Liquid Level Sensor

Liquid Level Sensor

Product Description​

The Liquid Level Sensor measures the height of water or other liquid and converts it to the voltage signal. It works with a data logger or other devices that have analog voltage input ports.

The Liquid Level Sensor has a built-in silicon piezoresistive core that features high sensitivity. The internal chip converts the millivolt signal into a standard voltage signal, which can be connected to a computer, a control instrument, or a PLC.

It's small-size and lightweight, easy to install. With a sealed stainless steel probe, it can work in water, oil, and mild-corrosive environments. The sensor has high anti-vibration and anti-impact performance. It can be widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC, and other applications.
