DIGITAL CRACKMONITOR Crackfox Mini
|
For measuring and logging changes in crack width in the Range ± 5 mm with a resolution of 2,5µm. 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.

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 induced influences

EXTENSION MODULE
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.
