The 2852-FCS provides reliable monitoring of foaming conditions in process applications. The sensing probe is tuned to the normal operating conditions of the gaseous or air phase in your process. The intrusion of foam around the probe will cause a capacitance change that is monitored by the remote controller. Two alarm setpoints with full differential are available for control and alarm functions. Typical applications include free water knock-out (FWKO) systems, gas phase separation, pre-compressor main-fold protection, and wastewater treatment facilities. The unique Arjay pulse module circuit makes this unit ideal for foam suppression, interface and control.
