The sensor device is composed of a front shell, packaging terminals, a main body, an insertion pin, a PCB, a Hall chip and a sealing ring. The sensor device is characterized in that the PCB is equipped with a high-precision resistor and a high-precision capacitor, a first pin of the Hall chip IC is connected with the terminal 5V, third and fourth pins of the chip IC are connected with the terminal GND, a second pin of the chip IC 7 is connected with the terminal Vout, the resistor and the capacitor are installed on the PCB, the resistor is connected between the first pin and an output port of the chip, and the capacitor is connected across a ground wire connecting the first and second pins and the third and fourth pins. The sensor device is simple in structure and reasonable in design; the measurement accuracy of the sensor is improved and the performance of a motor is more reliable due to the introduction of the reasonable and accurate resistor and the appropriate capacitor; and the measurement result is accurate due to the adoption of the high-precision chip and the auxiliary resistor.
Description
Technical field
The utility model relates to a kind of device of testing camshaft location, especially detects the sensor device of the camshaft location of automobile.
Background technology
At present, as critical piece in the electro jet car oil spout electronic control system: CMPS Camshaft Position Sensor, CMPS Camshaft Position Sensor, its function is the electric signal that the camshaft position is provided to miniature control system (ECU), the cylinder compression top center of miniature control system (ECU) by the program calculation engine is again according to corresponding duration of ignition of calculated signals of other sensor.So the result precision of CMPS Camshaft Position Sensor test directly influences the operating mode of engine.This class sensor on the market, shortcoming are that the sensor internal spatial design is too loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of automobile sensor device that detects camshaft location simple in structure, reasonable in design is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of automobile sensor device that detects camshaft location, by procapsid, package terminal, main body, contact pin, pcb board, Hall chip IC, O-ring seal is formed, it is characterized in that: high-precision resistance and high-precision electric capacity are installed on the pcb board, the 1st pin and the terminal 5V of Hall chip IC join, the 3rd pin of Hall chip IC, the 4th pin and terminal GND join, Hall chip IC the 2nd pin and terminal Vout join, resistance and electric capacity are installed on the pcb board, resistance is connected between the 1st pin and delivery outlet of Hall chip IC, and electric capacity then is connected across Hall chip IC the 1st pin respectively, the 2nd pin and the 3rd, between the ground wire that the 4th pin links to each other.
The utility model has the advantages that:
(1), simple in structure, reasonable in design owing to introduced rationally resistance accurately, appropriate electric capacity, and the measuring accuracy of this sensor is improved makes engine performance more reliable;
(2), the utility model is owing to having adopted high-precision chip and auxiliary resistance, so test result is accurate.
