Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technology has progressed to such an extent that refrigerators can now ...
Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...
Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...
The CAP-100 Series capacitive liquid-level sensors provide accurate level sensing through the walls of plastic, glass, and fiberglass bottles. The sensors are suitable for medical applications such as ...
Studies conducted in this development used three different light-emitting diode/photodiode sensors to measure Solvent Red 26 in kerosine and Solvent Red 164 in diesel at concentrations ranging 0-43 mg ...
Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
