For measuring and logging changes in crack width in the Range ± 5 mm with a resolution of 5µm. Climate log with built in temperature and humidity sensors as optional extra.

A small, impact resistant and waterproof casing contains an enormously powerful analysis system, comprising an electronic hi-resolution 12-bit crack analysis, a RISC-microcontroller, memory up to 64,000 sets of measurement, and a quartz real time unit.

The integrated Hi-Speed Crack-Monitoring facilitates secure and precise recognition of even extremely short oscillations.

Battery operated for Up to 2 Years operation with one set of Bateries (2 x AA).  All data in the memory remain securely stored, even in zero Volt condition. 

Rissfox Mini 11

After installation of the sensor across the crack (simply glued to the building with the hi-bond adhesive included in the supply), the system automatically starts the logging process previously programmed via note book. Alternatively, it may be activated by no touch solenoid. The data logger records  the measurement data at previously selected frequency. 

The inclusion of climate sensors facilitates the recording of changes in the crack, caused by climatic influences. Therefore it offers the identification of changes in crack width due to:


  • mechanical
  • thermal and
  • humidity

A powerful addition, with four additional incoming Sensor-Terminals and flexible outgoing Alarm facility, for direct Connection to the RISSFOX Base Unit.

The Alarm facility covers all Sensors connecting into this unit and can be easily set at individually suited configuration. By specifying Crucial Parameters, like exceeding a pre-set Value of Movement, or a pre-determined Alarm-Threshold, the stored addresses of the receipients will immediately notified. The Alarm-Mode can also be configured for delayed activation, so that the Alarm is raised only, once a notifyable condition has occurred and prevailed for a pre-set period of time. For the actual transmission of an alarm, as well as data transfer, the RF Module is required.

For wireless bi-directional Transmission of Data and Alarm Impulses, mobile and fully automatically, world wide, via e-mail or Text.

This RF-Module represents an enormously powerful Remote-Data-Transmission System for mobile wireless Data Communication world wide. It accommodates 2 Data Logger Units inclusive of their subsidiary attachments. All Measuring Data stored will be transferred automatically per e-mail at regular intervals. Where ever you are, you can evaluate the Data on your computer, exactly as if you were present at the measuring site. If interim data are required urgently, just dial the RF-Module and you will receive all information instantly

Two Alarm-In Terminals facilitate the flexible notification via e-mail or Text. The complete System is mains-independent and receives the power required from standard AAA-Batteries. One Set of Batteries is sufficient to send hundreds of e-mails within one year (dependant upon Memory Capacity of the Data-Logger). A mains Adapter is also available as optional extra. In the event of a power failure, or low battery level, the unit will send a notification. Simple and comfortable Configuration of the RF-Unit by means of the Analysis Software on your PC.
