Crack Displacement Sensor

We supply hi-tech crack displacement sensor to our esteemed clients. The crack displacement sensor analyzes the crack displacements, change of length as well as relative / absolute humidity and air temperature. The crack displacement sensor offered by us is entirely based on high-resolution crack analysis sensor system and the revolutionary digital cmosens® technology. In crack displacement sensor, small shock-resistant and watertight housing combine a high resolution 12-bit crack analysis electronic. Avail the crack displacement sensor from us at market leading prices. about crack displacement sensor :

• it consists of 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 characterized by especially easy handling, small dimensions, high reliability as well as high precision.
• after the fast and 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. For this purpose the system analyses the crack approximately 100 times per second and registers the external values.
• together with the climate sensors, comprehensive and meaningful measuring data are available after a short while.
• the fully calibrated intelligent cmosens® sensor for temperature and humidity is characterized in particular by its optimized 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 universal softfox software under microsoft windows 98, nt, me, 2000, xp or vista.
• after connecting the rissfox mini to the computer via a usb or serial interface cable, the system can be read out or configured immediately.
• the software offers numerous general functions like the dynamic project management, graphical data analysis, computer controlled series of measurements, dew point calculation, export functions, automatic backup, flexible zoom, and much more. Furthermore, the data logger itself can be programmed according to the needs of the user.
• for this purpose many software functions are available e.g. Setting the measurement rhythm (1 second up to 24 hours), fully automatic start-stop-operation or ring buffered data acquisition, alarm conditions for sms alarm notification, acoustic alarm or telephone alarm, min/max-detection for a consistent registration of external values, setting the system clock, precise battery test, digital serial number and much more.
• in addition to the data evaluation with the computer, it is possible to connect a flexible alarm system to the data logger.
• by this means e.g. A sms notification can be transmitted when the crack displacement exceeds a predefined value.
• it is also possible to trigger a telephone alarm, when the air temperature or humidity falls/rises below/above a specified threshold. An acoustic alarm buzzer is also available.
• the fields of application for 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.

• data memory for 16000 readings integrated (optional data memory for up to 64000 readings)
• measuring and storing rhythm (1 second to 24 hours) freely adjustable via pc software
• freely programmable fully automatic start-stop-operation or endless loop storage
• crystal oscillator controlled real-time clock and real-time calendar integrated
• measuring range of the crack sensor : 10 mm (+/- 5mm)
• extended measuring range of the crack sensor e.g. 75mm available as customized version
• resolution of the crack sensor : 2.5µm = 0.0025mm = 0.0001inch
• length of the crack sensor cable : 2m (longer sensor cable up to 100m available on request)
• high-speed crack monitoring with up to 100 hz can be activated
• no mechanical torsion of the sensor, thanks to the complete decoupling of the stopper
• sensor zeroing (tara function) and system start via activation magnet
• optional: combined air temperature and humidity sensor (climate sensors) available
• no calibration of the climate sensors necessary
• measuring range of the air temperature sensor : - 20oc to 70oc
• measuring range of the humidity sensor : 0 %rh to 100 %rh (dew free)
• resolution of both climate sensors : 0.1 oc / 0.1 %rh
• measuring accuracy of the air temperature sensor :
