Electronic Integrity Testing inside Custom Pressure and Vacuum Chamber
One of our customers who designs and builds Electronic and Electrical Equipment reached out to us because they had a need for a custom acrylic pressure and vacuum chamber. They needed to subject their electrical components to a vacuum or pressure environments in order to test the performance of their electrical equipment.

What you are seeing is an acrylic pressure and vacuum chamber. We are looking at the chamber from the right wall. The right wall has a USB vacuum feedthrough and an 8 pin, 5 amp, power feedthrough. The rear wall has an electronic board installed towards the top. The left wall has QTY: 2 x Swagelok Type tube feedthrough, so-called liquid and gas feedthroughs, for a 0.25 inch OD tube. This is intended to be used to run coolant into the chamber during vacuum and pressure operations without compromising the vacuum or pressure operations. The reason there are two liquid and gas feedthroughs is because one tube is used to run the coolant into the chamber while the other is used to run the coolant out of the chamber.

The chamber dimensions are 12 inch Wide, 12 inch Deep, and 18 inch High. There are a total of QTY: 8 Thumb screws which are used to bolt the lid down during pressurization. The lid contains two valves, one dual pressure and vacuum gauge and one safety pressure relief valve that will pop open at 15 psig (the maximum allowable pressure for such chamber. The lid also has two lid handles. You will notice that the bottom wall has interesting design where there are a total of QTY: 8 x slots, 2 on each side. These are used to fasten this whole assembly onto a work table. Are you looking for a pressure or vacuum chamber? Do you need to customize it? Does it need to be robustly designed and quality manufactured to consistently perform and meet your needs? Contact us!

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Modified 14 inch Cube Vacuum Chamber for Degassing
This custom job was a modification to our standard acrylic vacuum chambers. When it comes to working with the Us Military, they want all specs to be met 110% and they want it yesterday. The military does not mess around which is why they came to us since we know how important it is to meet specs and ship fast.

An Acrylic Vacuum Chamber can be used to simulate elevation very reliably to altitudes up to 60.9 km or 200,000 feet. This provides several advantages over other testing methods as acrylic is transparent and enables full view of interior during testing. In this article, we will give you a through guide on what can be done to eliminate the risk of packaging damage during shipments at high altitudes.
