Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of high temperature resistant, low noise cable of anti-intense radiation that detects tiny signal.
Background technology
Along with developing by leaps and bounds of science and technology, in fields such as atomic energy industry, boats and ships, aerospace industry, medical industries, the small direct current of various measurements or pulse signal system all require to use low noise cable.This class measuring instrument is that physics, chemistry or small change of variable are medically become to the small signal of telecommunication, then through high impedance, high-gain amplifier, amplifies to measure.
Therefore cable itself the factor generation interior noise such as expand with heat and contract with cold because bending, vibration, impact, extruding etc. can make effect that cable is tending towards being out of shape and variation of ambient temperature cause, this noise generally is referred to as the triboelectrification noise, can bring error to measurement.When variation of ambient temperature, as when carrying out high low temperature cyclic test, found some low noise cable, also can produce this noise simultaneously.Due to the thermocurrent that the variation of cable environment temperature produces, may become the noise source of low current signal transmission system and measurement result is exerted an influence.
The utility model content
