2882-FCS Foam Control Switch

2882-FCS Foam Control Switch

Overview

The 2882-FCS Foam Control Switch provides reliable monitoring of foaming conditions in process applications. The 2882-FCS sensing probe continuously monitors the capacitance of the inserted probe. As the foam intrudes into the normal air or vapour space of the probe, the capacitance changes and an alarm output is provided.

It’s unique processor and oscillation frequency combination make the 2882-FCS ideal for foam suppression applications. These include oil/water knock-out and treater trains, bulk separators, coalescing chambers, pre-compressor manifolds, wastewater sumps and ponds.
