Low Pressure Leak Testing

Category: 
Cordis High Resolution Proportional Pressure Controls

Many popular consumer electronic products require strict leak testing to ensure protection from water ingress. Often, these devices are tested at very low pressures. All three of the products in this drawing are pressurized to less than 10 inches of water column (0.36 psig). The pressure is maintained in the DUT while the flow rate is measured. If the flow is anything but zero, the DUT leaks. Most products have a maximum allowable leak rate, so some flow is acceptable.
