What are sensors used for?

Sensors play a central role in modern industrial environments. They are used to detect physical quantities such as temperature, distance, pressure, level or motion and convert this information into measurable signals. In this article, we discuss the most common applications of sensors within industry, with specific focus on how they contribute to process optimization, predictive maintenance and fire and hot spot detection.

What is a sensor?

A sensor is an electronic component that registers changes in the environment and converts them into a measurable signal. Sensors are used to make processes more efficient, safe and predictable.

Typical quantities measured by sensors:

• Distance or proximity
• Temperature
• Press
• Vibrations
• Levels (liquids or bulk)
• Smoke and heat (for fire detection)

What exactly do sensors do?

A sensor measures a certain value in the environment and converts it into an electronic signal that can be used for monitoring, control or automation. Examples include:

• Detecting the presence of objects
• Measuring temperatures in critical processes
• Tracking movement or distance between components
• Recording levels in silos or tanks
•

• Applications in process optimization

  In production environments, sensors are used to make processes more efficient and safer. For example:

  • Level measurement in storage tanks with ultrasonic or radar sensors helps prevent flooding or dry running.
  • Position Detection with inductive sensors prevents collisions between machines or parts.
  • Temperature measurements Optimize heating or cooling systems.

  Role in predictive maintenance

  Sensors contribute to predictive maintenance by continuously collecting data on the state of installations. Consider:

  • Vibration sensors that detect engine wear early
  • Temperature sensors that detect overheating of machinery
  • Pressure sensors that detect leaks or blockages in pipes

  This data can be analyzed to schedule maintenance at exactly the right time, saving costs and reducing downtime.
