The TabulatedThermistorCurve table of valve NTC is compareed.
Scene measures gas cylinder valve temperature sensor using multimeter, then compares cylinder valve NTC's
TabulatedThermistorCurve table is compareed.During actual measurement, since the mode of operator is different, survey
The position of amount is different, causes with a valve under same ambient conditions, and the resistance value of measurement is different, and then causes to correspond to
The temperature tabled look-up is different.Cause to be unable to accurate judgement valve whether can correct display environment temperature.
It is every valve of guarantee because not can determine that whether its temperature function is effective caused by manual measurement method, and then differentiates
Whether valve is qualified.A kind of more reasonable gas cylinder fixed structure must be designed thus.
