RZ系列阻旋式料位开关  的详细介绍

RZ系列阻旋式料位开关


一、产品简介
阻旋式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。它具有密封性好、过载能力强(具有过载保护)、轻便易装、输出触点容量大等特点。针对不同比重的物料可通过调整弹簧的拉力来实现,其接触物料部分全为不锈钢材料。阻旋式料位开关在化工、塑料、水泥、制药、饲料、食品等行业得到了广泛的应用。

二、工作原理
        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。针对使用于比重相差较大的物料,可调整弹簧拉力,比重大时弹簧拉力调整至*强,反之则调整至*弱。

The10 device is a non-invasive ultrasonic flowindicator and switch which is able to monitor process liquidswithout penetrating the surface of the pipe. The sensor issimply attached to the outside of the pipe and measurementsare made through the pipewall. There is no need to drillholes or to perform any welding to install the sensor.Installation time and cost are negligible as a result.

The  10 utilises ultrasonic Doppler technology toprovide cost effective and repeatable switch point outputsfor high or low flow alarm. Ultrasonic pulses are transmittedand received by the unit through the pipewall and into thefluid. Signal reflections from particles and air inclusions inthe liquid cause a frequency shift of the transmitted ultrasoundwhich is proportional to the flow rate of the medium.
The 10 is capable of operating in general purposeflow measurement applications with velocities from 0.3 m/sto 3.5 m/s on many liquids and slurries. It is possible on themajority of liquids, to indicate the flowrate and provide arepeatable switching point on higher or lower than desiredflow.Each unit has ease ofinstallation and calibration as a keyfeature, having a single button set-up with status feedback
during initial calibration from red and green LED's.
