Affect the output of the acceleration sensor external inductive interference can be divided into the following

Affect the output of the acceleration sensor external inductive interference can be divided into the following categories: electrostatic induction interference: electrostatic induction is due to two branch circuits or parasitic capacitance exists between the components , so that a branch road through the parasitic capacitance of the charge transferred to another one slip up , sometimes also referred to as capacitive coupling.Electromagnetic induction interference: when there is mutual inductance between the two circuits when a change in current in the circuit will be coupled to another circuit by a magnetic field , a phenomenon known as the electromagnetic induction . In this case , when the acceleration  Sensor Camshaft used frequently encountered , particularly attention.
Leakage current sensing interference: the electronic circuit inside the element holder , terminal, printed circuit boards, capacitors internal media or poor insulation shell , especially acceleration  Engine Water Temperature Sensor  humidity increases, resulting in decreased insulation resistance insulator , then the leakage current will increase , which caused interference. In particular, when the drain current flows to the measuring circuit input stage , its impact is particularly severe .
RFI Interference: mainly large power equipment start-up, operation stops , and the interference generated higher harmonic interference.
Other disturbances : mainly refers to the system and poor working environment , but also susceptible to mechanical interference , thermal interference and chemical interference and so on.
