Configuring Sigma Chambers

 

Most Sigma chambers can be configured to meet virtualy any test requirements. Here are just some of the standards that we met using our standard high performance chambers.

Generally chamber companies make specific styles of chambers in limited sizes, for example they might offer 3 Shock chambers. The drawback to this approach is that you only have 3 choices, which means you will likely be shoe horned in to a chamber that is too large or too small for your needs.

Either option is bad, larger chambers waste floor space, which can be very expensive if you are building a production facility and very dear if you are cramped in a tiny test lab. And everytime you run tests it waste energy ($$$) as you heat and cool the extra air and chamber surface area that you don't need. Having too small a chamber can be equally bad, resulting in inefficient or ineffective testing. When a chamber is too small for the DUT (Device Under Test), there is not enough room for conditioned (Hot/Cold) air to circulate, which results in huge temperature differentials within the chamber. These temperature differentials mean that your DUT will be not be tested at the correct temperature, which means that you will not have met the Specs of your test. Worse yet, sever temperature differentials can actually damage or destroy DUTs. What you want is a chamber that is neither too large nor too small, so that when you run a test, you actually get the results you need and you do it in an efficient manner.

That is the essence of the Sigma approach. We start by finding the correct size chamber that best fits your DUT, and then we configure that chamber with options to meet your test specification, be it a MIL-SPEC, SHOCK, or some other standard. This is not a custom chamber (although we do make those too), but rather a high performance stock chamber configured with standard options to meet your exact test needs and the size of your DUT. The benefits of this method is efficency and lower long term cost. By having the right size chamber you save floor space which can be very costly in a production environment, or very valuable in a small test environments, it also saves you money every time you run a test, because you are not paying to heat and cool air and chamber parts that are not part of your test.
