Features
1. No mechanical moving components and with high reliability.
2. Small in size and low in cost.
3. High liquid level control precision and can be installed from any direction.
4. Satisfying the requirements in Safety Standards.
5. The sensor itself satisfies RoHS requirements.
6. Waterproofing standard IP64.
7. Accuracy is between ±0.5mm.
8.The sensor can be installed on the top, bottom, side and incection.
How does the sensor work?The optical liquid level switch uses an infra-red LED and totransistor accurately positioned at the base of the switches tip. When the tip is in air, the infra-red light from an LED is internally reflected round the tip and back to a totransistor. When the tip of the switch is immersed in liquid, the infra-red light escapes from the tip causing a change in the amount of light at the totransistor which makes the output change state.
Can be used in:Water dispenser, water heater, humidifier, medical devices or equipment, electrical appliances and equipment’s etc. requiring liquid-level control.
