Coat-Endure is an improvement over traditional principle of admittance. The ring type probe has alternating active and inactive regions,which help the controller to calculate the extent of coating on probe. In effect the device is able to identify the relative coating between sense and the shield by measuring their individual capacitances. As the coating immunity is controlled by the on board microcontroller, the extent of coating immunity can be set easily.
