Radio-based IIoT condition monitoring: easy retrofitting of machines and systems

Date: Wednesday, 7 May 2025
Location: Hall 2 | Time: 11:30 - 12:00
Speaker: Stefan Kunisch

Existing systems often lack integrated monitoring tools, which makes predictive maintenance more difficult. According to TÜV Rheinland, 30-35% of damage could be avoided with a condition monitoring system. Measurement specialist Althen offers a retrofittable, wireless monitoring system for rotating plant components. Sensors send vibration data wirelessly to a gateway and on to the cloud. The Althen software enables detailed analyses from threshold value triggers to FFT diagnostics. Users can create individual dashboards and visualise production lines. The presentation will cover the use of sensors, installation and functions of the Althen IoT Monitor.

Geotechnical measurements

Geotechnical inclinometers are precise measuring devices that are used to monitor ground movements and deformations in buildings and geostructures. They are used to recognise potential dangers such as landslides, foundation failure or subsidence at an early stage. In safety monitoring, they identify movements that could jeopardise buildings or people. The sensors can be used to support construction planning and the validation of ground stability models. They are also suitable for long-term monitoring, e.g. to check soil behaviour after the completion of construction projects (such as in mining or dams).

Increased earth pressure can indicate an unstable soil structure or impending ground movements that could lead to landslides, landslides or other dangerous situations. By continuously monitoring this pressure, potential risks can be recognised at an early stage so that protective measures can be taken in good time to prevent damage and accidents. Model tests are often carried out before the start of construction projects. Althen offers various ground pressure sensors from TML for this purpose.

Condition Monitoring

Strain gauges for condition monitoring are specially developed sensors that are used to measure deformations and stresses in concrete structures or synthetic resin. Among other things, these sensors measure the stress and temperature of the material during curing (internal strain measurement) as well as the behaviour of cracks in the surfaces of the materials. They are required for roads, bridges, retaining walls, struts and sheet piling.

The wireless vibration monitoring system from Althen makes it easy to retrofit rotating machinery such as motors, pumps and compressors - without any additional hardware. The system comprises battery-powered, wireless industrial sensors and a gateway that securely transmits the recorded data to the cloud. A flexible dashboard is available for analysis and visualisation, which can be tailored to your specific requirements.

Magnetostrictive linear position sensors

Our magnetostrictive linear position sensors offer a precise and reliable way to monitor the position of moving parts in various applications. They measure according to the magnetostrictive principle and - due to the non-contact measuring method - are suitable for environments in which dust, dirt or vibrations can impair an accurate measurement. They are used wherever high accuracy and long-term stability are required.
