FOAM CONTROL - WHAT IS IMA SENSING?

The unique IMA (Intelligent Multi-Action) sensing facility is the backbone of many of Hycontrol’s foam monitoring products. The patented IMA SensingĀ® technology enables Hycontrol sensors to discriminate between the residual deposits of foam and product that build up on the sensor itself, and the foam being created in the process.

Effectively the foam sensor ignores the inevitable fouling that will accrue during normal operation while continuing to monitor the foam. No matter how heavily the sensor is coated or how dense and sticky the layer, its unique construction enables it to keep measuring foam throughout the process cycle.

The diagram on the right shows a Hycontrol foam sensor coated in a sticky build-up of foam and product. The measuring current which is shown in red on the graphic continues to flow only through the foam. The blue line represents the leakage current driven by the guard electrode. This enables the sensor to function as the leakage is measured separately and not as part of the foam signal.

Often it is not possible to prevent material build-up but our IMA technology enables the sensor to function reliably despite extensive coating or fouling. To see a short video demonstration of IMA sensing technology at work please click below:
