Saw excitated by input idt is divided axisymmetrily ( y type ) or centrosymmetrily ( s type ) into two pathes and detected by their output idts. there is a mass loading area located accurately in each acoustic path and fabricated by photolithography technology in y type and s type mass loading sensor devices. as the characteristics of saw sensor are greatly influenced by temperature, these sensors have one acoustic path for reference another acoustic path for measurement in order to reduce the influence of temperature
它們各自具有一個輸入idt和兩個輸出idt 。輸入idt激發的saw經過耦合器按軸對稱（ y型）和中心對稱（ s型）分成兩路，分別由輸出idt檢測輸出。在y型和s型saw質量沉積效應傳感器件的傳播路徑上都有一個由光刻工藝精確定位的質量沉積區。
