Requirements for level monitoringWherever plastic granulates are conveyed and processedcapacitive proximity switches are used to monitor levels inpipes and in silos or through sight glasses in loaders oninjection moulding machines. The sensor must reliablydetect a wide range of plastics in spite of differences inthe material, residual moisture and temperature. More-over, the grain size and surface characteristics of the basicsubstances vary considerably.
Application sensor for the plastic industryThe new M30 capacitive level switch was specially devel-oped to meet the requirements mentioned above. Thanksto the intelligent microprocessor technology even pre-dried granulates can be reliably detected. Optimum sensi-tivity adjustment to suit the medium is made automatical-ly by the press of a pushbutton. The front face of thesensor is rated for temperatures up to 110 °C and can bemounted in direct contact with the sight glass. The time-consuming setting of an air gap is no longer necessary.Due to its mechanical structure the sensor is speciallyimmune to the electrostatic discharges which occur when-ever plastics are conveyed.The user has the choice between DC and AC units. Theuniversal switching output can be programmed to be ei-ther NC or NO. Two highly visible LEDs clearly indicate thelevel from distance.
