Inductive Sensor Working and Applications

Nowadays, we cannot imagine automation without using an inductive sensor. When automation is used, for detecting the non-contact position of metallic things, wear-resistant are mandatory, whether in electronics production, mechanical engineering, automotive, plastics or food, industries. There are many industries offering a broad range of sensors with a variety of designs for almost any application. Some kind of sensors has an extra ceramic coating so that it can be weld. By using these sensors, we can monitor, automate, & control conditions and processes at the maximum quality, even in severe environments.

What is an Inductive Sensor?

At present, Inductive sensor is an essential component used in machines. These sensors are robust devices and mainly designed depending on the requirements of the proximity sensor. These sensors detect conductive otherwise metallic parts where contact is difficult. These sensors are used in hygiene based and outdoor applications.

The designing of these sensors can be done based on the particular application. For instance, multi-voltage and high-temperature sensors. These sensors give suitable signals for limits & positions which works like a pulse pick-up used for checking counting tasks as well as rotational speed. When these sensors are used in a non-contact form, then it can be last for a long time because they are not focused on any mechanical wear & tear. And also, these sensors are opposed to severe environmental situations like dust, vibration, & moisture to make them the perfect choice to use within numerous industries.

Working Principle

The working principle of an inductive sensor mainly depends on the electromagnetic induction principle for detecting or measuring objects. Inductive sensor mainly includes an induction loop which is enough for detecting electromagnetic. The working of these sensors can be done by generating an oscillating electromagnetic field which is formed by a magnetic object when it is in motion. The moving object activates the current flow within the induction loop likewise with Faraday’s law of induction. So that changes will have occurred within the electromagnetic field. So it can be detected with the circuit of sensors. A suitable signal can be an output when a magnetic metal is noticed.

Applications of Inductive Sensor

The applications of these sensors include the following.

  • These sensors are extensively used in industries, military, robotics, rail, aerospace, etc.
  • Used in Proximity sensors or switches
  • These sensors are used to notice ferrous metals like iron, steel, nickel, and cobalt.
  • Used in the medical field for MRI (Magnetic Resonance Imaging)
  • It is used to assemble the automotive body
  • These sensors are used for detecting motion position & controlling the motion of an object
  • Used in the production of transformer & coil
  • Used to detect lid and broken bit
  • Used in traffic sensors for noticing the moving car
  • These are used in eye tracking and the search coil production
  • These sensors are used to detect the existence of an object within the application like pick & place throughout inspections
  • Used in machining procedures
  • Used in metal detectors
  • Used in automated industries
  • These are used in limit switching, speed detection and generation of pulse
  • Used to convey otherwise system control
  • Used to measure the distance & position of the tool

Thus, this is all about the inductive sensor. The main advantages of inductive sensors are appropriate for a range of applications, easily wearable, contact-free, as opposed to dirt and short circuit. Here is a question for you, what are the drawbacks of an inductive sensor?
