Weiber thermal cyclic chamber is ideal for test requiring quick changes in specimen temperature. It features new technologies, such as a specimen temperature control function maintaining linear specimen temperature change rates during rapid thermal cycling, and temperature ramp control. It employs a wide variety of applications in Semiconductor, Automotive, Communications, (including Fiber Optic & RF Microwave), Aerospace, Military, Medical and other electronic and non-electronic manufacturing, engineering and production test environments. They are used to test the durability of a package undergoing extreme temperature variations over a given period of time.Our units offer maximum flexibility in both chamber size and performance for your most demanding temperature/humidity testing requirements.
Weiber temperature testing chamber is made of sus304 stainless steel plate while the outer bladder is made up of a3 steel plate sprayed with plastic. Double aEUR"layer high temperature resistant and high intensity seal is adopted between the chamber door and the chamber body in order to ensure the obscuration of the testing area. High low temperature test chamber control instrument adopts RS 232 or RS 485 communication interface and can connect to pc for corresponding operation. Our range of Temperature testing chambers are supplied fitted with a microprocessor controlled fully programmable PID control system, which can be used either as single set point controller for long term stability tests or as fully programmable controller for cyclic type testing.
Thermal cycling is achieved by convection heating and liquid nitrogen cooling. The chamber is also equipped with four pneumatic actuators capable of providing simultaneous repetitive shock vibration (RSV) stresses on fixture test articles across a wide frequency range. The vibration controller is equipped with several time-domain, frequency-domain and fatigue analysis software tools. The spectral distribution of the RSV shaker is fixed by design but can be altered to a limited extent with suitable load train and fixture design. The extreme simulation of temperature is conducted in two zones of hot and cold that can be controlled independently and an optional third zone.
The single basket product carrier moves vertically, from one zone to the other, subjecting the product to dramatic changes in temperature thus creating a temperature shock and thereby detecting specimen flaws. Thermal cyclic chamber have the variables that affect the pull down time or ramp up time of a chamber are the size, temperature range, and power of the heating or refrigeration system of the chamber. Acmas Technocracy has possessed a strong technical capability and a team of experts in the field of thermal cycling chamber.
