Telemetry Systems

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:

Sensors

Record the variable to be measured and transmit this as a raw measured value to the measuring amplifier.

Measuring Amplifier

Prepare the signal for transmission. The signal is digitized and error compensated.

Transmission

Inductively, via a high-frequency electric field, using a rotor and stator antenna.

Evaluation Unit

Data reception by a stator antenna. Data is demodulated and checked.

Data Reception

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

Sensors

We combine various sensors with our sensor telemetry system. This means that we select the suitable sensor for the variable to be measured together with the customer. Either this is done as a side order or as supply by us.

Our multifunctional systems can be adapted to almost any sensor. A selection of typical applied sensors is mentioned here as an example. This is not a complete list of available sensors.

• Strain gauges in ¼-, ½-, and full bridge circuit (recording of strains, manufacture of measuring elements for recording axial force, bending moment, torque …)
• Accelerometers
• Pressure sensors
• Temperature sensors (PT100, TC, others)
• Inductive displacement sensors
• Speed sensors
• Bearing encoder
• Angle encoder
