Non-contact Capacitive Liquid Level Switch Module - LLS-MCP1081-65-26

The non-contact capacitive liquid level switch module - LLS-MCP1081-65-26 utilizes the high dielectric constant characteristics of water to construct capacitive electrodes that penetrate the water tank to measure liquid level changes. The module is based on the independently developed ten-channel multi-mode broadband digital capacitive processor chip MCP1081, integrating capacitive measurement excitation, acquisition, microprocessor algorithms, temperature compensation, interface communication, and other functions. It has high sensitivity to liquids inside non-metallic containers, especially suitable for strong penetration scenarios where liquid level needs to be measured through the device housing, water tank shell, andair gaps.

The unique capacitive sensing electrode design, acquisition circuit design, and software algorithms can effectively overcome technical challenges such as thick container walls, liquid wall adhesion, scale, water quality variations, and EMC electromagnetic interference.
