POTENTIAL DROP MEASURING SYSTEMS FOR INDUSTRY AND RESEARCH
The Limit measuring system was developed by Sobriety to monitor the service life of materials used in pipelines and steam piping in power facilities. The Limit unit is based on the potential drop technique. The specific advantages of this method of analysis are the ability to detect and monitor the actual status of the target device, during runtime, without dismantling and by a completely non-destructive method.
AREAS OF APPLICATION
Potential drop technique measurement can be used, for example, in the chemical, energy, aerospace and construction industries.
Measured components can be exposed to extreme temperatures, pressure or radioactivity. They can be placed in ovens and autoclaves, strong electromagnetic fields, chemically aggressive or wet environments.
The resulting technical diagnostics are applicable in industrial operations and during stress and fatigue tests. It is possible to measure deformations, material thickness, and the influence of corrosive wear, and to detect and analyse cracks and their parameters.
Limit is the product successor of the Poteron PD05, which has been a proven electric potential drop technique based measuring system for technical analysis in extreme environments for many years. Limit has been designed for maximum reliability and accuracy in permanent installations, for example in steam pipelines and power plant pipelines or other demanding operations.
The measuring device offers ACPD measurement and corrected DCPD measurement. Limit is characterised by high accuracy, stability and resolution. The ATEX certified Limit is intended for use in a potentially explosive atmosphere. The measuring unit is dustproof and waterproof according to the IP65 standard. The connectivity is defined by Bluetooth and RS-422 communication standards.
The system control is provided by the Limit Control software developed by us. It enables online and offline measurement, calibration, analysis of measured data, and simulation of specific conditions. The user interface is intuitive, easy to use, and clear even on a smaller computer display.
The standard product package includes, in addition to the measuring device itself, a power supply or battery, data management and evaluation software, user manual, communication protocol, cabling and a transport case.
The Limit measuring system is designed for laboratory material testing. Measurement of the electric potential drop effectively indicates the deformation initiation and crack growth in the measured specimen. This methodology offers an effective way of eliminating the influence of other physical effects on measurement accuracy and provides a conclusive analysis under simulated conditions of radiation and extreme pressure and temperature.
Systems for Technical Diagnostics
Limit allows for monitoring inaccessible equipment during full operation and detection of any defects that could endanger the functionality of the equipment or pose significant risks to its life and operating capacity. In industrial practice, Limit is used to check the actual status of pipelines, columns, steam piping or welds. For example, the possible development of cracks or material loss in pipelines is monitored.
Special accessories enable the optimisation of the measuring system for specific application requirements. Accessories include various electrodes for measuring unit installation, electrode welding units, electrode positioning tools and special tools for easy and fast electrode installation.
