Gravity: Non-Contact Digital Water/Liquid Level Sensor

This is a non-contact water / liquid level sensor. It utilizes advanced signal processing technology by using a powerful chip (XKC-Y25-T12V) with high-speed operation capacity to achieve non-contact liquid level detection.
No contact with liquid makes the module suitable for hazardous applications such as detecting toxic substances, strong acid, strong alkali, and all kinds of liquid in an airtight container under high pressure.
There are no special requirements for the liquid or container and this liquid sensor is easy to use and easy to install.
The liquid level sensor is equipped with an interface adapter that makes it compatible with DFRobot "Gravity" interface. Four levels of sensitivity can be configured by pressing the SET button.

Taidacent Non Contact Liquid Level Sensor Contactless Water Level Sensor Externally Attached Pipe Water Float Switch NPN Output Capacitive

The intelligent non-contact liquid level sensor uses advanced signal processing technology and high-speed signal processing chip to break through the influence of the wall thickness of the container and realize the true non-contact detection of the liquid level in the closed container.
The liquid level sensor (probe) is installed above and below the outer wall of the container to be tested (the high and low positions of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect the production.
The liquid level of various toxic substances, strong acids, strong alkalis and various liquids in the high-pressure closed container can be detected.
The liquid to be tested is required to be electrically conductive, the contact surface is non-metal, and the pipe is easy to install and can be widely used.
NPN output: If there is induction, the output is low level; no induction, disconnected
