开滦范各庄矿选煤厂,从西德E+H公司引进68台电容绳式料位计。其中FMC—280型电容绳式料位计14台,分别用于选煤厂离心液池、饮用水箱、清水箱、澄清水箱、循环水箱、循环式真空泵冷却水泵池、尾煤与中煤浓缩机澄清水泵池、循环水箱下定压水箱等场所的液位连续测量。FMC-280型液位计除具有模拟指示外,还可输出0-5伏标准电压信号、输出0-20毫安电流信号,便于与调节器、
Kailuan Fangezhuang coal preparation plant, from Western Germany E + H company introduced 68 capacitive rope level meter. Including FMC-280 capacitive rope level gauge 14, respectively, for the coal preparation plant centrifugal pool, drinking water tank, water tank, clarification tank, circulating water tank, circulating pump vacuum pump pool, tailings and coal concentration Machine to clarify the pump pool, circulating water tank under constant pressure water tank and other places of continuous measurement. FMC-280-type liquid level gauge in addition to analog instructions, but also output 0-5 volts standard voltage signal, the output 0-20 mA current signal, with the regulator,
