What you are seeing here is our crystal clear acrylic vacuum chamber, hinged side door with clamps. In addition, our client has asked us to add 1. A quantity of two high power feedthroughs on the top right wall, 2. An 8-pin power connector, and 3. a multi-pin feed through. These vacuum feedthroughs enable the routing of electrical power and signals from the outside of the chamber into the inside of the chamber without disrupting the vacuum.

The Feedthroughs are fully fastened to the wall and hermetically sealed by an O-Ring or Vacuum epoxy. The advantage is that the electronics can be connected and a vacuum can be pulled without leakage.

If we open the door, we can see the power cables perturbing into the inside of the chamber. Here, our client is able to connect these wires to their electrical device, close the door, and pull a vacuum. Because the walls are made of cast transparent acrylic, the electrical components inside the chamber fully visible during the test.

Our clients prefer to work with us because we are Experts in Vacuum Science and Technology. There is a tremendous amount of valuable resources and information regarding vacuum systems and vacuum technology; check them out by clicking on the links below.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: Custom Vacuum Chamber with Blank Plate
You are looking at our standard Acrylic Vacuum Chamber, Hinged Door with Clamps. There is only one difference; this vacuum chamber has a blank acrylic plate that is connected to and aluminum plate which in turn is anchored to the side wall of the acrylic vacuum chamber. This blank plate is there to enable our client to add vacuum feedthroughs to the side wall in the future

How do you know that you have a good part during your leak test? In order to understand your leak test, you must first understand the Test Decay Curve and what it tells you about your test specimen. There is a certain way that a test specimen behaves during the leak test.
