We at MANNER Sensortelemetrie GmbH have specialized in non-contact sensor signal data transmission for industrial applications. We solve contactless, bidirectional sensor data transmission problems of rotating or moving parts.

Therefore, we develop, produce and deliver:

  • Single and multi-channel telemetry systems with highest sampling rates (>400 kSample) in modular design in inductive and radio technology
  • Customer-specific telemetry systems for special problems
  • Rotating torque transducers for test bench and industrial applications – customer specific.
  • Cost-effective torque transducers on OEM basis.
  • Cost-effective, customer-specific transmission systems for series production.

What are 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 large blocks.

  • Sensors
  • Measuring Amplifier
  • Transmission
  • Evaluation Unit
  • Data Reception

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.


We, the MANNER Sensortelemetrie GmbH, 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

Measuring Amplifier

The measuring amplifier processes the raw value of the sensor. Error compensation at the highest level is already carried out here.

Correction polynomials are stored in the measuring amplifier to compensate for a zero drift or temperature drift of the measured variable. Thus, a highly accurate digital measuring signal is available which can then be transmitted without contact.



MANNER Sensortelemetrie GmbH offers the solution of a problem. In order to define the suitable transmission technology for you, we are at your disposal with our know-how and almost 30 years of experience.

The advantages of inductive transmission are complete freedom from maintenance over decades and insensitivity to interference. MANNER has various transmission frequencies which cover shaft diameter ranges from 10 millimeters to 5 meters. Inductive systems are characterized by:

  • Absolutely interference-free operation
  • Extremely miniaturized construction (12 x 12 x 3mm)
  • Environmental resistance (up to 2000°C)

We offer standardized couplings of rotor and stator antennas as well as customized solutions for challenging tasks.

MANNER also offers transmission via WIFI. Several free frequency bands are available for this. With WIFI transmission, higher bandwidths can be handled than with purely inductive systems. We will be pleased to advise you here too.

Particularly advantageous are the systems for inductive or WIFI operation that can be configured by the customer. In WIFI operation, the system can be powered inductively or by batteries. This allows both short-term measurements with batteries and operating times unlimited in time using inductive operation.

Evaluation Unit

MANNER Sensortelemetrie GmbH offers various forms of a data evaluation unit. From compact designs with integrated stator antenna and compact tube housings up to 19-inch plug-in units for test bench applications.

Depending on customer requirements, a wide variety of output signals can be realized. To name a few:

  • Analog voltage output
  • Analog current output
  • Analogue frequency output
  • Digital data USB
  • Digital data CAN
  • Digital data EtherCAT
  • Digital data Ethernet PTP
  • Digital data of ethernet earth

Data collection and data analysis

The data recorded by the evaluation unit can be transferred to a PC. There the MANNER data recording software can be used to view the data, record them and remotely configure the measuring chain.
