Sanqiaohui | Manufacturer in Liquid Level Sensors for Coffee Machines

Liquid level detection is essential for coffee machines to ensure proper functioning, maintain safety, and enhance user experience.

Non-contact capacitive liquid level switch sensors are an advanced solution for coffee machines.

Based on the principle that capacitance varies when a liquid's dielectric constant changes near the sensor.As the liquid level rises or falls, the change in capacitance is measured to determine the level.
Can detect a variety of liquids (water, milk, coffee, syrups) regardless of their transparency or opacity.

Can be mounted externally on plastic, glass, or non-metallic containers.
Capable of detecting small changes in liquid levels with millimeter-level accuracy.
Supports real-time level monitoring and precise control for automated coffee machines.
Eliminates the need to drill or penetrate the reservoir, reducing installation complexity.

Enables seamless integration into coffee machine designs for functions like refilling alerts, low-liquid warnings, or automatic shutoff.
Accurately detects different liquids in a single reservoir, supporting coffee machines with multi-functional capabilities like brewing, milk frothing, and syrup dispensing.

Detects when water levels are low, triggering a refill warning or disabling the brewing process to prevent damage.
Monitors milk levels for frothing systems, ensuring consistent output for lattes or cappuccinos.
Identifies when the drip tray is full, preventing overflow and maintaining cleanliness.
