Optical Sensors are devices used to detect the presence of an object within an industrial environment or an area, by receiving and processing light. The 70156-4047 is a type of photoelectric optical sensor designed for detecting liquid levels within containers or pipes, and it operates dependently upon the amount of light reflected off the surface of the liquid.

This type of optical sensor contains two distinct elements: an emitter and receiver. The emitter is a light source usually composed of LEDs or light emitting diodes that are used to emit infrared light in a specific direction. The receiver acts like a photocell and has two distinct parts. One is a focusing lens which receives and works with the light beam emitted by the emitter, whereas the other is the photodiode which converts the received light beams into electrical signals.

The 70156-4047 operates with an analog controller based upon the amount of reflected light, according to the level changes within the container or pipe. The sensor works by emitting the light beam through the container or pipe, then measuring the amount of light reflected from the liquid’s surface. If the liquid level is too low, then the reflected signal will be low as it is not able to reach the surface of the liquid. However, if the liquid level is too high, the reflected signal will be high as the entire length of the liquid is able to reflect light more efficiently.

The underlying principle is that the reflectivity of the light beam from the emitter can be measured and used to determine the liquid level within the container or pipe. The 70156-4047 optically senses the changes in liquid level by continuously adjusting the threshold level of the reflectivity of the light beam. When the level of the liquid is reached, the analog controller activates the electronic switch which controls the liquid level within the container or pipe.

The 70156-4047 optical sensor is generally used in industrial and automotive applications, such as controlling fuel levels in cars or detecting the level of liquid in tanks. The sensor is designed to provide high accuracy and reliable operation, and it has been widely utilized in many production lines in various factories. Moreover, this sensor can also be used in process monitoring applications, such as to detect liquid levels within pipes, tanks and other containers within industrial or manufacturing environments.

The 70156-4047 optical sensor is an easy to use and efficient device for detecting and monitoring liquid levels within containers or pipes. This type of sensor uses an analog controller to measure the reflected light from the surface of the liquid, offering reliable accuracy and response time for controlling liquid levels in industrial and automotive applications. It is a highly efficient device that can be used in many production lines and can prove to be an invaluable asset in process monitoring applications, where accurate and reliable liquid level detection is important.
