The device is designed for underground work. All measurements are performed on structures located below ground level. ECS must be installed above the underground object and placed below the soil freezing level. For measurements in soft soils, the package includes a tip. ECSM-P-VE for hard soils should be ordered with a plug-type tip.

Inside the housing, there is a copper electrode. It is placed in copper sulfate. The measuring element itself is fixed on an aluminum tube. For convenient handling, the tube has a rubberized layer. The electrode cable is led to a terminal. Two types of ECS are available for sale:

• ECS-1.2 – designed for intensive work and equipped with a full-size handle;
• ECS-0.4 – has a shortened handle and is used as a stationary measuring device.

ECSM-P-VE is additionally equipped with an auxiliary electrode (VE). The VE is made of steel in the form of a ring. The additional electrode is located on the side of the unit housing. The price of ECSM-P-VE depends on the selected model and additional components.

Each ECS wire has terminals for connection and labeling plates. This significantly simplifies operation and maintenance of the device. Copper sulfate electrodes can be used at temperatures from -5°C to +45°C.

Technical Specifications

For the models, the cup diameter is 18 mm on the inner edge and 25 mm on the outer edge. The cable length indicated is standard and can be increased in agreement with the customer. Delivery and package contents of ECSM-P-VE are discussed separately.

ECS are used to monitor the condition of pipelines and other metallic structures located below ground level. ECSM-P can be ordered to assess the cathodic protection of pipelines for various purposes. The ECS can be equipped with an auxiliary electrode (VE), and the electrode contact part is made of different materials.

The allowable air temperature for using ECS is minimum 0°C, maximum +50°C. At 100% humidity, the ambient temperature should be approximately +35°C. The design of the ECS depends on the modification and can be supplemented with an installation container.

The price of ECSM-P depends on the selected wire length. This parameter is coordinated with the customer. Installation of portable ECS is performed above the metallic object. For accurate data, the electrode must be placed below the soil freezing level.

Technical Specifications

Delivery of ECSM-P is fully coordinated with the customer. The package includes a user manual. The number of electrodes is determined by the order.

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.
