Inductive Technology
Why choose inductive?
-
Low cost, robust to environment, tolerant of geometric misalignments
-
Easy to integrate into products or applications
-
High reliability automotive-standard components available from a range of manufacturers
-
Straightforward to provide additional functionality - for example temperature or condition monitoring
-
Suitable for many sensing geometries - rotary (single or multiple periods), linear, dual channel for safety critical applications, very high resolution through coarse/fine channels for accurate and precise measurements
-
Utilises standard printed-circuit-board process with a reliable supply chain
-
Capture more of the value in your product and vertically integrate your supply chain by manufacturing your own sensors, alternatively you can use our manufacturing partners.
​
What we do ...
Sensor methods can help you integrate inductive sensors into your products by providing application engineering and support, such as:
​
-
IC selection
-
Inductive coil design and simulation
-
Sample production and test
-
End of line programming and testing support
-
Statistical and Monte Carlo analysis of performance and reliability
​
We have extensive experience with inductive systems, operating in fields with demanding and safety critical applications, successfully bringing hundreds of millions of parts to market. This has been achieved through a deep knowledge of inductive technology, broad manufacturing experience, and methodologies to assess and verify performance over lifetime, temperature, and tolerances.
​
From sensor design to sophisticated statistical and Monte Carlo analysis of performance, we have a suite of design and simulation tools to ensure a dependable sensor solution.
Principles of operation
A transmit coil is supplied with AC current at MHz frequencies, this produces an alternating magnetic field
Configured for your application
The sensor can be configured with multiple independent sensing channels: for redundancy in safety critical applications; or to provide a high precision 14+bit measurement
Linear sensors are well suited to control and automation applications, for example valve positioners
Segment sensors are good for large applications or where space is limited - with some reduction in accuracy
Mass market inductive sensing: driven by automotive
Inductive sensing is based on two physical laws of electromagnetism: Ampere's law where a current produces a magnetic field; and Faradays law of induction where a changing magnetic field induces an EMF in a conductor.
These two principles are the foundations of the technology, and the development of reliable and low-cost electronics has allowed the fundamental strengths of the technology to be realised, leading to widespread adoption in the automotive industry.
​
It is now the dominant technology for many position sensing applications and, as such, benefits from robustness to environmental factors (e.g., water, dirt, magnetic fields), low cost and automotive qualified components.
​
Its slim form factor, ease of manufacture and relative insensitivity to geometric tolerances make this an attractive technology choice for integration into products.
