non-contact, high-precision, modular
A sensor telemetry system is a complete measuring system and consists of several components.
The diagram shown here is intended to provide a basic understanding and to explain the individual components.
A sensor telemetry system can be divided into 5 blocks:(click on block to view related products)
Record the variable to be measured and transmit this as a raw measured value to the measuring amplifier.
Prepare the signal for transmission. The signal is digitized and error compensated.
Inductively, via a high-frequency electric field, using a rotor and stator antenna.
Data reception by a stator antenna. Data is demodulated and checked.
Data transfer for recording or remote configuration of the measuring chain to a PC.
The core task of the sensor telemetry system is the contactless data transmission based on a high-frequency electromagnetic field. The rotating part, in most cases inductively fed by the HF field, is used for this purpose. This means that the complete rotating part, consisting of the sensors, the measuring amplifier and the rotor antenna are supplied inductively.
This and the fact of contactless data transmission makes our sensor telemetry maintenance-free!
The stationary part of the sensor telemetry system generates the HF field and establishes the coupling with the rotating part. The data transmitted via the high-frequency field are modulated onto the carrier frequency of the HF field and are decoded by the evaluation unit where they are available as a digital data stream
