| CT4/8-Wheel
is an telemetry
system designed
for easy mounting
onto rotating
Wheels to provide
non-contact
transmission of
measured
parameters such as
pressure, force,
temperature,
acceleration and
voltage.
Sensors
inputs are
connected via
screw on,
waterproof
connectors.
Measured values
are prepared in
analog format,
digitized and
transmitted via
radio frequencies.
Four different
carrier
frequencies are
provided, this
allows up to four
systems (e.g. for
four wheels) to
operate in
parallel. The
complete
transmitter
assembly is
waterproofed to
IP65
specifications.
The
following sensors
can be connected
to the system: (STG)
Strain gages
sensors in full-,
half- and
quarter-bridge
configuration (350
ohm or greater),
Type K
Thermocouples to
1000°C, ICP and
capacitive sensors.
Voltage inputs of
+/-5V and +/-10V
are available.
The
measured values
are processed and
output as +/-5V
analog signals at
the BNC sockets (optional
digital output for
special PCM
interface into a
PC) on the
stationary
receiver located
in a vehicle or
helicopter cabin.
Resolution
of 12 bits is
standard; this
enables an
amplitude dynamic
of 72 dB. The
analog signal
bandwidth is 0-95
Hz (-6dB) when
configured as an
eight channel unit.
The measurement
accuracy is +/-0.5
% (without
sensor). The
CT4/8-Wheel is
suited for
operation at
ambient
temperatures of
-20 to +70°C. The
transmission
distance between
transmitter and
receiving antenna
is of the order of
10m (30 feet) - depend
of application!
