Capacitive level controls are widely used where it is necessary to control the level of substances both solid and liquid which may not be conductive. They are particularly used in silos for cereals, foodstuffs and the food industry in general. 
They are also used in the transport, dosing, stocking and handling of plastic materials, in foundries and cement factories.
The field of use is vast and is practically anywhere where it is necessary to control the level inside tanks which contain many types of different  material. They are supplied as a probe with aluminum housing and electrode rod or steel wire rope of various lengths teflon-coated, in addition to the range of capacitive sensors with rapid or delayed switching, with M18 and M30 threaded cylindrical housing with fixing nuts. 
A plastic protection housing suitable for food applications is available for some of our M30 sensors. We also manufacture high temperature M18 and M30 sensors ranging from -200°C to +250°C, these work combined with ALSC model amplifier which is supplied separately. To view the protection housing for capacitive and the high temperature capacitive sensors, pls. select these in the 'PRODUCTS INDEX' - 'LEVEL CONTROLS' section.
