Product Introduction of L8700 Fork Level Switch (English)
The L8700 Fork Level Switch is a highly sensitive level detection device based on the tuning fork resonance principle, utilizing advanced SMD production technology and electronic circuitry. By employing piezoelectric elements to drive the fork vibration, the device triggers a switching action when the probe is fully surrounded by material, causing a significant reduction in vibration amplitude. Its unique design provides excellent resistance to material buildup and impact, making it suitable for level detection in various complex working conditions. The product is constructed with 316 stainless steel and offers multiple material contact options including standard, sanitary, and corrosion-resistant types, allowing users to freely select according to actual needs. The L8700 features status indicator output with adjustable sensitivity and action delay time, while its high-frequency excitation technology ensures superior anti-noise interference capability. This level switch can detect powders and small particles with densities as low as 0.2g/cm³, as well as liquids with viscosity up to 10000mm²/S, finding wide applications in industries such as dust collectors, ash hoppers, plastic/rubber powders, and food processing.14812

L8700料位開關
阻旋料位開關產品原理：阻旋料位開關是一種用于固態物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機帶動葉片旋轉，當被檢測物料上升至葉片位置時，葉片轉動受阻，該阻力通過傳動軸傳遞到接線盒內的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電機電源使葉片停止轉動。當物料下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態，葉片恢復旋轉狀態。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業得到了的應用。
