The working principle of sensor of effect of analytic Huo Er and sensor of magnetic flux door
[introduction] in car domain, magnetism sensor is one kind is lost sight of but indispensable technology, it can make from turn signal becomes a possibility to everything of spark timing.

In car domain, magnetism sensor is one kind is lost sight of but indispensable technology, it can make from turn signal becomes a possibility to everything of spark timing.
In your car, these small sensor the likelihood amounts to 70, they carry out what be gifted silently all sorts of functions, make you OK move smoothly from destination A destination B.
“ and other are very much use hold together the semiconductor device that modern production life runs normally is same, the user is invisible magnetism sensor, but to those we already a lot of functions of be accustomed to sth, it is acting decisive part however. ” craft develops say of manager Ricky Jackson.
Magnanimity application
Magnetism sensor omnipresent, dimension is cabinet and the price is reasonable, OK and relaxed ground and other circuit together compositive go up to chip, accordingly, magnetism sensor is used extensively at all sorts of application by people.
Magnetism passes feeling technology the advantage in robot and factory automation especially apparent. Because magnetism sensor is in,spare parts position and speed detect the respect has higher reliability and precision, accordingly, its to athletic control character is crucial. This one advantage also lets machine arm and other component can move well and truly, ensure thereby the production process of high quality and high security.
Outside removing a car, magnetism sensor still is used at waiting for electric home appliances<gj like washing machine and microwave oven in great quantities in, in order to detect the door of the machine is to be in shut or open position. Magnetism sensor still is used extensively in medical apparatus and instruments, for example, when applying at Acousticon, it can detect whether did the person that adorn carry a mobile phone, change next to corresponding mode, the person that adorn in order to help can more hear an incoming message clearly. In addition, the floor that it often still is used in elevator detects and detect for example flat computer or mobile phone holding facility is to be in the position that open or closes.
Working principle
The working principle of magnetism sensor is become voltage or voltaic news through changing magnetic field. Because the interior of sensor moves not to need to be contacted actually with exterior component, accordingly, magnetism sensor becomes what the ideal that the environment pollutes reduces in car and industrial environment to choose, at the same time it still can reduce what arise because of the attrition between package to wear away, the maintenance that drops device thereby cost.
Magnetism sensor has varied function, but want special those who point out is, the sensor that has two kinds of functions among them is OK by extensive and compositive to other circuit, that is sensor of suddenly Er effect and sensor of magnetic flux door.
Sensor of suddenly Er effect can move reliably in all sorts of electromagnetism environments, the times praise highly that suffers manufacturer and love. Common application includes oil to measure a watch, basically use at detecting the bobber in gasoline tank, at the same time it also can be used at notting have to brush electric machinery, detect rotor position undertakes timing to electric current. When magnetism sensor and other circuit are compositive, production process need not special material or undertake special processing, conduce to reduce design cost.
With Huo Er effect sensor is compared, sensor of magnetic flux door is more sensitive, it can detect the very slight change in magnetic field. The electronic compass that the application with commonly used sensor of magnetic flux door includes ship and plane and rocksy are used at detecting the instrument of subterranean structure.
New development
Heart state apparatus (TI) can offer a series of solutions related to effect of compositive Huo Er or sensor of magnetic flux door.
We are in “ the magnetic induction technology with sundry research and development, and its compositive to semiconductor technology in, in order to develop an all sorts of interesting new parts of an apparatus or appliance. Say of Ross Eisenbeis of ” system engineer.
For the engineers that use TI sensor in chip design to the hope, TI offerred those who abound piece on function and support. A series of tool and software can assist an engineer to make new design, and engineers also can be handed in in our forum shed a view and discuss optimal practice. Those who abound is online groom each character that can help engineers use TI magnetism sensor adequately and advantage.
Ross expresses, we are developing “ a series of new technology, the help designs an engineer to reach function and cost goal easily. In the meantime, we return the technical documentation that can provide a large number of facilitating to use for them. Our technologist and IC stylist people the development that also promoting these technologies continuously all the time. ”
