AQ Elteknik AB FCS22-50 Air Sensor Stainless Steel

The AQ Elteknik AB FCS22-50 Air Sensor is an inline sensor with a 316L stainless steel wetted part (1.4404) for corrosion resistance in demanding environments. Model Number FCS22-50 features an inner diameter of 22 mm, an outer diameter of 64 mm, and an overall length of 100 mm, with a 50 mm tube connection (TC 50 mm) to match standard process piping. It ships with a fixed 5 m electrical cable for straightforward mounting and wiring. This sensor is part of AQ Elteknik’s Air Sensor family and is described in official manuals alongside related bore and connection configurations. The 316L wetted surface provides durability in liquids and mildly corrosive media, while the 64 mm outer envelope supports installation in constrained spaces. Designed for use with AQ Elteknik ultrasound-based air-detection systems, it enables inline monitoring of air presence or entrained gas in liquids within industrial processes. The combination of a 22 mm ID bore, 50 mm TC, and a fixed 5 m cable makes the FCS22-50 a precise, reliable option for piping networks that require robust, stainless-steel air sensing.
