Liquid level measurement model D2LS-2A-G, the thread is 3/8 NPT, this is America standard, the theory is infrared. When the optical water level switch detects the liquid level, it must be in contact with the liquid to detect it. When the liquid covers the probe of the optical water level switch, the light emitted by the light-emitting diode in the sensor is refracted in the liquid, and the photosensitive receiver can only receive a small amount of photoelectric light or receive no light. On the contrary, the normal receiving light is in a waterless state.
1) 3/8 NPT thread, it meets America standard.
2) Four points detection.
3) Waterproof cable.
4) High liquid level control accuracy.
5) High reliability.
