Telemetry in Practice:
Real-World Applications of imc Measurement Technology
At imc, we deliver state-of-the-art telemetry solutions for environments where precision, reliability, and flexibility are critical. Our telemetry systems are designed to adapt to complex installation challenges and enable robust, contactless data transmission, even under harsh operating conditions.
Our application engineers bring decades of experience in tailoring electronic and mechanical designs to customer-specific requirements across industries.
Wheel Measurement on SkyTrain Düsseldorf
The development of digital multi-channel telemetry technology dates back to 2005, with one of its early applications in the SkyTrain Düsseldorf project. The SkyTrain connects the terminals of Düsseldorf Airport, operating under intense mechanical stress. To better understand real operating loads, engineers needed to measure the forces acting on each wheel during operation, which is a significant challenge given the constant motion and vibration.
To accommodate such purpose, each running wheel was equipped with six strain gauges, whose signals are processed via the multi-channel MT32 telemetry – the predecessor of imc’s MTP-NT. Data is transmitted directly from the rotating wheel to a stationary receiver.
This setup enables continuous, interference-free measurement of dynamic forces, providing the insight needed to ensure safety and optimize design.
Telemetry for Airborne Application
Tough applications, such as load testing on aircraft propellers, require high-precision telemetry systems. The imc CTP-NT-Rotate telemetry system was developed to precisely meet such demands. The application of this telemetry system is testified by our customer - CURTI industrial group, a family run business with more than 40 years of experience in defense and aerospace subcontracting and co-engineering. CTP-NT-Rotate was utilized by CURTI Costruzioni Meccaniche Spa in their flight test sessions of the ultra-light helicopter.
In more details, fully waterproof and rated for altitudes up to 6000 meters, the CTP-NT-Rotate enables simultaneous acquisition, conditioning, and transmission of up to 32 strain gauge signals directly from the rotor. Key features include:
- Remote configuration via Bluetooth (measurement range, auto-zero, and internal shunt calibration)
- Completely contactless and wear-free operation
The CTP-NT-Rotate system guarantees stable, accurate, and maintenance-free data transfer even under the extreme environmental conditions of flight testing. When installation space is limited, for example because a parachute mount takes up available room, imc offers the MTP-NT as a compact and flexible alternative. Its modular design makes it especially well-suited for telemetry on rotating components where space constraints demand a smaller solution.
Compact Telemetry for Automotive Shafts
Traditional torque measurement on vehicle output shafts involves mounting strain gauges and telemetry components externally. But with the shaft’s constant motion and joint flexibility during operation, the air gap between transmitter and receiver fluctuates, often causing unstable signals or complete transmission loss.
In this case, a fixed pickup head for data and power transmission is not possible. The perfect solution is Dx telemetry with inductive power transmission by Dx ring stator and Dx-SCT radio transmitter for strain gauges connection.
Here, the sensor and telemetry unit are fully enclosed within the shaft assembly, while the ring-shaped power transmission and the Dx-SCT radio transmission module are mounted directly at the test environment at the axle shaft. This smart setup was employed by Beijing M-Stars to test the real torque response.
Configurated suitably for the purpose, our Dx telemetry and sensor solution ensures error-free data transmission, even under dynamic driving conditions.
Precision in Motion
Whether in railway, automotive, aerospace, heavy machinery, or energy applications, imc telemetry systems empower engineers to measure, analyze, and understand complex mechanical loads without physical contact or signal degradation. From optimizing transport safety and supporting flight testing to improving drivetrain efficiency, imc delivers measurement technology tailored to the demands of modern engineering.
