fischer launches a world first in construction monitoring

Intelligent safety monitoring

fischer is the world’s first company in fastening technology to offer an intelligent and integrated monitoring solution for constructions and facilities. The solution increases the overall flow of information, service life, sustainability and safety of constructions and facilities while ensuring higher maintenance efficiency.

The sensor-integrated fixing products SensorAnchor and SensorDisc provide users with a time and resource-saving method to identify current acting forces in fastenings. The products transfer the wireless data to the Construction Monitoring module of the myfischer portal, allowing the information to be accessed via web applications on a tablet, PC or laptop or on a smartphone with the construction site-friendly fischer PRO ap.

Secure connections, intelligent interconnection Thanks to intelligent force monitoring of fastenings, threshold violations and problems can be identified early on in order to take measures, significantly increasing the level of safety. The flow of information reduces the level of complexity, increasing the efficiency of maintaining constructions and facilities. Maintenance intervals are either extended or avoided entirely. The service life of constructions and facilities is extended, which simultaneously increases sustainability.

SensorAnchor: Monitor forces from a distance A secure anchorage must be guaranteed for countless applications, including rollercoaster support legs, scaffolds and other steel structures, industrial robots anchored to the floor or suspended ventilation systems and other installations in tunnel construction. Additional applications include noise barriers, climbing formwork on high-rise constructions, seismic bracing, high-voltage power line fixings and much more. fischer’s new SensorAnchor enables the permanent and intelligent monitoring of the absolute values of a fixing’s preload and operational forces.

The product consists of an anchor rod with an integrated sensor that allows forces to be measured directly in the fastening (flux). In order to read the measured values, the SensorAnchor is continuously connected to the battery or mains-powered SensorGateway, which transfers the encrypted data to the fischer cloud in a defined cycle through a wireless standard developed specifically for the Internet of Things (NB-IoT).

Preload and operational forces are continuously monitored in real time and sent to the Construction Monitoring software application. In order to read the current measurement, the SensorGateway that requires checking is simply accessed via the app before the connected anchor is selected. If the defined force exceeds or falls below the threshold values, a push notification is immediately sent to the smartphone or browser.

The SensorAnchor is made of highly corrosion-resistant stainless steel and is available in all sizes of M16 and above. Up to four anchors can be monitored per gateway. IP67 protection for the electronics in addition to the shock and impact-resistant Gateway housing provide additional safety during construction and industrial applications.

SensorDisc: Scan forces with a smartphone In addition to the SensorAnchor, fischer is also launching its SensorDisc, a washer for the long-term monitoring of preload force levels of standard screw connections. The measurement is provided at the time of the reading. In order to enable monitoring, the product made of highly corrosion-resistant stainless steel is equipped with a measurement and readout sensor as well as an antenna. No additional hardware is required. The measured value is the preload level percentage in relation to the installation state.

Data is transferred using contactless technology and can be accessed via the fischer PRO app using a standard smartphone. The SensorDisc can be used for years thanks to its battery-free, fully passive electronics. Energy is generated via the electric field produced by the reading device and is used to supply the system. If the SensorDisc is touched with a smartphone, this transfers the energy field to the disc, which is then used to measure the current force in the screw connection and report the measured value back to the mobile device. In order to see the remaining percentage of the original preload force, the SensorDisc simply has to be selected and scanned using the PRO app. The disc only needs to be tapped with a standard smartphone to be scanned and can be repeatedly loosened, disassembled and reused in another location.

The washer is available in sizes M16 and above with no upper limit. SensorDisc applications include wind turbines, crane runways, concrete formwork and flange joints on pipe systems, such as on process engineering or petrochemical production plants.
