Capacitive level sensors

The principle of the capacitive level sensor is that a sensor and vessel form an electrical capacitor whose electrical capacitance value depends directly on the height of the product in the tank. Capacitive sensors are particularly heavy duty and can withstand very high temperatures and pressures. They are easy to install and remain reliable, even with viscous or highly adhesive products. They can be used with liquids, granular products or powders. Unlike ultrasonic...
