The water level switch sensor FS-IR02-PH2.0-NT uses the principle of total reflection in a prism. Reflection or penetration, is the basis of the level alarm output. When the sensor is surrounded by air, the angle of incidence is greater than the critical angle and thus total reflection occurs. Totally reflected light will be transmitted to the receiver. Conversely, when the sensor is surrounded by liquid, due to the refractive index of the liquid and the sensor tip material, almost all light will penetrate the front of the sensor. Using this principle, the optical liquid level switch design is based on light. The receiver can detect and determine a light reflected or penetrated state, and determines the circuit output.
1. Compact structure and small size
2. High liquid level control accuracy
3. High reliability and long life
4. Low price
Compared with the existing float type liquid level switch:
1. The liquid level switch is small in size and compact in structure, so the space required for installation is small and the installation process is simple. The existing float type liquid level switch has a large volume, a loose structure, a large space required for installation, and a complicated design and installation. The float type liquid level switch pushes the float of the magnet up and down by the buoyancy of the liquid, so that the internal reed switch is opened and closed, so the float has a certain water level, so that the minimum liquid level will be greatly limited. This level switch does not have this limitation.
2. The liquid level switch can be placed up, down, sideways, and diagonally, while the existing float type liquid level switch can only be placed up and down.
3. The liquid level switch liquid level control accuracy is high within ±0.5mm, while the existing float type liquid level switch has an accuracy of ±3.0mm or even higher.
4. No friction, mechanical moving parts, so the reliability is high, and the existing float type liquid level switch float is extremely easy to be stuck and cause bad.
5. The head is smooth and easy to clean.
6. Built-in emitter diode and phototransistor, so long life.
7. The live parts are completely isolated from the controlled liquid, and there is no safety hazard.
1.FS-IR02-PH2.0-NT has no terminal.
2. water level switch sensor deminsion
