Where the additional carrier tube is used, the seal between it and the insulating tube is arranged in the region of the probe outside the measurement medium, and the carrier tube represents an additional press. tight safety encapsulation of the needle probe.
