Contact Multi-point Photoelectric Liquid Level Sensor

The new contact multi-point liquid level sensor is a contact liquid level measurement and control device designed using optical principles. The sensor can detect 4 liquid levels with a detection accuracy of up to ±1mm. The sensor has no mechanical parts and does not require additional debugging. It has high sensitivity, low power consumption, corrosion resistance, high pressure resistance, high temperature resistance, and stable chemical properties.

Note: Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.
