MAP是进气歧管绝对压力(Manifold Absolute Pressure)的缩写。
进气歧管绝对压力(MAP)传感器用于测量进气歧管内绝对压力(真空度)的变化,并将其转换成电压信号,传送给发动机电控单元(ECU),ECU据此判断发动机负荷,结合转速信号,来确定喷油量。
进气歧管绝对压力传感元件由一片硅芯片组成。在硅芯片上蚀刻出一片压力膜片。压力膜片上有个压电电阻应变片,组成一个惠斯顿电桥。

1、差压变送器的几种应用测量方式:
(1)与节流元件相结合,利用节流元件的前后产生的差压值测量液体流量。
(2)利用液体自身重力产生的压力差,测量液体的高度。
(3)直接测量不同管道、罐体液体的压力差值。
2、差压变送器的工作原理:
差压变送器能将接收的气体、液体等压力信号转变成标准的电流电压信号,以供给指示报警仪、记录仪、调节器等二次仪表进行测量、指示和过程调节。
来自双侧导压管的差压直接作用于变送器传感器双侧隔离膜片上,通过膜片内的密封液传导至测量元件上,测量元件将测得的差压信号转换为与之对应的电信号传递给转换器,经过放大等处理变为标准电信号输出。
