How to get your coreIN Sensor

Please share the key data of your planned sensor integration with us in an email, feel free to include drawings, images, and CAD files.
In an initial orientation meeting, a sensor specialist will discuss the feasibility and desired configuration of the sensor, as well as any special requirements. The design will also consider the expected resolution and quality of the sensor.
We will prepare a quote for the sensor; we can calculate with parts provided by you or have them manufactured by our partners. A typical delivery time for new coreIN sensors is 8 weeks after order placement.
After delivery, a brief remote commissioning or instruction is included in our offer. If desired, our Data Science specialists can assist with the evaluation and processing of measurement data.

Advantages of Torque Driveshafts compared to conventional measuring adapters

Torque Driveshaft Integrated	Torque Sensor Adapted
No mechanical modification to the drivetrain	Mechanically modified drivetrain
Sensor and measurement electronics rotate with the shaft, Plug and Play	Stator and bearing block required, additional installation space
No wiring, integrated battery enables autonomous operation	Wiring and permanent power supply necessary
Configuration, data display, and logging via user-friendly app	Additional equipment and specialized know-how required
Additional measured variables: speed, 3D acceleration	Usually only torque measurement possible
All existing protective housings and safety systems are retained	Structural changes, often safety-critical
Suitable for field tests, real-world operation, and series applications	Primarily suitable for laboratory use

The simple way to measure torque

No modifications to the drivetrain – ready for immediate measurement
Wireless data transmission – flexible, mobile, secure
Intuitive app operation – no special hardware required
Suitable for development and series production – also for small series and individual pieces
Measuring range 0.1 ... 10 kNm - depending on shaft (expandable)

Industrial Driveshafts

For Industry and Vehicle Construction

Our preferred manufacturer for the integration of coreIN sensors into cardan, universal, and ball joint shafts is the Elbe Group.

Sensor Integration

The sensor integration is realized by a coreIN sensor, which is pressed into a precisely designed bore in the profiled inner part of the length compensation (sliding part). This creates a robust connection that enables accurate measurements without altering the design of the driveshaft.

The antenna and charging port are attached to the fork area using a plastic ring.

Power Supply

Power is supplied via an integrated, rechargeable Li-ion battery. Depending on the configuration, the battery capacity is 2,800 to 5,200 mAh.

This allows for a continuous runtime of 250 to 500 hours at a transmission rate of 1 signal per second. Depending on the application, this runtime can be significantly extended. Please feel free to contact us about this!

Frequency and Range

Depending on the application, a transmission rate of up to 1,000 signals per second is possible. Settings can be adjusted as required and easily via the voreVIEWER app.

Depending on the installation situation, the wireless range is up to 30 m. Gateways, external antennas, and repeaters also provide solutions for challenging environments.

Typical Data Processing

Visualization in the coreVIEWER App
Logging on internal memory or mobile device
PLC integration via coreGATE – e.g., 0-10V
System integration via coreGATE – e.g., TCP/IP or MQTT
Cloud Dashboard via coreGATE – e.g., LTE or TCP/IP

Typical Applications

Research and Development
Condition Monitoring
Predictive Maintenance
Safety Features
End of Line Testing

PTO Shafts

For Agriculture

Our preferred PTO shafts for coreIN sensor integration are the W2400 and W2500 series from Walterscheid.

Sensor Integration

Sensor integration is implemented using a coreIN sensor that is press-fitted into an S4 profile shaft. This creates a robust connection that enables precise measurements without changing the design of the drive shaft. This shaft can be cut to any length before integration.

The antenna and charging port are positioned at the end face of the shaft, ensuring no interference during operation.
