JTK61KA料位开关
JTK61KA音叉物位开关产品介绍
JTK61KA音叉物位开关是一种基于音叉共振原理设计的物位检测设备，适用于各类料仓固体物料料位及容器内液位的定点报警或控制。该产品由发讯叉体和放大器两部分组成，叉体根部装有两组压电晶体，分别作为驱动器和检测器，通过驱动叉股产生振动并检测振动状态变化来实现物位测量。其核心特点是振幅可调，能够适应不同状态和密度的物料，包括固体颗粒如水泥、石粉、塑料颗粒，以及液体介质如水、泥浆、油类等。产品采用无机械可动部件设计，安装简便且具备防腐特性，灵敏度高，能有效检测液体中的沉淀物。工作过程中，当叉股接触物料时振动幅度会急剧减小，从而触发继电器输出开关信号。13
JTK61KA Fork Level Switch Product Introduction
The JTK61KA fork level switch is a point-level detection device based on tuning fork resonance principle, suitable for solid material level monitoring in silos and liquid level control in various containers. Its vibrating fork consists of a transmitter body and amplifier, with two sets of piezoelectric crystals installed at the fork root - one as the driver to generate vibration and another as the detector to convert mechanical vibration into electrical signals. This design allows adjustable amplitude to accommodate materials with different densities and states, including solid particles (cement, plastic pellets) and liquids (water, oil, slurry). The all-stainless steel construction ensures corrosion resistance while the no-moving-part design minimizes maintenance needs. When the fork contacts materials, vibration amplitude decreases sharply, triggering relay output for alarm or control purposes. The compact structure and flexible installation options make it widely applicable in food, chemical and construction industries.13
产品功能特点
该设备具备多项实用功能：1）独特的叉体设计能自动清除挂料，最大限度防止误报警；2）支持顶部垂直安装或侧向倾斜15-20度安装，可加装挡板减少物料冲击；3）适用于高温工况，部分型号可耐250℃高温；4）电子线路采用SMT表面贴装技术，抗潮湿和振动干扰能力强。对于特殊应用场景如核电站辅助系统，还可提供增强型设计。产品出厂前经过严格测试，确保在粉尘、粘附性物料等复杂环境下稳定工作，且不会因物料堆积产生误动作。31219
Functional Features
Key advantages include: 1) Self-cleaning fork design prevents material buildup and false alarms; 2) Multiple installation options (vertical top-mount or 15-20° tilted side-mount) with optional protective baffles; 3) High-temperature models available for processes up to 250°C; 4) SMT-assembled electronics ensure reliable performance in humid/vibratory environments. For critical applications like nuclear power plant auxiliary systems, enhanced versions with reinforced construction are offered. Pre-delivery testing guarantees stable operation under challenging conditions including dusty or sticky materials, with immunity to accidental triggering caused by material bridges. The smooth cylindrical probe surface further improves material shedding capability.121419
典型应用场景
该产品在工业领域有广泛适用性：固体物料监测可覆盖粮食仓储中的大米、奶粉，建材行业的水泥、石粉，以及化工领域的塑料颗粒、染料等；液体介质检测包括水处理厂的泥浆、纸浆，食品饮料行业的牛奶、酒类，以及石油化工中的各类油品。在安装方式上，针对流动性差的物料建议采用倾斜安装并设置防护挡板，对于易产生桥接现象的粉体可缩短探头与仓壁距离（≤60mm）。设备提供标准螺纹或法兰过程连接，满足不同容器接口需求。1321
Typical Applications
Widely adopted across industries: for solid materials like grain (rice, flour), construction materials (cement, sand) and chemical products (plastic pellets, dyes); for liquids including wastewater treatment sludge, paper pulp, food-grade liquids (milk, alcohol) and petrochemical oils. Installation recommendations: inclined mounting with protective baffles for cohesive materials, close-to-wall mounting (≤60mm gap) for bridging-prone powders. Standard thread or flange process connections accommodate various vessel interfaces. The product s vibration-based principle ensures reliable detection regardless of material color, dielectric constant or conductivity changes.31822
JTK61KA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。
