1 压力传感器 (1)压力的理解为了回答什么叫压力传感器,首先有必要对压力了解一下。压力是对物体表面单位面积内垂直方向的力(f)的大小, 用公式表示如下: P=F/A(P:压力 F:力A:单位面积) 压力的强度通常以压力的大小来表示。在地表面上的一切物体是在大气压下存在,所以表示压力的大小时,包含大气压的压力大小和以大气压为基准点, 即为“0”来表示压力的大小。有必要区别进行论述。
1 pressure sensor (1) understanding of the pressure In order to answer what is the pressure sensor, first of all it is necessary to understand the pressure. Pressure is the size of the force (f) in the vertical direction in the unit surface of the object. The formula is as follows: P = F / A (P: pressure F: force A: unit area) The intensity of pressure is usually expressed in terms of pressure . All objects on the ground surface exist under atmospheric pressure, so the size of the pressure indicates the size of the pressure, which includes the pressure of the atmospheric pressure and the atmospheric pressure as the reference point. It is necessary to distinguish the discussion.
