DPF—100系列是以差压变送器为中心的电子式差压、压力变送器的总称。它成功地采用了差动电容方式将位移变换成电信号输出,是日本于1974年间以自力开发研制的。该系列变送器,机种多样,适宜测量差压、压力、液位、绝对压力等各种工艺过程变量。开方型差压变送器,是 DPF—100系列中的一种,由原来的差动电容式检测器附加
DPF-100 series differential pressure transmitter is the center of the electronic differential pressure, pressure transmitter in general. It succeeded in using the differential capacitance method to transform the displacement into electrical signal output, developed by Japan in 1974 to self-developed. The series of transmitters, models and diverse, suitable for measuring differential pressure, pressure, liquid level, absolute pressure and other process variables. Square root type differential pressure transmitter, is a DPF-100 series, the original differential capacitance detector attached
