Abstract

The invention relates to a conductivity probe, in particular to an intelligent online analyzer probe which mainly comprises a probe, a probe needle, a temperature measuring element, a probe holder andan intelligent memory circuit board, wherein the probe needle penetrates through a probe rod and is fixed and contacts with a measured medium by three pairs of waist-shaped through holes on the proberod; the temperature measuring element is installed in the probe near the front end for measuring the temperature of the medium; the intelligent memory circuit board for storing parameters is installed in a press cover of the probe; the probe is connected with a measuring meter by a twelve-core shield cable; after the probe is connected with the meter and the meter is powered on, the meter automatically read parameter data in an intelligent chip of the probe and is automatically matched with the probe without artificially regulating parameters of the meter; the probe needle is made of Pt metal materials, and other devices contacting with the measured medium are made of polytetrafluoroethylene; and multi-leakageproof sealing design is applied to the probe. The intelligent online analyzer probe provided by the invention has the advantages of safety, reliability, intellectualization, strong acid and alkali-resistant mediums and long service life and is suitable for using in special environments in the industrialized field, such as strong acid and alkali mediums.

Description

technical field [0001] The invention relates to on-line measurement, in particular to on-line analysis of strong acid and strong alkali media. Background technique [0002] At present, in the chemical production and sewage treatment industry, the water content of the medium or the concentration of the medium through the conductivity measurement is widely used, which greatly facilitates people's needs for product quality control and environmental protection pollution discharge. [0003] The principle of measuring the moisture content of the medium or the concentration of the medium through the conductivity is to use the principle that there is a certain correspondence between the concentration of the medium and the conductivity, and input the data table of the conductivity of the measured medium and the concentration of the medium into the meter, and then the meter Measure the conductivity of the measured medium, and convert it into the concentration value of the medium by lo...
