The SmartFoam IMA sensor from Hycontrol, UK is designed to detect and control a wide range of light to dense foams with a single foul-resistant probe. The Suresense+ Controller protects from overflow and blockage, prevents pollution and enables dosing of anti foam agents to reduce cost.
The SmartFoam IMA sensor and Suresence+ Control Panel is used in Food Processing, Carbonated Beverages, Brewing, Paper Manufacture, Waste Water & Effluent Treatment and Activated Sludge Tanks.
- protection from foam overflow and blockage
- reliable, robust and immune to fouling (see graphic)
- easy to clean and fully weather-proof enclosure
- saving on anti-foam chemicals in pH dosing adjustment
- 10 light to dense (watery) foam sensitivity levels
- stainless steel construction with PVDF insulator, customized sensor insertion length
How it works
The new SmartFoam sensor passes a small alternating current through the foam into the liquid below which responds to the density of the foam. When the measurement passes a pre-set level the sensor then recognises that foam is present.
To avoid false alarms the unique IMA Sensing® technology is able to distinguish the presence of active foam from the build-up of a sticky ‘fouling’ layer on the surface of the sensor by a guard electrode which isolates and compensates for the effect of any fouling layers.
The Sensor has a built-in time delay which can be set between 1 and 4 seconds to reject splashing and other spurious events.
The SmartFoam has a volt-free output which can be connected directly to a PLC or can be used to switch a low voltage signal e.g. 24VDC. The two small indicators in the sensor head show power and foam detection.
