Welcome to the website of Kühnicke Embedded Real Time (KERT)

Our goal is the research, development and application of sensors with embedded measuring systems for fast acquisition and analysis of data. All sensors have a network connection, either wireless or via Single Pair Ethernet cable. Power is supplied to the wireless variants via lithium-ion accumulators. The Single Pair cable is used in the Ethernet version for data transmission and power supply. das Ethernetkabel (Power over Ethernet, PoE). The measuring systems work according to the client-server principle. The sensor is the server and generates dynamic web pages. The client can be any computer (desktop, notebook, tablet or smartphone) on the network. This means that every standard browser on a client computer controls the sensor and displays the measurement results.

1G.WiFi.80kHz -- since 2016
AE sensor of 1st generation
with integrated measuring system
3G.WiFi.200kHz -- since 2020
AE sensor of 3rd generation
with integrated measuring system

Sensors with an integrated measuring system have been developed for the non-destructive testing method acoustic emission since 2016. The fourth generation of these sensors is now being tested.

The sensor housing contains an analog section, a digital signal processing unit and a web server. The analogue part amplifies the sensor signal and forms the logarithmic envelop for data reduction. AE parameters such as arrival time, rise time, duration, peak amplitude and energy are extracted from the envelope by the digital signal processing unit. In parallel to the parameter extraction, the waveform of the envelope can be recorded. The web server generates dynamic web pages to control the sensor and to display the measurement results. These results are available anywhere on the network and can be viewed with any browser. Even at low data transmission rates, a high temporal resolution of the diagrams is achieved. The fourth generation sensors have time synchronization accurate to the microsecond. This enables the AE sources to be located. The server-client principle enables the construction of low-priced acoustic emission systems. The web structure takes care of high flexibility.

Our service advises and assists you in the selection and adaptation of hardware and software as well as in the design of the network architecture and the possibilities for self-sufficient power supply. For other applications we develop sensors in your order. Our experience is relevant for measurement tasks where the data rate is high and which require intelligent information compression.
