Abstract
A grid sensor including grids of electrode wires for measuring the electroconductivity of flow medium in the cross-section of a pipeline is particularly suitable for applications where the flow medium flows at high pressure and high temperatures. Each of the electrode wires is connected to a spring via an insulating bead, the spring being arranged in a hole in a sensor body of the sensor having an axis which is oriented in a tensioning direction of the electrode wire, and fixed to the sensor body. Each of the electrode wires on the side opposing the spring is covered with an insulating tube arranged in an outwardly guided channel in the sensor body. The insulating tube ends inside the channel, in a cavity filled with a sealing material. Neither the insulating bead nor the insulating tube are located in the cross-section wherein the measurement is to be carried out.
