RZ37料位开关
产品概述
RZ37阻旋式料位开关是一种用于固态物料(包括粉状、颗粒状、块状等)位置检测的现场控制设备。该产品通过电机驱动叶片旋转,当物料接触叶片时,旋转受阻触发开关信号,实现料位高低限位的监测功能。其结构设计兼顾可靠性与环境适应性,可广泛应用于饲料、食品、化工、塑料、建材等行业的物料存储与输送过程。123
工作原理
该设备采用永磁电机带动不锈钢叶片低速旋转(1转/分钟)。当物料上升至叶片位置时,旋转受阻产生的阻力通过传动轴传递至检测机构,触发开关信号并切断电机电源;物料下降后,弹簧机构使叶片复位并恢复旋转状态。针对不同密度的物料,可通过调节扭力弹簧的拉力实现灵敏度适配,确保检测准确性。3411
产品特点
RZ37料位开关采用SUS304不锈钢叶片和IP65防护外壳,具有防尘防潮特性,适用于-10℃至80℃环境(特殊设计可耐400℃高温)。其机电分离式结构便于维护,离合器过载保护装置可避免电机因意外卡阻损坏。水平安装时建议叶片与水平面呈10-20°夹角,以减少物料冲击。产品提供220VAC/110VAC/24VDC等多种电源选项,触点容量为10A/250VAC。1615
典型应用
该设备在粉煤灰仓、粮食储罐、塑料粒子料斗等场景中表现稳定,能有效防止物料溢出或空转。钢缆型设计特别适用于深仓或需要柔性安装的场合。安装时需避开进料口直冲位置,必要时可加装防护挡板延长使用寿命。21020
Product Overview
The RZ37 rotary paddle level switch is a field control device designed for detecting solid materials (including powders, granules, and bulk solids). It utilizes a motor-driven rotating paddle that stops upon contact with materials, generating switch signals for level monitoring. With robust construction and environmental adaptability, it suits applications in feed processing, food production, chemical plants, plastic manufacturing, and building material industries.1321
Working Principle
A permanent magnet motor rotates the SUS304 stainless steel paddle at 1 RPM. When material obstructs the paddle, the resulting torque change activates the switching mechanism while cutting power to the motor. After material retreats, a return spring resets the paddle. The adjustable torque spring allows sensitivity calibration for materials with densities ≥0.5g/cm³, ensuring reliable detection across varied applications.41112
Key Features
The device features dustproof IP65 enclosure and operates within -10℃ to 80℃ (optional 400℃ version available). Its split mechanical-electrical design simplifies maintenance, with slip clutch protection preventing motor damage during overload. For horizontal installation, a 10-20° downward tilt angle is recommended to minimize material impact. Compatible with 220VAC/110VAC/24VDC power supplies, it provides SPDT contacts rated 10A/250VAC.61519
Typical Applications
This cable-type switch excels in deep silos or flexible mounting scenarios, commonly deployed in fly ash bunkers, grain storage systems, and plastic pellet hoppers. Proper installation avoids direct material impact zones, with optional protective baffles enhancing durability in high-flow areas. The design effectively prevents both overfilling and equipment dry-run conditions.21020

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。
