Abstract

The invention discloses a high-conductivity graphite sensor, and belongs to the technical field of solution conductivity measurement. The high-conductivity graphite sensor comprises a threaded liquid inlet pipe, a first graphite electrode, a first spiral pipe assembly, a second graphite electrode, a second spiral pipe assembly, a third graphite electrode and a threaded liquid outlet pipe. A pair of platinum wire electrodes parallel to the graphite electrodes are arranged on the first spiral pipe assembly or the second spiral pipe assembly. The platinum wire electrodes penetrate out from the interior of spiral pipe assemblies and then are connected with a varnished wire. The first graphite electrode, the second graphite electrode and the third graphite electrode are each provided with an electrode lead, and temperature sensors are installed on the graphite electrodes. The high-conductivity graphite sensor has the advantages that the structure is simple, measurement of the conductivity of a high-conductivity solution is more precise, the length of the sensor can be adjusted, and the sensor is not limited by the installation space.

Description

technical field [0001] The invention belongs to the technical field of conductivity measurement of solutions, in particular to the conductivity measurement of high conductivity solutions. Background technique [0002] Conductivity sensors are widely used in the measurement and detection of the properties of industrial circulating water, human domestic water, seawater, electrolyte in batteries and other substances. For the measurement of the conductivity of a solution with high conductivity, it is more accurate to use a seven-electrode sensor. However, for the existing seven-electrode sensors, it requires a symmetrical structure, so the measurement results are affected by processing, the accuracy is large, and the production is difficult and the cost is high; The length affects the sensor volume, which in turn causes the measurement range to be limited by the sensor structure. Contents of the invention [0003] In view of the above problems, the present invention provides...
