TEMPTEL8is an small telemetry system designed for easy mounting onto
rotating shafts 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 inductive
transmission.
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 a 37-pole sub-d sockets (Opt. 0-20mA current
output) on the stationary receiver.
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 is suited for operation at ambient temperatures of -20 to
+70°C. The transmission distance between transmitter coil and receiving
pickup head is 5-100mm - depend of application!
