Capacitance weighing sensor capacity by the electrode geometry restriction very difficult to do, generally tens to hundreds of micro method, even only a few micro method. Therefore, the output impedance capacitive weighing sensor is high, so the load capacity is poor, vulnerable to outside interference produced unstable phenomenon, serious and even unable to work. We must take shielding measures properly, to design and the use of inconvenience. Capacitance sensor also requires insulation resistance value is extremely high, otherwise the insulation performance of part as bypass resistance and affect the instrument, so we should also pay special attention to YLE Engine Temperature Sensors surrounding environment such as temperature, cleanliness, etc.. If the use of high frequency power supply, can reduce the output capacitance weighing sensor resistance, but the high frequency amplifier, sensor than low frequency complex, and the effect of parasitic capacitance, is not easy to ensure the stability of the work.Two shortcomings: output characteristics of nonlinearThe output characteristic of capacitance weighing sensor is nonlinear, although the use of differential type to improve, but YLE Camshaft Positioning Sensorcan not be completely eliminated. Capacitance sensor for other types of only ignores the edge effect of electric field, the output characteristics is linear. Additional capacitance or the edge effect will be directly superimposed sensor capacitor, the output characteristics of nonlinear.

YLE Coolant Temperature Sensor Motion sensor new direction
Now sensor technology has been greatly improved, the application of the sensor which has been around in various industries . The motion sensor is a sensor in one of the many types now Send a motion sensor 've got a new direction , the future will be more compact motion sensor , implementation costs will be cheaper .A digital compass mounted in a mobile device , a gyroscope and accelerometer located in a wide variety of location-based service application, and also used in some new ways of controlling a mobile device, such as by shaking and flicking operation control micro device . This YLE Automotive Temperature Sensors progress will be extended motion sensor range of applications, such as running shoes and tennis rackets can also be placed in the sensor , use a more simple manufacturing method for manufacturing a new type of digital compass. Next year , this technology will be applied to the GPS device. The company alsomanufactures accelerometers and gyroscopes prototype equipment , and plans combination of these three types of sensor digital compass on a chip traditional manufacturing methods are complementary metal oxide semiconductor (CMOS) fabrication method. This method is the most common method of microchips and electronic control circuit production. However, someconfigurations of the compass comprises a method of manufacturing such a magnetic field concentrator , it is necessary then to add up the chip produced , thereby increasing the complexity and cost of the chip . " The basic difference is our compass is completely manufactured in a standard complementary metal-oxide semiconductor YLE Crankshaft Sensor Replacementmanufacturing method completed . This new law enables the use of the Lorentz force due to the phenomenon of the compass , while most commercial digital compass use is a different phenomenon - Hall effect (theHallEffect), by passing a current through the conductor and measuring the change in voltage due to the Earth's magnetic compass so that the resulting work contrary, the Lorentz force when the current through the conductor material . magnetic force generated by a mobile device may be a Lorentz force on the object orientation determined by measuring the displacement of the Earth's magnetic field of the object .The chip is manufactured in a conventional silicon etching nanoscale MEMS (MEMS). There is a suspension of the elastic element of aluminum in the nanoscale MEMS devices. When a mobile device driven by the current through the aluminum when the bunch , there is no magnetic field generates a Lorentz force acts on the impact of resonance and aluminum . Two opposite sides of the aluminum metal sheet is detected by the change of the aluminum occurred. Small mobile device by measuring the change in capacitance produced on the two pieces of metal, it is possible to measure the magnetic field in one direction . Using a set of three such sensors , the mobile device can determine the direction and orientation of the Earth's magnetic field . "Compared with the conventional sensor , the MEMS and the combination of complementary metal oxide semiconductor technology will improve the sensitivity of the sensor , the sensor chip and reduce the volume and reduce the cost of the chip ." Nano group University of Southampton nanoelectronics professor HiroshiMizuta said.

The weighing sensor can be said to be one of the most important parts of a electronic scale
The weighing sensor can be said to be one of the most important parts of electronic scale, weighing sensor and then is in addition to IC, mainly for the two core elements, weighing sensor is itself an analog signal, when a weight to the weighing sensor at the top, in the sensor element elastic will produce a deformation, the change changes in the load YLE Engine Water Temperature Sensor at about 1mm. When the deformation, strain is stuck on the elastic element above meter fine wire delete will bend and try for, a total of 4 sheet resistance, according to the principle of Wheatstone bridge, when the resistance strain gauge and try for the resistance to bending when the 2 directions, one is the positive direction to a negative direction, we read his numerical is this difference, the difference of different deformation, YLE Car Temperature Sensorbut this is linearly proportional to the number of, of course there are some small error. This error because of the location and the material is affected, it is called nonlinear. So when a platform balance before we all need calibration and calibration, considered from the 2 aspects, one is the output, one is nonlinear. This is the primary output of strain gauge, the output signal is very weak, the normal condition, so the IC to the signal processing, allows the user to read to understand Kg and pound figure.
