Description

The ESMS-M2-VE model is an installation for monitoring the condition of underground metal objects. It should be ordered when accurate control of corrosion changes of pipelines and other steel structures is required. The modernized copper sulfate reference electrodes are equipped with an auxiliary electrode and have two membranes.

The operating principle consists in installing the device directly in the soil. The depth must correspond to the laying level of the object under inspection and must not be above the soil freezing depth. The conductors of the unit can be used as portable, and routed to a cover or to KIP.

Double-membrane modernized copper sulfate reference electrodes with auxiliary electrodes have the following advantages:

• bentonite chamber;
• fully sealed housing;
• durable construction material;
• the unit is ready for use;
• cable length can be specified by the customer.

When working with the reference electrodes, no preparation or electrolyte filling is required. The device housing is capable of withstanding impacts and other moderate mechanical damage. When purchasing reference electrodes, the customer can independently choose the required cable length. The final order price depends on this parameter.

Technical features

Several modifications of reference electrodes are available. In addition to the basic version, the manufacturer offers the ESMS-VE-M model. This device is supplemented with an auxiliary electrode. The housing is filled with copper sulfate, with a pure copper electrode inside. Contact with the soil surface is maintained by an ion-exchange membrane located in the lower part. The auxiliary electrode is located on the side of the reference electrode housing.

Each cable has tags with information and lugs for connection to KIP. This makes installation, operation, and maintenance of the unit convenient and clear.

The device is intended for control measurements on underground metal structures, including pipelines and other constructions. Modernized copper sulfate reference electrodes with an auxiliary electrode make it possible to determine the degree of protection of the facility against corrosion.

The method of operation of the electrodes consists in installing the device below the soil freezing depth. The measurements are based on oxidation and reduction reactions. The design provides for bringing the conductors directly to a cover or to KIP. The modernized reference electrodes are non-polarizable and have a long service life.

Advantages:

1. The model can be ordered with a specified length of connecting cables.
2. The device is fully ready for use. There is no need to fill electrolyte or perform other preparatory operations.
3. The outer housing is made of durable and sealed material. It withstands impacts and mechanical damage.

5. The porosity of the capillary channels of the outer ceramic membrane is standardized. This ensures good electrolytic contact with the soil at the measurement point.

Technical features

Two modification types of reference electrodes are available. Their difference lies in the auxiliary electrode, which is present in the ESMC-M-VE model. The ESMC device does not have such an electrode. Inside the housing of the additional element there is copper sulfate. A spiral-shaped copper electrode made of refined copper is located in it.

During operation of the device, the preservation of the electrolyte volume in the housing is ensured by an ion membrane. With its help, electrolytic contact of the mass with the electrode is constantly maintained. The material of the contact mass is bentonite clay. Its purpose in the device is to ensure contact with the soil under conditions of low moisture. A porous diaphragm located in the lower part of the device housing serves to provide contact between the soil and the mass.

The auxiliary electrode makes it possible to measure the polarization potential in a pipeline. It is present in the ESMC-M-VE modification model. The equipment is supplied with cable outlets already installed, which have marking tags. This significantly simplifies maintenance of the modernized copper sulfate reference electrodes with an auxiliary electrode. The minimum length of the outlet cables is 5 meters and can be increased at the request of the customer.

One of the important advantages of these ES devices is the stable values of their own potential. Due to this, the measurements are максимально accurate. The minimum operating temperature is -5 °C, the maximum is +45 °C.

Copper sulfate reference electrodes have a special container for installation. Its housing consists of:

• PVC pipe;
• sealed cover;
• sealed cover;
• sealing ring;
• cable outlets.

The PVC container is intended for installation and removal of the device from the soil surface. The material is sufficiently strong and does not deform during operation. A special terminal plate is located on the housing, to which the electrode leads are connected. They are connected using terminals.

The cable outlet points are hermetically sealed. The standard length of the installation container is 220 cm. The customer can change this parameter when placing an order. The price will depend on the selected length. The diameter has a constant value of 16 cm.

To establish contact of the electrode with the soil surface, the container has perforations at the bottom of the device. The upper part of the installation container is closed and completely sealed.

Technical parameters:

• copper electrode;
• gel-like saturated solution of copper(II) sulfate pentahydrate according to GOST 19347;
• ion-exchange polymer membrane;
• inner housing;
• contact unit (ion-exchange ceramic membrane);
• contact electrolytic mass or its gel-like solution;
• housing;
• auxiliary electrode;
• cable outlet with cable.

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.

KMG-MES-01-(K)-T-VE-M are installed directly in the soil at the level of the lower generatrix of the protected structure, at a distance of no more than 0.1 m. The installation depth is selected according to the location of the underground metal structure. It is important that KMG-MES-01-(K)-T-VE-M is located below the soil freezing depth. The cables are equipped with terminals for connection to the terminal panel in KIP or in a cover.

Equipped with an auxiliary electrode made of carbon steel with a contact area of at least 625 mm2. They can also be used as portable units.

Advantages

The product is supplied fully factory-ready for operation, i.e., it does not require prolonged pre-soaking before installation in the soil to activate the electrolytic junction.

The housing of KMG-MES-01-(K)-T-VE-M is made of impact-resistant frost-resistant material and is completely sealed.

Electrolytic contact with the soil is formed through capillary channels of the external ceramic membrane with standardized porosity.

The length of the cables of the reference electrode and the auxiliary electrode is not fixed and is specified by the customer.

The presence of an additional chamber (double-membrane reference electrodes) eliminates mutual diffusion of the electrode electrolyte and soil electrolyte by using a solid-state electrolyte based on bentonite.
