Engineering at the heart of connected systems
Sensors and actuators are present in most modern technical systems: industrial equipment, means of transport, buildings, infrastructure, connected objects, and more. They provide the essential link between the physical world and the digital applications that control it.
IT Link designs, specifies, and integrates physical-to-digital interfaces based on sensors and actuators. We work across the entire chain, from selecting sensors to business applications, including actuators, cabling, electronics, embedded systems, and connectivity. Our goal is to ensure reliable measurement, controlled operation, and actionable data.
The role of sensors and actuators in a system
In a connected system, the functional chain generally relies on three levels:
- The sensor measures a physical quantity and provides actionable information.
- The control unit processes this information and makes a decision.
- The actuator applies this decision to the process.
This pattern is found in production machinery as well as vehicles, energy installations, and building equipment. IT Link’s engineering services are built upon this architecture.
From signal to data: IT Link's expertise
Once the sensor-actuator chain is in place, the real value lies in the data produced and how it is leveraged. IT Link provides expertise across three complementary areas:
- Embedded systems : Software development for signal preprocessing as close to the source as possible (filtering, detection, aggregation).
- Connectivity : Integration of fieldbuses, industrial protocols, IoT or cellular (4G/5G) links, and interfacing with information systems.
- Data valorization : Designing dashboards, monitoring views, and predictive maintenance features to anticipate drift.

FAQ
A passive sensor modifies a physical property (such as resistance) and requires external conditioning. An active sensor has its own power supply and provides an analog or digital signal directly (e.g., 4–20 mA). IT Link manages the integration of both types of technology.
Retrofitting involves adding sensors and adapting actuators without replacing the entire machine. IT Link can integrate an additional measurement unit, instrument critical components (motors, cylinders), and relay data to a supervision tool.
No. IT Link is a service and consulting company. We do not sell catalog items. We conduct technical studies so that you can choose the most suitable equipment from your suppliers, with complete independence.
