Application of Photoelectric Liquid Level Switch in Robotic Process Automation System [Copy link]

Industrial robots are used in a variety of applications from vehicle manufacturing to semiconductor pick and place. Any repetitive task is a candidate for automation, especially when it comes to hazards to humans or in harsh environments. This protective induction will be very obvious. This article mainly focuses on the application of photoelectric level switches in protecting robot process automation systems. What are the problems with industrial robot systems? The oil within the industrial robot system is used to lubricate joints and gears, prevent overheating, misalignment and bearing wear. If these oils leak during operation, they may contaminate the surrounding environment, damage production and affect machine performance. Industrial robot systems are very expensive to install, and it is critical to operate and maintain them correctly, where any "downtime" can be costly! Detecting leaks at an early stage prevents unnecessary costs, improves end-user confidence, and adds value to your customer's product or service. The single-point optical level switch technology of the LLC200D324-003 provided by Gongcai.com provides a reliable and cost-effective solution to detect the presence of any fluid. Switching high or low levels during operation can be quickly and easily integrated with the control system. Located in a gearbox to maintain a minimum level, or in an oil pan to detect the absence of oil, the switch will provide an almost instantaneous indication of the problem. With no moving parts to wear, resistance to high temperatures and pressures, and requiring only 1mm of fluid to open or close the tip, the switch can protect robotic systems from damage.

How it works

When the tip of the switch is in air, infrared light reflects inside the tip to the phototransistor, providing strong optical coupling between the two. When the tip is in liquid, infrared light escapes from the tip, causing the amount of light in the phototransistor to decrease, triggering a change in the output state.

Therefore LLCindustrial-grade liquid level sensor is a single-point detection, TTLcompatible digital level signal output. This sensor is suitable for high-power output applications and can directly drive incandescent lamp indicators, sound alarms, relays or other situations. An infraredLEDlight source and photoelectric tube detector are precisely mounted on the base of the sensor end to ensure good optical coupling in the air. When the sensing end is immersed in liquid, the infrared light will be transmitted from the conical surface, and the light intensity received by the photoelectric tube will decrease, resulting in a change in the output level. A variety of output circuits can meet different application scenarios.
