Inductive distance sensors
Inductive distance sensors, also called – among other things – eddy current sensors, enable highly accurate, contactless, wear-free position measurement. All electrically conductive materials are suitable for use as a measured medium. External influences, such as electromagnetic fields, oils and water, do not affect the measurement result, as the magnetic field lines of the sensor pass through non-metallic objects unhindered.
Measurement principle:
Located in the sensor head is a coil that is supplied with a high-frequency alternating current.This coil generates an electromagnetic field. This electromagnetic field occurs field on the front side of the sensor and induces a voltage in the measurement object located in the electromagnetic field.This induced voltage generates a current flow, also known as an eddy current. This current flow generates a magnetic field that counteracts the magnetic field of the sensor. The superposition of the primary and secondary fields in the coil causes the coil impedance to change. The evaluation of this change yields an output signal that corresponds to and is proportional to the distance between the sensor surface and the measurement object.

Measuring principle
The sensor head contains a coil that is supplied with a high-frequency alternating current. This coil builds up an electromagnetic field. This electromagnetic field emerges at the front of the sensor and induces a voltage in the target located in the electromagnetic field. This induced voltage creates a current flow, also called eddy current. This current flow generates a magnetic field that counteracts the magnetic field of the sensor. The superposition of the primary and secondary field in the coil changes the coil impedance. The evaluation of this change results in a proportional output signal corresponding to the distance between the sensor surface and the measured object.

What are inductive distance sensors and how do they work?
Inductive distance sensors are electronic devices that are used to measure the distance to an object without physical contact. They are based on the principle of electromagnetic induction.
An inductive distance sensor consists of a coil that generates an electromagnetic field. If a metallic object comes close to the sensor, the object changes the magnetic field. This change is detected by the coil and converted into an electrical signal.
The mode of operation is based on the eddy current brake principle. If the metallic object comes close to the coil, eddy currents are generated in the object, which disturb the magnetic field of the sensor. This disturbance is detected by the sensor and converted into a signal that represents the distance to the object.
The output of the sensor can take various forms, for example as an analog signal or as a digital signal. The sensor can also have a switching threshold that generates an output signal when the distance reaches a certain value.
Inductive distance sensors are often used in industrial applications to measure the distance to moving parts, detect objects or control machines. They are robust, reliable and can also be used in environments with moisture, dirt or vibrations.

Which materials can be detected by inductive distance sensors?
Inductive distance sensors can detect metallic materials. This is because these sensors generate an electromagnetic field and react to changes in this field. If a metallic object comes close to the sensor, it changes the electromagnetic field and the sensor detects this change. Non-metallic materials such as wood, plastic or glass are generally not detected by inductive distance sensors.
What advantages do inductive distance sensors offer compared to other sensor technologies?
Inductive distance sensors offer several advantages compared to other sensor technologies:
1. Non-contact detection: Inductive distance sensors detect objects without contact, which means that they do not require direct contact with the object to be detected. This prevents damage to the sensor and extends the service life of the sensor.
2. High reliability: Inductive distance sensors are very robust and can be used under extreme conditions such as vibrations, dust, humidity and high temperatures. They can therefore be used in many industrial environments.
3. High accuracy: Inductive distance sensors offer high measuring accuracy and are able to measure even very small distances precisely. This makes them suitable for applications where precise positioning or measurement is required.
4. Fast response time: Inductive distance sensors have a fast response time, which means that they can detect changes in distance quickly and react accordingly. This makes them suitable for applications that require fast detection, such as in automation technology.
5. Low maintenance effort: Inductive distance sensors are generally maintenance-free and do not require regular calibration or cleaning. This results in lower maintenance costs and downtimes.
6. Versatile application possibilities: Inductive distance sensors are available in various versions and designs that are suitable for a wide range of applications. For example, they can be used in the manufacturing industry, in robotics, in the packaging industry and in many other areas.

How accurate are inductive distance sensors and what measuring ranges can they cover?
Inductive distance sensors are non-contact sensors that can measure the distance to a metallic object. They work on the basis of the principle of electromagnetic induction.
An inductive distance sensor consists of a coil that generates a high-frequency alternating field. If a metallic object comes close to the sensor, this alternating field is influenced by the object. This change in the field is detected by the sensor and converted into a distance value.
The measuring ranges that inductive distance sensors can cover vary depending on the model and manufacturer. Typically, the measuring ranges are from a few millimeters to several centimeters. However, there are also special sensors that can measure greater distances.
The accuracy of the measurement depends on various factors, such as the size of the sensor, the quality of the coil and the ambient temperature. As a rule, however, inductive distance sensors are quite precise and can detect deviations in the range of a few micrometers.

What factors can influence the measuring accuracy of inductive distance sensors?
The measuring accuracy of inductive distance sensors can be influenced by the following factors:
1. Material of the object to be measured: Different materials have different electrical attributes that can influence the inductance of the sensor. This can lead to inaccuracies in the measurement.
2. Surface quality of the object: Unevenness, roughness or coatings on the surface of the object can affect the measurement as they can influence the magnetic field of the sensor.
3. Distance between sensor and object: The greater the distance between the sensor and the object, the weaker the magnetic field and the less accurate the measurement can be.
4. Environmental influences: Electromagnetic interference, for example from other electrical devices, can influence the measurement and lead to inaccuracies.
5. Temperature: Changes in the ambient temperature can affect the electrical attributes of the sensor and the object to be measured and thus impair the measuring accuracy.
6. Sensor quality: The quality of the sensor itself can influence the measuring accuracy. High-quality sensors often have better accuracy and are less susceptible to external influences.
7. Calibration: Inaccurate calibration of the sensor can lead to measurement errors. Regular inspection and calibration of the sensor can improve the measuring accuracy.
It is important to take these factors into account when using inductive distance sensors in order to achieve accurate measurement results.
