LS-YC-P-0料位开关
产品概述
LS-YC-P-0音叉式物位开关是一种通用型料位检测设备，采用压电晶体激励原理实现非接触式测量。该产品通过音叉振动频率变化检测物料位置，适用于液体、粉料及颗粒状介质的限位报警与控制。其独特设计使测量不受介质电参数、密度、结垢或搅拌等因素影响，在石化、冶金、食品、建材等行业中表现稳定可靠。134
工作原理
产品由发讯叉体和放大器组成，叉体根部压装两组压电晶体：一组作为驱动器激发音叉振动，另一组作为检测器转换振动信号。当物料接触音叉时，振动频率发生突变，电子线路捕捉该变化并输出开关信号。整个过程无需机械传动部件，避免了传统浮球或阻旋开关的磨损问题，实现免维护运行。257
技术特点
该料位开关具备优异的工况适应性，可在-30℃~150℃介质温度范围内稳定工作，耐受2MPa压力环境。316不锈钢材质的叉体设计能抵抗轻度腐蚀，且振动特性具有自清洁功能，有效防止物料挂料。产品提供1~20秒可调输出延时功能，支持AC220V或DC24V供电，继电器输出可直接控制设备启停。安装方式灵活，支持侧装、顶装及管道安装，特别适合不便开孔的容器。468
典型应用
广泛应用于自来水厂监测水位、啤酒发酵罐液位控制、化工酸碱溶液报警、粮食仓储粉料检测等场景。在纸浆、胶水、染料等高粘度介质，以及柴油等危险场所中同样表现优异。其紧凑结构可替代传统浮球开关，尤其适用于存在湍流、气泡或振动干扰的复杂工况。2922
Product Overview
The LS-YC-P-0 tuning fork level switch is a versatile material detection device utilizing piezoelectric excitation technology for non-contact measurement. Designed to monitor liquid, powder and granular materials, it detects level positions through vibration frequency shifts, offering reliable performance in petrochemical, metallurgy, food processing and building material industries without being affected by dielectric properties or density variations. 357
Operating Principle
Featuring a vibration fork and amplifier assembly, the device employs two piezoelectric crystal sets: one as driver to generate vibrations and another as sensor to convert mechanical signals. Upon material contact, the frequency change triggers electronic circuitry to output switching signals. The all-electronic design eliminates moving parts, ensuring maintenance-free operation compared to mechanical float or paddle switches. 168
Key Features
This level switch demonstrates remarkable environmental adaptability, operating within -30℃~150℃ medium temperature range and 2MPa pressure conditions. The 316 stainless steel fork resists mild corrosion while its vibration characteristics prevent material buildup. Adjustable delay output (1-20s) and dual power options (AC220V/DC24V) with relay outputs facilitate direct equipment control. Flexible side/top/pipeline mounting suits various vessel configurations. 4922
Typical Applications
Ideal for water plant level monitoring, brewery fermentation control, chemical acid/alkali alarms and grain silo powder detection. Performs consistently with viscous media like pulp, glue, dyes, and hazardous areas including diesel storage. Its compact design replaces traditional float switches, particularly effective in turbulent, bubbly or vibrating environments. 257
LS-YC-P-0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。
