SYC21料位开关
SYC21音叉物位开关产品概述
SYC21型音叉式物位开关是一种先进的物位检测仪表，采用振动式测量原理，适用于液体和流动性良好的固体粉料限位检测。该产品由发讯叉体和放大器组成，叉体根部压有两组压电晶体，分别作为驱动器和检测器。驱动器使叉体以固有频率振动，检测器将振动信号转换为电压信号。当物料接触叉体时，振动频率和振幅变化触发继电器输出开关信号，实现高精度物位控制。传感器采用316不锈钢材质，具有良好的耐腐蚀性，可广泛应用于自来水、废水处理、化工溶液等多种工业场景。1
SYC21 Fork Level Switch Product Description
The SYC21 fork level switch is an innovative vibration-based level detection device designed for both liquid and free-flowing solid materials. Its working principle relies on the change in resonant frequency when the fork tines contact the material. The sensor consists of a vibrating fork and an amplifier, with two sets of piezoelectric crystals at the fork base - one for driving vibration and another for signal detection. When material impedes fork movement, the vibration amplitude decreases and frequency shifts, triggering relay output. The 316 stainless steel construction ensures reliable performance in mildly corrosive environments. Typical applications include monitoring levels in矿泉水, paper pulp, dyes,啤酒发酵罐, and柴油 storage tanks. The compact design and simple installation make it suitable for various industrial process control systems.1
技术特点与优势
该产品具有抗干扰能力强、不受介质电参数和密度影响的特性，在结垢、湍流、气泡、振动等复杂工况下仍能稳定工作。独特的压电驱动技术无需机械传动部件，减少了磨损风险。音叉部分经过精密调谐，确保200Hz左右的稳定振动频率，配合智能电路设计的2-7秒可调延时功能，有效消除物料波动引起的误报警。产品采用模块化设计，维护简便，可提供侧装或顶装方式适应不同容器安装需求。对于高温高压环境，特殊设计的叉体可承受300℃过程温度和4.0MPa压力。611
Technical Features and Benefits
This level switch demonstrates exceptional resistance to process disturbances including scaling, agitation, bubbles and medium viscosity changes. The all-solid-state design with piezoelectric excitation eliminates mechanical wear points, ensuring long service life. Precision-tuned forks maintain stable 200Hz oscillation, while adjustable 2-7 second delay prevents false signals from material surges. The modular construction simplifies maintenance, with side-mounted or top-mounted installation options for different vessel configurations. Special fork variants withstand extreme conditions up to 300°C process temperature and 4.0MPa pressure. The measurement remains unaffected by variations in dielectric constant or material density, providing reliable switching for diverse industrial applications from粘稠胶水to粉状原料.621
典型应用场景
产品在食品饮料行业表现优异，特别适用于啤酒、饮料生产中的发酵罐和储罐液位控制。化工领域可测量酸碱溶液、泥浆及易产生气体的液体，造纸行业的纸浆和胶水监测同样适用。对于固体物料，能够可靠检测流动性良好的粉料如水泥、面粉等。危险场所如柴油储罐的物位报警也是其重要应用方向。设备安装灵活，既可通过螺纹连接直接安装在仓壁侧面，也可采用法兰方式固定在顶部避开进料冲击位置，管道安装则可防止泵的空转。16
Typical Applications
The switch excels in food & beverage applications, particularly for啤酒发酵剂and beverage storage tank level control. In chemical processing, it reliably monitors酸碱溶液, slurry and gas-evolving liquids. Paper industry applications include纸浆and adhesive level detection. For solid materials, it effectively measures free-flowing powders like水泥原料and面粉. Hazardous area installations such as柴油tank alarms represent another key application. Flexible mounting options include threaded side-wall installation, flanged top-mounting to avoid material impact, and pipeline mounting to prevent pump dry-running. The vibration principle ensures reliable operation regardless of material conductivity or dielectric properties.122

产品描述
阻旋料位开关也有的称之为阻旋物位计或者阻旋料位开关、阻旋物位开关等，主要是根据它具体的不同用途的不同名称。阻旋式料位开关是采用交流微电机经减速后，带动检测叶片慢速旋转。当被测物料的料位上升使叶片的转动受到阻挡时，检测机构主轴产生旋转位移。此位移先使一个微动开关动作，发出有料的信号。随后另一个微动开关动作，切断微电机的电源使其停止转动。只要仓内的料位不变，此种状态便将一直保持下去。
