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料位开关
阻旋料位开关产品原理：阻旋料位开关是一种用于固态物料（包括粉状、粒状、块状、胶状等）的物位控制器。其利用永磁电机带动叶片旋转，当被检测物料上升至叶片位置时，叶片转动受阻，该阻力通过传动轴传递到接线盒内的检测装置，检测装置则向外输出一个开关信号，并切断电机电源使叶片停止转动。当物料下降时，叶片阻力消失，检测装置便依靠弹簧的拉力恢复到原始状态，叶片恢复旋转状态。在化工、塑料、钢铁、电力、水泥、制药、饲料、食品等行业得到了的应用。
