Magnetic Sensor Systems
Readily available magnetic sensing chips (Hall, MR etc) offer reliable contact free measurements of current, speed, and position with easy integration. Successfully realising this potential requires a combination of specifying the appropriate magnetic materials, selection of electronics solution, and thorough system simulation to ensure robustness in the field.
We can offer all of these through our extensive experience in designing and modelling challenging magnetic systems.
Modelling and Simulation
To optimise a magnetic system, and ensure performance over lifetime, temperature and tolerances accurate system modelling is required.
This starts by understanding the system tolerances and environmental factors, and then building a model of the system. A variety of methods are available for modelling and optimising systems - from Finite Element to analytical approaches, coupled with statistical and Monte-Carlo analysis.
Component Specification
The foundation of any sensing system is the choice of measurement technology. There is an extensive selection of magnetic technologies to choose from for example, Hall, AMR, GMR, TMR - each with its own strengths and weaknesses.
We have strong links to a range of suppliers and can identify the most appropriate solution for your application - whether you are sensing position, speed or current.
Material Specification
Magnetic material will be a key part of any magnetic system. There is a wide range of magnetic materials to choose from, each with many grades.
Several additional factors also need to be considered to achieve best cost while guaranteeing performance and to avoid any demagnetisation effects over temperature and lifetime.
We can help you navigate these options to arrive at a specification which is right for your product.
