T30 Liquid Level Optical Sensor with Amplifier (Analog & Digital Output)

T30 Liquid Level Optical Sensor with Amplifier (Analog & Digital Output)

The T30 Liquid Level Optical Sensor is a high-precision infrared liquid level detector designed for reliable and accurate fluid monitoring. Operating on the infrared optical principle, it detects liquid levels by transmitting and receiving optical signals through the fluid, converting them into precise electrical signals for level measurement and control.

Unlike traditional float-type sensors, the T30 sensor has no mechanical moving parts, resulting in zero friction, long lifespan, and superior accuracy (±0.5mm). Its compact and waterproof design makes it suitable for a wide range of applications including water dispensers, purifiers, humidifiers, and industrial liquid level monitoring systems.

Key Features

• Infrared Optical Detection: Ensures accurate and reliable liquid level measurement.

Design & Usage Notes

• Always use an A/D port for accurate analog readings rather than direct high/low detection.

• Implement data sampling and averaging to ensure stable and reliable measurements.

• Keep the sensor’s tail section dry to prevent internal condensation.

• Use waterproof protection in high-moisture or steam environments.
