Thermo telemetry


TEMPTEL8 thermo telemetry system 4 or 8 channel

4/8-channel telemetry system for thermocouples K or J – inductive digital transmission from rotating shafts

TEMPTEL8 is a small telemetry system designed for easy mounting onto rotating shafts providing non-contact transmission of temperature measurement signals. Sensor inputs are connected by screw clamp. The sensor signals are conditioned, digitized (12 bit) and then transmitted via inductive coupling.

The following thermocouples can be connected: Type K -50 to 1000° C or Type J -50 to 750° C. All inputs are fully galvanically insulated. The stationary receiver provides an analog output of ±10 V for the linearized signals.

The TEMPTEL8 offers an analog signal bandwidth of 30 Hz (-3 dB) for eight channels. The measurement accuracy is ±0.5 % (without sensor). The system is specified for operational temperatures from -20° C to +70° C. The transmission distance between transmitter coil and receiving pickup head can be 5 to 100 mm – depending on the application!
