50DP型的差压变送器(美国西屋公司) 这种电子式差压变送器是借由差压引起的测量膜片的位移转换成差压变送器的衔铁动作,从而使电感变化,并经电子电路转换成电流信号.
50DP-type differential pressure transmitter (Westinghouse) The electronic differential pressure transmitter is caused by the differential pressure measurement diaphragm displacement into differential pressure transmitter armature action, so that the inductance changes, And by the electronic circuit into a current signal.
