产品介绍

Description

HD181S系列射频电容液位变送器是我公司吸收国外同类产品的技术精华研制而成的新型液位测量仪表。它可将各种物位、液位介质参数的变化转换成标准电流信号、远传至操作控制室,供二次仪表或计算机装置进行集中显示、报警或自动控制。其良好的结构及安装方式,可适用于高温、高压、强腐蚀、易结晶、防堵塞、防冷结以及固体粉状、粒状物料等特殊条件下的液位、料位、物位的连续测量,广泛应用于电力、冶金、化工、食品、制药等行业和污水处理、锅炉汽包、煤粉包等场所的液位、料位及物位测量。
HD181S Series RF Capacitive Level Transmitter is a new type of liquid level measuring instrument developed by our company absorbing the essence of similar products from abroad. It can convert all kinds of level and liquid medium parameters into standard current signals and remotely transmitted to the operation control room for centralized display, alarm or automatic control of secondary instruments or computer devices. Its good structure and installation method can be applied to the continuous measurement of liquid level, material level and material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-blocking, cold-resistance and solid powder, granular materials and other special conditions, which is widely used in electric power, metallurgy, chemical, food, pharmaceutical and other industries and sewage treatment, the liquid level, material level and level measurement of boiler drum, pulverized coal etc..
