The Model 3510 Safety Test Chamber is completely self-contained and only requires an external supply of dry nitrogen (or other inert gas) and a 115 VAC power source for operation.
All operating controls and elements, including a regulator for the gas supply, 10:1 booster pump, source pressure gauge, regulated pressure gauge, test pressure gauge, control and vent valves, and a mechanical timer, are housed within the unit. The pneumatic and electrical wiring schematics below depict the various test chamber components.
To set-up for testing, the item undergoing evaluation is connected to the quick-disconnect discharge port inside the test chamber via a flexible braided stainless steel jumper hose. A nitrogen supply is also connected to the inlet fitting on the side of the chamber to facilitate testing. After the chamber door is closed and locked, the gas shutoff valve and regulator are opened, and pressure is metered to the test item using a precision soft seat control valve on the front panel. A 4.5-inch diameter test gauge mounted in the center of the front panel indicates the pressure being applied to the test item.
