Description

Technical Field

[0001] The utility model relates to the technical field related to gas generator generation, in particular to a device for measuring the internal temperature of a gas generator. Background Art

[0002] Gas generators are widely used in the field of safety technology, for example, in airbags of motor vehicles or in pre-tensioned seat belts.

[0003] The transportation of gas generators must meet transportation certification requirements. This certification requires that the gas generators be placed in an oven at 105°±2°, but in practice, it is impossible to determine the internal temperature of the generator. Testing methods are needed to measure the actual internal temperature of the generator to meet these requirements. Existing measurement devices use temperature sensors that extend into the uninflated semi-finished gas generator. This lack of control over the temperature sensor's measurement position makes operation difficult and ineffective, resulting in poor temperature measurement accuracy. Utility Model Content
