    • The invention relates to a grid sensor comprising wiry electrodes for measuring the electroconductivity of a flow medium in the cross-section of a pipeline. The invention can be especially applied where the flow medium flows at a high pressure and at high temperatures. According to the invention, each electrode wire (3) is mechanically connected to a spring (2) on one side by means of an insulating bead (4), said spring being arranged in a hole in the sensor body having an axis which is oriented in the tensioning direction of the wire, and fixed to the sensor body in this position. Each electrode wire on the side opposing the spring (2) is covered with an insulating tube (6) arranged in an outwardly guided channel in the sensor body. The insulating tube ends inside said channel, in a cavity (7) filled with a sealing material. Neither the insulating bead (4) on one side nor the insulating tube (6) on the other side are located in the cross-section wherein the measurement is to be carried out.
    • 本发明涉及一种传感器网格以用于测量流动介质的电导率在管道的横截面的线状电极。 本发明的应用被赋予特别是在流动介质在高压下和高温下的流动。 本发明包括每个电极导线(3)的通过绝缘凸缘(4)机械地连接到弹簧(2),它位于在一个孔中的传感器主体,其轴线上的点在导线的夹持方向并且有在一侧连接 传感器主体被安装,使得每个在其上的弹簧(2)相反的一侧覆盖有位于在传感器主体的引出通道的绝缘管(6)的电极导线,在所述通道内的空腔(7)的绝缘管 结束时,其填充有密封剂,并且也不在一个仍然在上在测量部分中的另一侧上的绝缘管(6)的绝缘凸缘(4)。
