Find out what the TELCORR 4 module has to offer

TELCORR 4 is a state-of-the-art telemetry module designed for the application in corrosion protection systems for pipelines and other underground steel structures. The device enables the control and monitoring of cathodic protection stations that do not have their own measurement and communication systems, as well as the performance of advanced measurements and management functions. By using TELCORR 4, you also gain:

The ability to measure protective potentials at measuring posts and to measure monoblocks and drainage systems

Remote configuration, reading of results and full control over the device’s operation, including monitoring for a failure in the power supply

The recording and accumulation of measurements, together with their preliminary processing

Time synchronisation with the GPS system

High operational reliability across a wide range of temperatures and environmental conditions

Applications

Cathodic protection systems for pipelines

TELCORR 4 is ideal for use in pipeline cathodic protection systems, enabling remote monitoring of protection parameters, circuit control and integration with higher-level monitoring systems.

Underground steel structures

The device can be used to monitor and manage the corrosion protection of tanks, industrial installations and other underground steel structures requiring precise measurements and reliable communication.

Cathodic protection stations without their own telemetry

Thanks to its extensive communication capabilities, TELCORR 4 enables the expansion of existing cathodic protection stations with measurement, telemetry and control functions.

Integrate measurement and control in a single device

TELCORR 4 is a compact and modular telemetry solution that can be mounted on a DIN rail in measurement posts. Support for multiple power supplies, including an external high-capacity battery, enables many years of autonomous operation in the field.

Advanced digital signal processing, correlation measurements and the ability to perform tasks according to a schedule make TELCORR 4 a key component of an integrated cathodic protection system, working in conjunction with MSOK 2 devices and the CSMOK IT system.
