In the design of temperature altitude chamber, there is a natural contradiction between maintaining the vacuum degree of the workroom (5kPa- normal pressure is adjustable) and meeting the power demand of the tested part. LIB has successfully solved this problem through technological innovation and launched two proven power-on solutions to provide a reliable test environment for customers in the military, aerospace, automotive electronics and other fields.
φ5-20mm precision holes are set on the side wall of the chamber (optional silicon nitride ceramic sealing ring), built-in customized socket module with temperature resistance grade: -20℃,-40℃,-60℃,-120℃~+150℃.
The use of aviation plug, through the double fluoro rubber seal,the working pressure range covers 1kPa~100kPa
The measured data show that both schemes can ensure the continuous maintenance of 0.5kPa low pressure environment for more than 72 hours at the limit temperature of -70℃~+150℃.
In addition to affecting the tightness of the product, the low pressure will also affect the heat dissipation of some heating products, electrical and electronic products, such as contactors, motors, transformers, resistors, etc., with the reduction of atmospheric pressure, the temperature of the cooling products increases.
Besides low pressure will also have an impact on electrical performance, high-altitude operation of the motor equipment, due to the reduction of atmospheric pressure, partial discharge often occurs near the strong electrode, and in serious cases, the air gap is broken down resulting in the normal working state of the equipment is damaged. Therefore, the LIB design is very necessary to test the performance of the product at low pressure.
As a custom specialist in the field of environmental test equipment, LIB has provided personalized solutions to more than 60+ international sub-customers worldwide. Whether it is a standard model in mass production or a customized version for special needs, LIB always leads the industry with accurate parameter control and reliable sealing performance.
