Inductive transducers are self-generating, whereas passive transducers are passive. The fundamental electrical generator is utilized by the first type, which is self-generating.
When a conductor and a magnetic field move together, the electric generator principle states that the conductor produces a voltage within the field.
With the help of measured data, inductive transducers can be made to work by changing the flux. This obviously changes the inductance, which can be calibrated using measured data. As a result, inductive transducers operate according to one of the following tenets:
Eddy current production, as well as a change in mutual inductance and self-inductance
The Global Inductive Transducers market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Businesses are moving away from traditional inductive devices like potentiometers, optical encoders, and magnetic encoders in favor of a new generation of inductive transducers. A shift away from optical encoders has aided this trend, as many engineers have discovered the hard way that optical devices are unsuitable for harsh environments.
In contrast to bulky spools of wire, this new generation of inductive sensors makes use of printed circuits on flexible or rigid substrates.
The fundamental physical principles that underlie these new sensors are the same as those that underlie traditional inductive sensors. The new sensors are lighter, less expensive, and less bulky thanks to their laminar constructions, the very characteristics that have restricted the application of conventional inductive transducers.
The IncOder (from “inductive encoder”) series of angle encoders from Cambridge-based Zettlex serves as an illustration of this new generation of inductive devices.The layout is simple by design:two flat rings, one of which is stationary and the other of which rotates.
DC power is supplied to the stationary component, which transmits absolute digital data of up to 16 million counts per revolution.There are no contacts, bearings, seals, or requirements for precision installation or maintenance.Since the designs can be easily tailored to meet specific application requirements, this new generation offers design engineers significantly more flexibility.
From miniature rotary devices to linear, curved, 2D, and 3D shapes, almost any shape can be used.Shafts, bearings, seals, couplings, and housings can all be eliminated from the design if specified early on, further reducing weight, space, and cost. EMC performance is typically comparable to resolver or LVDT performance.
In fact, safety-critical aerospace and military applications are choosing new generation inductive devices because of their ability to design sensors for tight space and weight constraints.Additionally, the choice for the associated electronics of the new generation of inductive devices is 21st century because they were developed in the 21st century.
This indicates that separate signal conditioning electronics are not required.Instead, straightforward on-board electronics are utilized to generate high-speed position data in CANbus, SSI, SPI, A/B pulses, and other formats.Additionally, analog outputs such as 0-5V, 0-10V, 4-20mA, and others can be generated.
