LPS331AP傳感器變送器的壓力傳感器、變送器規(guī)格書PDF中文資料

LPS331AP屬于傳感器變送器的壓力傳感器、變送器。由意法半導體集團制造生產的LPS331AP壓力傳感器、變送器壓力傳感器或變送器用于檢測并響應器件上作用力的存在或量變。壓力類型有絕對壓力、復合壓力、差壓、表壓、密封表壓、開關、真空和排氣表壓，工作壓力為 -100 PSI (-689.48 kPa) 至 20000 PSI (137895.15 kPa)。

Description

The LPS331AP is an ultra compact absolute piezoresistive pressure sensor. It includes a monolithic sensing element and an IC interface able to take the information from the sensing element and to provide a digital signal to the external world.

The sensing element consists of a suspended membrane realized inside a single mono-silicon substrate. It is capable to detecting pressure and is manufactured using a dedicated process developed by ST, called VENSENS.
