Our solution consists of a complete package of hardware and software which is shipped in a hard product shell case. It consists of state-of the art smartphones (Samsung for non-Ex and i.safe MOBILE for Ex), a measuring technology, state-of-the-art acoustic emission sensors, a waveguide for hot and cold surfaces, our Senseven app for internal leak detection in valves and access to our backoffice solution for structured storage of all measurement data, automated reporting and further analysis.

Acoustic Emission Testing (AET), is a non-destructive test technique, detects high-frequency stress waves emitted by changes in materials or structures under load. These waves can additionally also be detected on structures or components where a leak flow as a result of pressure differences appears and generates acoustic emission. It allows the detection of discontinuity and its progress, even before the defect/fault occurs.

Our delivery includes the robust smartphone Samsung Galaxy XCover Pro for Valve Sense in industrial applications. For international Ex-Zones we use the modern 5G smartphone IS 540.1 from i.safe MOBILE. Both phones have the necessary power to process the amount of data and the measuring systems are also adapted to the smartphones.

The system can be used for all on/off, control and safety valves of any size. However, in the case of larger valves (above DN 100), several measurements must be carried out on the valve body and small leaks may be harder to find.

The system is optimized for the media water, gas, steam and pressurized air. For
other media such as viscous liquids, it also works, but the smallest detectable leak
size can be larger than for other media.

The measurement software is available for smartphones, however with the Senseven Backoffice you will get access to all measurements from any device for reporting and analysis purposes.

After purchasing the product, you will receive an introduction to the operation of the product. We are happy to issue you with a certificate of participation.

Yes indeed. High pressure is even advantageous for Valve Sense. The higher the
pressure, the stronger the acoustic emission signal which is created by the leak.
We require a minimum of 1 bar pressure differential in order to detect acoustic
emission signals.

You must ensure that the valve is closed and that there is a pressure differential before and after the valve. Before starting the measurement, the medium must be selected. Additional information is optional.
