国产好点的压力变送器|420ma压力变送器-华恒变送器厂家微差压型压力变送器的基本原理是：将一个空间用敏感元件（如膜盒）分割为两个压室，即正压室和负压室；分别向两个压室中引入压力时，传感器在正压和负压的共同作用下，产生一定的位移或者位移的趋势，这个位移（位移趋势）与两个压室的压力差成正比，通过内部转换电路将位移量转换为反应差压大小的标准的信号输出，通常输出的信号为标准的4～20m A电流信号。

国产好点的压力变送器|420ma压力变送器-华恒变送器厂家在实际构造中，敏感元件的结构、转换方式、标准信号等都有很多种。结构方面：有电阻应变片、压阻式、电感式、电容式、谐振式等，但一般情况下都采用压阻式微差压型压力变送器，因为它具有价格低、线性好、便于维修、迁移量大、较高的精度等特性。转换方式：根据采用不同的传感器会有不同的转换方式，但可以肯定的是终都是转换为电信号。标准信号：在目前生产中有电流信号、电压信号两种，通常采用的是4～20m A电流信号。

The basic principle of micro-differential pressure transmitter is that a space is divided into two pressure Chambers (positive pressure chamber and negative pressure chamber) with sensitive elements (such as diaphragm). Respectively to the two pressure chamber pressure, is introduced into the sensor in the positive pressure and negative pressure, under the joint action of produce certain displacement or displacement trend, trend (displacement) and the displacement is directly proportional to the pressure difference of the two pressure chamber, through internal conversion circuit converts displacement response differential pressure standard signal output, and the size of output signal usually for 4 ~ 20 m A standard current signal.
In the actual construction, there are many kinds of sensor structure, conversion mode, standard signal and so on. Structure: resistance strain gauge, piezoresistive type, inductance type, capacitive type, resonant type, etc., but generally used piezoresistive type differential pressure transmitter, because it has low price, good linearity, easy maintenance, large migration, high precision and other characteristics. Conversion mode: there will be different conversion modes depending on the use of different sensors, but it is certain that they will eventually be converted into electrical signals. Standard signal: there are two kinds of current signal and voltage signal in current production, which are usually 4-20m A current signal.
