1. Silicon diaphragm Master side measuring DreSSUre Work side measuring pressure Glass Differential pressure range The differential pressure sensor is very compact and it has high pressure resistance and simple construction which consists of less moving parts therefore it is excellent in anti vibration and durability Furthermore the variation over the years for the output signal is small and that works well to protect the problem Generally compared with conventional differential pressure sensor the internal volume displacement of this sensor is very small2. When no master is used compared with the case of using the master a large change of differential pressure Or drift occurs due to the compression heat during pressurization the change of intemal volume etc In such case the change of differential pressure that occurs during detection time can be stored and then subtracted from the data of inspected products to extract the change of differential pressure that corresponds to actual leakage This greatly cuts detection time NG Fail OK Pass correction data AP Onlyleakdiferential Detect differential pressure pressure AUTO ZERO Charge Balance Detect Time Balance time RS 485 1 5
