Digital sensor according to the structure can be divided into three types

Digital sensor according to the structure can be divided into three types:
1 Absolute angle digital encoder structure of the sensor depends on its angular resolution digital encoder ( encoder ) digits. There are 14 products, such as an additional code channel and sub-circuit can be made 19 and 23-bit .
2 . Cycle counting  Crankshaft Positioning Sensor displacement resolution of this structure for low cycle count accuracy digital sensors, the only by the periodic nature of the signal generator . For example, when the length of 1mm grating has 100 engraved lines , its resolution is 0.01mm; pair of high-precision digital sensors in terms of cycle count , also taking into account the number of electronic breakdown . As precedent, at 100 times the electronic subdivision , this raster resolution is 0.1μm. This structure is incremental structures, structural characteristics ( direction of displacement required ) decided that it is not only identified with the circuit , but also has the reversible nature of the cycle counter . 3 . Press the oscillator frequency Cooling Temperature Sensor in the form of digital sensors can be divided into such a crystal resonator with and without crystal resonator two . The former , for the rejection by the measured points , was divided on the role of the quartz resonator quartz crystal resonant digital sensors and the role of energy storage in the resonator element with a crystal resonator FM digital sensors. Sensitive components by using the form , can be divided into four simple graph a) and differential Figure IV b) two kinds . From the above three types of  Car Temperature Sensor structure can be seen , they all have strong anti-jamming capability and digital output characteristics. If taking into account the fluctuation of the supply voltage , ambient temperature fluctuations and nonlinear compensation factors (not shown ) , the accuracy can be improved. If a single chip microcomputer to carry out information processing, such as compensation , frequency fold ( subdivision ) and digital conversion and other hardware lines may be software based , not only the line simplification , but also make the resolution, measurement accuracy and reliability is further increased
