Reference electrodes play a key role in cathodic protection systems designed to prevent corrosion of underground steel pipelines and structures.

Their application is based on the ability to measure polarization and total potentials, which makes it possible to effectively monitor and maintain optimal conditions of electrochemical interaction.

PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode provide accurate potential data on corrosion-prone facilities (oil and gas pipelines), which is critical for assessing the effectiveness of the protection system.

Regular monitoring of polarization potential helps prevent undesirable electrochemical reactions, contributing to the preservation of the integrity of steel pipeline lines and underground facilities.

Reference electrodes are an integral part of infrastructure. Their use helps extend service life and increase the efficiency and reliability of transport systems and structures under underground operating conditions.

Our company offers PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode, non-polarizable and long-life, specifically designed for use in soil at depths exceeding the soil freezing level. The conductors can be routed to a cover or to a test point (KIP).

Advantages

PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode are ready for use and do not require additional preparation or electrolyte filling.

The reference electrode is placed in a durable container made of material resistant to mechanical damage.

Efficiency is achieved through capillary channels of the outer ceramic membrane with standardized porosity, through which electrolytic contact is formed. This ensures stable operation over a long period.

The cable length is not regulated and can be any. The customer determines the required cable length for the facility.

The advantage of using a bentonite chamber in PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode is the prevention of mutual diffusion of electrolyte between the electrode and the soil. This ensures stability and efficiency over long-term operation.

One of the important parameters is spreading resistance, which is at least 5 kΩ.

The potential relative to a laboratory silver/silver chloride reference electrode is 100±20 mV, indicating the accuracy and reliability of measurements performed using this system.

The devices operate for up to 30 years or more.

The weight of the device, excluding cable outlets, does not exceed 2.5 kg, which makes it convenient and cost-effective for transportation and installation.

MES-02-(P-K)-T-VE are installed in soil below the freezing depth in accordance with the depth of the metal structure. The conductors are routed to a cover or to KIP and can be used as portable.

MES-02-(P-K)-T-VE stationary copper sulfate reference electrodes with an auxiliary electrode have a stable potential over a long period of time. The non-polarizable electrochemical system does not change its potential when a small current flows through it. This makes it possible to obtain accurate and reliable results in tests and measurements.

Reference electrodes can be used in different soil types (arid, saline, etc.). The measuring cable in the device is load-bearing and is used for installation of the electrode.

The MES-02-(P-K)-G-VE model has its own features – it is a double-housing device. The outer ceramic housing is intended to create and maintain electrolytic contact during measurements. The porous ceramic is sufficiently strong and capable of withstanding moderate mechanical воздействия. Inside it there is a measuring module. This is the second housing filled with copper sulfate. The reference electrode is located in it. The space between the housings is filled with a moisture-retaining substance.

To measure the polarization potential, the device is equipped with an auxiliary electrode. The VE is located in the lower part of the housing and is connected to terminals. Marked cables are routed from the main and auxiliary electrodes. The information tags are intended for more convenient operation and maintenance of the reference electrodes. Stationary copper sulfate reference electrodes with an auxiliary electrode (VE) can be ordered for performing measurements in arid regions.

Technical description

To ensure a stable electrolytic junction between the reference electrode and the soil electrolyte at the level of the lowest resistance required when performing specific measurements of protective potential values, an ion-exchange ceramic membrane with standardized porosity is used in the long-life reference electrode. The internal cavity of the outer housing is filled with a contact electrolytic mass based on bentonite clay. The inner housing of KMG-MES-02-(P-K)-(G-T)-VE-M is filled with a gel-like saturated copper solution in which the electrode is located in the form of a spiral made of pure refined copper.

Under certain soil conditions, such as increased soil resistivity, the so-called “arid soils”, the KMG-MES-02-(P-K)-(G-T)-VE-M reference electrode gains higher stability and durability due to the fact that the outer housing is filled with a special moisture-retaining electrolytic mass based on bentonite.

To ensure convenient installation and subsequent operation of the products, the cables of the reference electrode and the auxiliary electrode are equipped with cable lugs for connection to KIP.
