Fluid`s process parameter e.g. conductivity, measuring sensor device, has nozzles and exhaust openings arranged together with axial displacement, where two nozzles are designed as nozzles flowing against sensor with tangential angle

摘要

The device has a sensor body (1) connected to a process container, and a tube-like sensor holder (3) movable between calibrating and measuring positions in a cylindrical guide channel (2) of the body. A measuring sensor (7) is held in the holder, where a calibrating chamber (13) is formed between the holder and the channel. Nozzles (18) and exhaust openings (21) calibrate- and/or rinse fluid flow in the chamber. The openings and nozzles are arranged together with an axial displacement, where two nozzles are designed as the nozzles flowing against the sensor with a tangential angle.
