Amphenol NOVA制動助力器監(jiān)測背面壓力傳感器模具P1905(0-300psi)

P1905壓阻傳感器芯片設計用于在腐蝕性（苛刻）介質中進行壓力測量。 管芯具有通過將硅帽密封低應力結合到器件晶片的頂側而形成的參考真空室。 通過從模具背面施加壓力，P1905傳感器芯片消除了頂側的傳感器電路與應用介質的直接接觸，允許P1905模具測量腐蝕性液體和氣體中的壓力。 使用NovaSensor的SenStable®工藝，P1905芯片具有出色的長期穩(wěn)定性和重復性（<0.1％/年典型值）。

Parameter	Value	Units	Notes
All values measured at 25oC and 5 V excitation, unless otherwise noted. Samples from each wafer are used to verify bridge resistance, offset, span, linearity and die performance in the temperature range between 0oC and 70oC. Backside burst pressure and operating temperature for sensor utilizing P1905 die can be lower than corresponding parameters for the die. Typical span is equal to 160 mV at 300 psi. Best fit straight line. Between 0oC and 70oC. Typical value.
