Description


The main component of a 24v optical level sensor is a wear-resistant polymer or glass head with an infrared (IR) light source and an optical detector. When the tip is in the air, infrared light is reflected to the inside of the sensor tip and is reflected to the optical detector. In contrast, when immersed in liquid, this infrared light is refracted from the tip, and the optical signal is weakened.

24V optical level sensor is a three-wire type sensor. Generally, the three-wire submersible infrared level switch has a built-in resistance, it is not necessary to bring a resistance when wiring. This type of submersible infrared level switch has the characteristics of no debugging and no calibration, it can be used after installation.


Application


In agricultural irrigation systems, the main role of liquid level sensors is to monitor water levels. The sensor is generally located at the top and lower part of the water tank. The liquid level sensor will automatically detect the depth of the water layer and transmit the collected data to the intelligent irrigation control system in real time through the wireless transmission device. After the system diagnoses, the decision-making instructions issued are transmitted to the irrigation control device in the field, and then the water in the pool will be automatically poured into the rice field. When the water level drops to this point, the output of the liquid level sensor will change, thereby triggering the alarm system in the irrigation system, and cutting off the power supply of the working circuit, saving irrigation water and improving water resource utilization.


24v optical level sensors provide single-point liquid level detection, specially designed for high-volume OEM customers. The sensor contains an infrared emission source and a detector, and the installation position is accurate to ensure that the two achieve good optical coupling in the air. When the tapered end of the sensor is immersed in liquid, infrared light will be transmitted out of the tapered surface, and the intensity of the light reaching the detector will be weakened. During irrigation, users can design corresponding circuits according to their needs to ensure the normal operation of agricultural irrigation.
