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.

Acrylic Vacuum Chambers
Acrylic Vacuum Chambers are, as the name implies, vacuum chambers made from the Acrylic Polymer. There are several advantages to acrylic vacuum chambers the three main ones being 1. Fully Transparent, 2. Cost Effective, and 3. Versatile and Highly Customizable.
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: High Altitude Vacuum Testing of Electrical Connectors and Components
This was an interesting project where one of our customers needed to test wires up to 44 inches long within a high altitude simulation environment. In addition to testing wires, several other electric connectors required altitude testing as well. The altitude requirements were 100,000 feet (30.510 km) which corresponds to 8.36 Torr - a piece of cake when it comes to the vacuum requirements of our chambers.
