Application Overview: The differential pressure detector, with a high-precision differential pressure sensor as its core component, combined with advanced software algorithms, demonstrates powerful performance in the field of product inspection with strict requirements for air tightness. It can precisely detect even minor leaks.
Detection principle: The instrument simultaneously fills the standard sample or standard end with compressed air under a specified pressure, then stops the inflow and maintains the pressure. During the pressure retention process, a highly sensitive differential pressure sensor is used to measure the pressure difference caused by leakage between the tested product and the standard sample, and the pressure difference value or leakage rate is calculated.
