Analysis of crack displacements and climate data


Fully automatic recording of thanks to the high-resolution and the revolutionary digital technology! crack displacements, air temperature and humidity crack analysis sensor system CMOSens®

With the Rissfox Mini, you get one of the most advanced miniature data loggers of our time. In its shock-resistant and watertight housing it combines , an air temperature sensor and air humidity sensor, a RISC microcontroller, memory for up to 64000 measuring values and a real-time clock into an enormously powerful analysis system.

The fully calibrated crack sensor which can be connected to the system is characterised by especially easy handling, small dimensions and high precision. After the easy installation of the analysis sensor over the crack, the measuring system either starts automatically the measuring task previously programmed on the PC or is activated without contact via a magnetic switch. The data logger then records the measuring data at a freely adjustable rhythm.

The integrated high-speed crack monitoring allows reliable and precise detection of even shortest crack vibrations. Together with the climate sensors, comprehensive and meaningful measuring data are available after a short while. The fully calibrated intelligent sensor for temperature and humidity is characterised in particular by its optimised long-time stability, high precision, reliability and extremely fast response time of less than 3 seconds. Laborious re-calibration is not necessary, because the sensor can simply be replaced directly on site if need be. The batteries (AA) integrated in the data logger supply the system with power for up to two years and can be replaced easily at any time.

® The data logger is programmed and evaluated with the under Microsoft Windows 98, NT, Me, 2000 or XP. After connecting the Rissfox Mini to the computer via a PC interface cable, the system can be read out or configured immediately

The fields of application of the Rissfox Mini are almost unlimited and range from building monitoring and damage assessment to structural condition analysis and monument protection to preventive maintenance, research and development etc.
