? 應(yīng)用鄰域 / Application
魚缸/ fish tank
將傳感器貼在魚缸外側(cè),可用于檢測魚缸滿水或者時(shí)預(yù)感缺水,也可用于控制魚缸液位
Attach the sensor to the outside of the fish tank, which can be used to detect when the tank is full or when it feels short of water, and can also be used to control the tank level
熱水器/ water heater
在熱水器的水箱外部安裝此傳感器,檢測到水箱無水則可以提示或者停止加熱,安全省心。
Install this sensor outside the water tank of the water heater. If it detects that there is no water in the tank, it can prompt or stop heating, which is safe and worry free
咖啡機(jī)/ Coffee machine
在咖啡機(jī)水箱外側(cè)安裝傳感器,用于檢測水箱的水位是否滿足當(dāng)前可使用的標(biāo)準(zhǔn)
Install sensors on the outside of the coffee machine water tank to detect whether the water level in the tank meets the current usable standards
小家電/ Household electrical appliances
空氣蒸鍋,檢測水箱是否有水,當(dāng)水箱無水的時(shí)候提示用戶加水,否則不可以使用,防止干燒燒壞電器,或起火。洗衣機(jī),可以檢測洗衣液或其他物料是否存在,若洗衣液不夠則提示用戶添加洗衣液。印刷機(jī)檢測墨油是否充足。
Air steamer, check if there is water in the water tank. When the water tank is empty, prompt the user to add water. Otherwise, it cannot be used to prevent dry burning, damage to electrical appliances, or fire. A washing machine can detect the presence of laundry detergent or other materials, and prompt the user to add laundry detergent if it is not enough. The printing machine checks whether the ink is sufficient.

? 原理及優(yōu)勢/ Principle and Advantages
1. 原理 / Principle
電容式液位傳感器是利用水和空氣中存在的電荷不一樣來感應(yīng)并區(qū)分容器內(nèi)是否有水的當(dāng)容器內(nèi)無水,則電荷較少,此時(shí)等效于沒有在電容,當(dāng)容器內(nèi)有水,水中帶有大量的電荷此時(shí)相對于空氣能有由一點(diǎn)的容值變化,通過電路對信號的處理,再由算法的計(jì)算和判斷這個(gè)變化,最終輸出當(dāng)前狀態(tài)是否有水。
Capacitive liquid level sensors use the different charges present in water and air to sense and distinguish whether there is water in the containerWhen there is no water in the container, the charge is relatively low, which is equivalent to not being in a capacitor. When there is water in the container and there is a large amount of charge in the water, there can be a slight change in capacitance value relative to air. The signal is processed by the circuit, and the algorithm calculates and judges this change, ultimately outputting whether there is water in the current state.
2. 優(yōu)勢/ Advantages
? 沒有外部參考電容,準(zhǔn)確性高(一般的電容液位傳感器需要一個(gè)外部電容來調(diào)節(jié)靈敏度,而這個(gè)外部電容的精確的本身就無法控制,造成一般的電容式液位傳感器在在出廠時(shí)可用,但是到了一定條件下就不可用。容易造成大量返修)
Without an external reference capacitor, the accuracy is high (typical capacitive liquid level sensors require an external capacitor to adjust sensitivity, and the precision of this external capacitor itself cannot be controlled, resulting in general capacitive liquid level sensors being usable at the factory but unusable under certain conditions. This can easily lead to a large number of repairs)
? 電容式液位傳感器在使用過程中可以不改變水箱的形狀,只需貼合在水箱外側(cè),安裝使用方便
The capacitive liquid level sensor can be used without changing the shape of the water tank, and only needs to be attached to the outside of the water tank for easy installation and use
? 無需與液體直接接觸,不受水垢等液體的因素影響使用
No need to come into direct contact with liquids, and not affected by factors such as scale and other liquids when used
? 靈敏度高,可由軟件進(jìn)行靈敏的的調(diào)節(jié),不用改變外圍電路電容值
High sensitivity, can be adjusted sensitively by software without changing the capacitance value of peripheral circuits
? 體積小,沒有機(jī)械結(jié)構(gòu),無需擔(dān)心使用壽命問題
Small size, no mechanical structure, no need to worry about lifespan issues
? 客戶直接在IO上進(jìn)行檢測即可。無需進(jìn)行復(fù)雜的操做調(diào)試。
Customers can directly perform testing on IO. No need for complex operation and debugging
