iBWIM Spider is a data collection unit for iBWIM measurement. Several spiders can be connected and powered by a local network. They are precisely synchronised and provide a maximum of 128 channels.
One spider typically manages eight strain gauge sensors and one temperature sensor. The actual version offers two current channels optionally used by laser or ultrasonic sensors.
Data is collected with 32bit ADC technology, enabling the measurement of very small changes in strains. The unit offers sampling rates ranging from 500Hz to 1,400Hz. Notice is reduced due to very high internal sampling and according averaging.
Every Spider transmits data packages over LAN to a router / server component, where they are treated and combined to data records for each truck event.
