TEMPTEL8-Wheel is an small telemetry system designed for easy mounting onto
rotating Wheels to provide non-contact transmission of temperature
measurement.
Sensors
inputs are connected via screw clamp. Measured values are prepared in
analog format, digitized (12bit) 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 water protected to IP65 specifications.
The
following thermocouples can be connected: Type K -50 to 1000°C or Type J
-50 to 750°C.
All inputs
are full galvanic isolated!
The
measured values are processed and output as +/-10V analog signals (linearized
for K or J) at the BNC sockets (Opt. CAN-BUS) on the stationary receiver located in a vehicle.
Resolution
of 12 bits is standard; this enables an amplitude dynamic of 72 dB. The
analog signal bandwidth is 0-30 Hz (-3dB) when configured as an eight
channel. The measurement accuracy is +/-0.5 % (without sensor). The
TEMPTEL8-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 up to 10m (30 feet) - depend of application!
