APX501料位开关
产品概述
APX501音叉液位开关是一款基于压电晶体与叉体谐振原理设计的高性能物位检测设备，适用于液体、颗粒状固体、浆液及粉末状物料的液位控制与报警。该产品通过感应叉体频率及相位变化实现精准信号采集，经集成电路处理后输出开关信号，广泛应用于化工、医药、食品、造纸、冶金等行业的生产过程自动化控制。其核心优势在于恶劣环境下仍能保持稳定工作，安装后无需调校和维护，为用户提供长期可靠的监测解决方案。147
技术特点
APX501采用316不锈钢或哈氏合金材质叉体，耐腐蚀性强，可适应-40℃至180℃的环境温度。产品提供24VDC和220VAC两种电源选择，标配继电器接点输出（DPDT双刀双掷），支持灵敏度与延迟时间手动调节。独特设计的短音叉结构（最小叉长40mm）特别适用于管道或狭窄空间安装，对低至0.5g/cm³密度的介质仍能准确检测，包括盐酸、硫酸、碱液等高腐蚀性液体以及易产生泡沫、气泡的复杂工况。内置LED状态指示灯可直观显示设备运行状态。369
工作原理
当音叉接触物料时，压电晶体驱动的谐振频率会发生显著变化，内部智能电路实时监测这种变化并转换为开关信号。该设计使APX501能够完全不受流体湍流、气泡、粘附或振动干扰的影响，确保检测结果真实可靠。对于固体物料如水泥、塑料颗粒等，可通过调整振幅适应不同密度；对于液体介质如牛奶、酒类等，其快速滴落式叉体设计能有效应对粘稠液体。21114
应用场景
典型应用包括压缩机高温油位监测、石化储罐高低位报警、制药行业反应釜料位控制、食品加工流程中的液位管理等。在颗粒物料场景下，可检测米、糖、盐、饲料等；在液体场景中适用于水、泥浆、染料、油类等多种介质。产品提供螺纹或法兰安装方式，水平或垂直安装均可满足，特别设计的卫生型连接件符合食品行业要求。101527
Product Overview
The APX501 tuning fork level switch is a high-performance detection device based on piezoelectric crystal and fork resonance principle, designed for liquid, granular solid, slurry, and powdered material level control. By monitoring frequency and phase changes of the vibrating fork, it delivers accurate switching signals through integrated circuit processing. Widely applied in automation systems for chemical, pharmaceutical, food processing, papermaking, and metallurgical industries, this device maintains stable performance even in harsh environments without requiring calibration or maintenance after installation. 157
Technical Features
Constructed with 316 stainless steel or Hastelloy fork material, the APX501 withstands corrosive media and operates reliably within -40℃ to 180℃. It offers dual power options (24VDC/220VAC) with standard DPDT relay output, featuring adjustable sensitivity and delay time. The compact fork design (minimum 40mm length) suits pipeline or confined space installations, accurately detecting low-density media (≥0.5g/cm³) including aggressive fluids like acids, alkalis, and frothy liquids. Integrated LED indicators provide real-time operational status. 3612
Operating Principle
Material contact alters the resonant frequency driven by piezoelectric crystals, which is instantly converted into switching signals by onboard smart circuitry. This mechanism ensures immunity to flow turbulence, bubbles, coating, or mechanical vibrations. For solids like cement or plastic pellets, adjustable amplitude accommodates varying densities; for viscous liquids such as syrups, the quick-drain fork design enhances response speed. 21114
Applications
Typical uses include compressor oil sump monitoring, high/low level alarms in petrochemical tanks, reactor vessel control in pharmaceuticals, and liquid process management in food production. It handles granular materials (e.g., grains, sugar) and diverse liquids (water, slurries, oils) with equal efficacy. Available with threaded or flanged connections, the switch supports horizontal/vertical mounting, while sanitary fittings meet food-grade requirements. 101630

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。
