NTC temperature sensor for electric car
2012-09-18
NTC (Negative Temperature Coefficient) temperature sensor is composed of an NTC thermistor and a housing / shell / cap / case, and in addition, maybe a connector, a heat shrink tube, etc.
 
This type of NTC temperature sensor for electric vehicle such as electric bicycle, electric car, electrombile, etc. is composed of an NTC thermistor with resistance 10Kohm accuracy ±1% and beta value 3435K at 25℃/85℃ accuracy ±1%, a surface mounting / testing cap and a shrinkable tube.

Method of the Stockpile:
1. The height of stacks products cannot overbalance four boxes,in the stackpile and the course of transport.
2. The packing products of inside must placed desiccant.Allowance used the angone way to transport,but must prevent therain and the snow direct or indirect shower bath and damnification of these products.
3.The products are stockpiles candition of the tencperature is about -10℃/+40℃, the opposite humidity not bigger too 80%,acidic and alkalescent of substance,erode gas or radiant.
