Portable Pressure Chamber and Custom Vacuum Chamber System

Portable Pressure Chamber and Custom Vacuum Chamber System
Portable Pressure Chamber and Custom Vacuum Chamber System
This portable pressure and vacuum chamber system is specifically designed and built to operate between an absolute pressure range of 60 kPa to 120 kPa. The pump is both a compressor and a vacuum pump. The maximum achievable vacuum of this pump is -25.5 inHg while the maximum achievable pressure is +15 psi or 30inHg. Keep in mind that if a more powerfully vacuum pump is used, a much higher vacuum is achievable because the acrylic pressure and vacuum chamber is capable of going into as low of a vacuum as the vacuum pump allows. On the over-pressurization side of things, the highest pressure this chamber is rated at is 15 psig (g for gauge pressure). This 15psig overpressure allows for water intrusion testing by simulating 10 meters of water depth when the chamber is filled with water and pressurized to 15 psig.

This is a complete system that includes the pressure and vacuum chamber, a vacuum and pressure pump, connection hardware, table frame structure with lockable swivel casters – making this a fully portable unit. There is one additional customization to this chamber and that is that it has an electrical outlet feedthrough on the left wall.

As a standard, each one of our vacuum and pressure chambers comes with two 1/4 inch NPT valves, a dial vacuum and pressure gauge, two lid handles, and a 15 psig safety pressure relief valve which will pop open if the pressure inside the chamber ever exceeds 15 psig. The inside dimensions of this chamber are 20 inch Wide, 20 inch Deep, and 20 inch High. Furthermore, there is a pneumatic toggle valve which allows the user a simple toggle between pressure and vacuum. When the level is toggled towards the front, the chamber is pressurized. On the other hand, when the lever is toggled towards the back, the chamber is subjected to vacuum. The toggle is of course labelled with “Vacuum” and “Pressure” and arrows pointing toward each direction. The lid comes with a total of 16 Thumb clamps, which swing out during openings, and are used to hold the lid down, and keep the O-Ring compressed during pressure operations. Yes, these are not required to be engaged during vacuum operations because the vacuum itself will pull the lid and compress the o-ring by default.

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.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
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.
