Testing products bound for space is a little different for a few reasons, including the lack of air for heat transfer and general level of criticality, no possible service once deployed plus the general high-stakes nature of the whole endeavor.
It is well known that test and evaluation of production items is a very important part of producing quality products.
Thermal Vacuum testing basics Thermal vacuum chambers provide environments that most realistically simulate the environment in which products and components will be used. For aerospace, the satellite and space vehicle systems, subsystems, and components must pass carefully planned environmental testing to ensure reliability and safety. Thermal vacuum chambers have been used for many years of […]
Primarily to verify that the product will work properly in the environment (thermal and otherwise) that it is intended to perform. Sometimes, also to discover end-of-life issues for products, maximize performance or to weed out early failures that might result in product failures
Cascade Temperature Algorithm Demonstrates Thermal Testing Goals Reached Faster with the Potential of Differential
Many times, there are parts of a device to be tested that have different heat capacities and also possible active load heat sources. A single point temperature control algorithm can have trouble effectively dealing with these variables. Additionally, while it may be tempting to say that a temperature setpoint has been achieved when the numbers on the display panel reach the desired value.
Thermal testing testing of products can’t be ignored. Knowing your product stands up to the harshest environments it will be exposed to over the life of the product provides proof of the design and verified quality. With TotalTemp Temperature Chambers and Thermal Platforms you can most effectively run thermal tests for burn-in or design/production verification.
Synergy Nano Temperature controller has many cost saving and time saving features.
Liquid Nitrogen has the ability to provide the fastest ramp rates and achieve the coldest temperatures. Temperatures down to -100ºC or colder are achievable with ramp rates over 50ºC per minute. Typically the full range is not needed but in the event that future testing requires yet colder temperatures it is good to have the capability built in and not have to replace equipment.
Heat transfer via conduction is generally faster and more efficient. Depending on your purposes, conduction has a some clear performance advantages and some limitations which we will talk about. In general however, when appropriate conduction is often the best choice for performance.
Capitol Equipment and Tech time are always expensive….there are many costs involved with time spent waiting for a test to complete. Waiting for temperatures to be achieved is a big part of the time required for thermal test.
