During the last few months we improved the hardware of our heartpiece, the iBWIM Spider.
Instead of 16bit, we now use 32bit-technology for strain gauge measurement, which upgraded the accuracy of the whole system.
The µC-firmware was completely renewed and aligned to the new hardware and is more efficient than ever.
The new iBWIM Spider in generation four also has two additional channels for sensors with mA-outputs such as laser sensors, which we already use in our system.
Due to the laser sensors it is possible to count axles of vehicles more efficiently, especially at railway bridges but it is also possible to make simple traffic countings.
The new ADC-technology we used improves the accuracy and efficiency of all our sensors.
In addition to the new hardware we also developed a WLAN version of the Spider, which is supplied via batteries. Hereby it is possible to undertake short term measurements, traffic counting and control measurements. The data is sent to a router or a computer via WLAN what simplifies the installation considerable.
