Product description Parameter Output current 12mA Working temperature -25~105℃ Custom processing Yes Material PC Measuring range unlimited Type Photoelectric level switch Measurement accuracy critical judgment Application Humidifiers, air-conditioning fans, steam and other electrical products that require water level control and protection Schematic diagram Feature 1. Compact structure and small size 2. High precision of liquid level control 3. High reliability and long life Size Advantage Compared with the existing float type liquid level switch: 1. The liquid level switch is small in size and compact in structure, so the installation space is small and the installation process is simple. However, the existing float type liquid level switch has large volume, loose structure, large installation space, and complicated design and installation. The float type liquid level switch is driven by the buoyancy of the liquid to move the float with the magnet up and down, so as to open and close the internal reed switch, so the float has a certain draft, so the minimum liquid level will be greatly limited. This level switch does not have this limitation. 2. The liquid level switch can be installed up, down, sideways and diagonally, while the existing float type liquid level switch can only be installed up and down. 3. The liquid level control accuracy of this liquid level switch is high, within ±0.5mm, while the existing float type liquid level switch has an accuracy of ±3.0mm or even higher. 4. There is no friction and mechanical moving parts, so the reliability is high. However, the existing float type liquid level switch floats are easy to jam and cause defects. 5. The head is smooth and easy to clean. 6. Built-in emitter diode and phototransistor, so it has a long life. 7. The live parts are completely isolated from the controlled liquid, and there are no safety hazards.
