UQZ型系列浮球液位变送器

      

UQZ型浮球液位变送器由磁性浮球、测量导管、测量元件、电路单元、接线盒外壳及安装件等部分组成。浮球与液位同步变化，通过磁耦合作用，使传感器内电阻呈线性变化，再由转换器将电阻变化转换成电流放大至4～20mA二线制标准信号输出，实现被测液位的远距离检测和控制。测量元件采用先进的磁阻磁开关，稳定可靠，抗干扰能力强，变送电路具模块化结构，测量精度全系列进入5mm内。

The UQZ type floating ball liquid level transmitter consists of magnetic floating balls, measuring conduits, measuring elements, circuit units, junction box shells, and installation parts. The floating ball changes synchronously with the liquid level, and through magnetic coupling, the resistance inside the sensor changes linearly. Then, the converter converts the resistance change into a current and amplifies it to a 4-20mA two-wire standard signal output, achieving remote detection and control of the measured liquid level. The measuring element adopts advanced magnetoresistive magnetic switch, which is stable and reliable, with strong anti-interference ability. The transmission circuit has a modular structure, and the measurement accuracy of the entire series is within 5mm.
