Coat-Endure is a microcontroller based compact coat-immune admittance level limit switch. It is suitable for sticky solids and pastes. The device has been designed for compact silos and packaging machines where material has tendency to stick on the probe. It is an improvement over traditional principle of admittance. The 3-element 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 the 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.
