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! |
