Chell Instruments has developed
its wheel measurement system into a fully digital onboard
design. This coupled with the use of slip
rings leads to a highly functional, low weight
system.
The system will measure 32 or 64 pressures
anywhere on a rotating wheel. These pressure
can be averaged over any number of
revolutions. Once the average is complete, the
data is down loaded to a PC via Ethernet where
the pressure profile of the wheel can be plotted
and the corresponding life and drag calculated.
The WSMSD system is designed on a series of
flexible PCB’s. This removes the mass and
inconvenience of cabling inside the wheel. The
main PCB performs all the acquisition tasks and
stores the data. The system usually consists of
two or three addition flexible PCB’s that make all
the connections to the transducers.
The system can be delivered calibrated with either
32 or 64 channels using miniature surface mount
transducers.
