Autonomous Long-Term Monitoring of measurands

System Overview

TEDIASENS systems are used for wireless measuring data transmission and data logging for industrial and geostationary applications. In addition to the TEDIASENS systems type SN-I and SN-X, used for synchronous data logging typically for short measurement times with online evaluation, there are now LOGGING NODE systems available for long-term monitoring with radio connection.

LOGGING NODE measurement systems are used for different measures depending on the type of internal and external sensors. The measured data can be monitored and recorded continuously or periodically over a period of several years. Selected measured data, alarms and preprocessed signals are transmitted to the gateway via radio which provides the data within the network.

Compared to other measurement systems LOGGING NODES provides the following advantages:

  • Easy Installation
  • Connection via radio
  • Power supply with battery possible
  • No or low cabling effort
  • Operation without gateway possible

Application Areas

LOGGING NODE systems are used wherever measures have to be monitored in the long-term.

Machine Monitoring

LOGGING NODES allow an easy long-term condition monitoring of existing machines with minimal intervention. Thus, maintenance can be planned better and unexpected failures can be avoided. LOGGING NODES are used for example in manufacturing or energy production. LOGGING NODE systems measure vibration and other dynamic parameters of machines periodically or continuously over a long time period. Based on this characteristic signals are calculated to provide information about the machine state over time.

Monitoring of Structures

LOGGING NODE systems are used in different application areas for monitoring structures:

  • Measurement of vibrations
  • Detection of changes in the building structure
  • Detection of critical Situations

LOGGING NODES are operated fully independently and without external power supply. The sensors are monitored continuously. In the case of exceeding user defined threshold values, measurement values will be stored and alarms can be triggered.
