SMES Mendeleevets - Reference electrode of long operation

SMES - Reference electrode
SMES - Reference electrode
Included in the registers:
Included in the register of GAZPROM

Certification:

Certified in the INTERGAZCERT Favourable decision of a Sanitary-hygienic Commission of Experts

Application area

Copper-sulphate comparison electrodes Mendeleevets are used in electrochemical systems of protection against corrosion and to measure the capacity of underground metallic structures.

Reference electrodes are stationary and installed in the soil to a depth of laying pipelines below the freezing depth of the soil. Measurements of potential are carried out in accordance with the requirements of GOST (Federal Standard) 9.602-2005. The reference electrodes are manufactured in climatic design U category 1 GOST (Federal Standard) 15150.

Technical details

SMES-2

1 – internal body;
2 – thermocontracting coupler;
3 – measuring cable;
4 – cable tip;
5 – bentonite mix;
6 – external body

The body of the reference electrode is made of special porous ceramic that provides a low contact resistance and a stable potential value.

The internal body of the reference electrode filled with copper sulfate. Inside the copper sulfate there is a copper electrode of spiral shape to increase the contact area.

The reference electrode is equipped with measuring wires, mark VPP 1x6.

The reference electrode body is filled with the water-holding filler based on the bentonite to provide more stable operation and longer life in various soil conditions (dry soils, flooded soils, saline soils, etc.).

Using the reference electrodes SMES-2 with the auxiliary electrode (VE) allows to measure polarization potential by disabling the auxiliary sample polarization current according to Federal Standard (GOST) 9.602.

To make service easier the cable outlets are marked and equipped with terminals for connection to Control Testing machine. The measuring cable is a load-carrying element in the structure of the reference electrode SMES and it is used in the installation of the electrode.

Stationary copper-sulfate electrodes SMES Mendeleevets have stable value of their own potential in different conditions of environment.
