The 2852-FCM 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. Variations in foam levels will result in a proportional output.
The 2852-FCM sensing probe monitors the capacitance field around the probe within a shield, tank or pipe. As the dielectric characteristics of a fluid or solid change, the resulting capacitance change is monitored and configured into a useable signal for process control and recording. A display is available in user configured engineering units.
Product dielectric changes in your application may not be strictly linear. Arjay has designed a 5-point calibration into the controller to enhance accuracy over an extended measurement range. The 2852-FCM is ideal for general monitoring and trending of process conditions.
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.
