I. Application of Switch Sensors
Switch sensors have wide applications in many fields, including but not limited to the following:
Industrial Automation: In automated production lines and robotic systems, switching sensors are used for control, detection, measurement, and alarm functions. This includes detecting the status of the product manufacturing process, measuring temperature, pressure, flow rate, etc.
Material detection and production line control: Switch photoelectric sensors can be used to detect items in logistics and production lines, enabling automated material selection, sorting, and counting functions. They can also be used for production line operation control to prevent abnormal situations and ensure the normal operation of the production line.
Safety monitoring: In the safety performance monitoring of robots and other high-speed moving equipment, switch photoelectric sensors help to avoid accidental human contact and machine malfunctions.
Smart Home: Switch sensors are used in these areas including door and window detection, smart lighting control, and the control of automated home appliances. For example, they can be used to detect indoor light intensity and control light brightness, or to monitor the activities of family members to automatically adjust home appliances.
Other applications: Switch sensors are also widely used in various industry engineering projects such as ranging, counting, and conversion, including assembly lines, material handling, and vehicle safety inspection.
II. Function of Water Level Switch Sensor
When it comes to water level switch sensors, few people may know about them, as they are a relatively unfamiliar concept to us. However, don't underestimate water level switch sensors, because in many situations, our water level switches rely on them to start working. Therefore, understanding water level switch sensors is essential. So, what are the functions of water level switch sensors, and what types of water level switch sensors are there? Let's hear what the editor has to say.
When water is added to the outer tub, the connection between the outer tub and the water level switch is sealed. As the water level rises, the pressure in the air pipe gradually increases. This pressure, through the air nozzle of the water level switch, exerts a force on the diaphragm within the switch. When the force reaches the set mark, the pin connected to the diaphragm pushes the contact strip, causing it to deform and close, thus controlling the water level. Specifically, under air pressure, the spring contacts and sends a signal to the control board, initiating the washing cycle. The water level switch's task is now complete. If the water level drops during the washing process, the spring contacts open, sending a signal to the control board to replenish water to the set level.
If the airtightness is poor, the pressure in the air pipe will deviate from the actual requirement (below the required level), resulting in an excessively high water level. When the user selects the highest water level, the water will overflow from the edge of the outer tank due to excessive water injection, causing a continuous water inflow fault. If the spring of the water level switch cannot be reset after being pushed up, it will cause a failure to spin dry.
The water level switch is powered by 24VDC and has one relay switch active output (24VDC). When the lower water level sensor detects no water, the relay switch closes and starts the water pump to pump water; the relay switch only opens and the water pump stops pumping water when the upper water level sensor detects water.
The liquid level control switch can be equipped with three types of liquid level sensor probes: FS-IR02, FS-IR12, FS-IR32A, and FS-IR42. The biggest difference between these three sensors lies in their installation type.
The surface materials of the equipped liquid level sensors are all made of PC and polysulfone, and are suitable for various liquid level measurements. Except for strong acids, strong alkalis, and other corrosive liquids, they cannot be used; such as: sulfuric acid, hydrochloric acid, nitric acid, KOH, NaOH, etc.
The liquid level switch employs advanced circuit design and program optimization to eliminate the influence of external factors such as scale, water vapor, and water droplets on measurement accuracy. Of course, regular maintenance and cleaning are also essential.
