pliance
systems offer the state of the art technology
for pressure distribution measurement
between soft and curved surfaces. The
systems consist of a flexible and elastic
measuring mat, a multi-channel analyser,
a calibration device and a software package
for PC's.
As in all physical measuring systems the
most important part is the sensor technology.
pliance works with capacitive transducers
in a matrix configuration. The elasticity
of the sensor mats permits perfect comformability
to 3-dimensional deformations.
The pressure transducing elements contain
high-tech elastomers manufactured by novel.
Restoring force, range of force, threshold,
hysteresis, temperature effect, frequency
response and other characteristics are
determined during the manufacturing process.
This makes it possible to adapt the sensor
characteristic to different measuring
needs. The elastic measuring mats are
available in various sizes, sensor configurations
and pressure ranges.
The pliance analysers vary from small
portable 16x16 channel units to large
112x112 channel units with a wide range
of options, such as master-slave synchronisation
of several systems, dynamic amplification
control, synchronisation of video systems
and analog inputs for accelerometors.
novel developed an analyser technology
that allows not only individual calibration
curves for each sensor, but also individual
dynamic amplification control and crosstalk
suppression, resulting in very accurate
and reproducible pressure values. The
pliance analysis can work with PC's via
the USB interface. Notebook computers
or even pocket PC´s can be used
for mobile tests.
The trublu calibration device can be used
at any time to verify the quality of the
measuring results. It works with homogeneous
air pressure on all sensors through increasing
steps of pressure. Thus an individual
calibration curve for each sensor is calculated
and used during data aquisition.
The software operates as a Windows application
and contains many useful methods of data
collection and scientific analysis of
dynamic pressure distrubution. It also
allows continuous data storage in online
mode and data handling with a configurable
SQL database. The expert can design the
parameter configuration to specific needs
and exchange data with collegues via HTML
protocol.
