Coat-Endure – for Sticky Media
Published on : Monday 30-11--0001
Coat-Endure is a microcontroller based compact coat-immune admittance level 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.
Mounting Arrangement for Coat-Endure
The instrument when calibrated at a single point i.e. in air, can be used with a variety of materials for level detection. When material reaches the switching point, the instrument detects the presence of the material and changes the outputs accordingly. The relay contacts / PNP output / current output can be used for maintaining the level of the material within the desired range in the tank.
Principle
Coat-Endure 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.
