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 ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

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 ...

AutomationDirect has added the Flowline EchoTouch, EchoSpan, and EchoSwitch lines of ultrasonic liquid level sensors and transmitters, as well as the PodView digital level indicator to their product ...

As an important physical parameter that characterizes the state and properties of an object, temperature plays a very important role in our production life. Flexible thin-film temperature sensors, ...
