| 變送器，顧名思義，變送器含有“變”和“送”之意，下面我們分別介紹一下“變”和“送”的原理。 |
| 所謂“變”，是指將各種從傳感器來的物理量，轉(zhuǎn)變?yōu)橐环N電。比如：利用熱電偶，將溫度轉(zhuǎn)變?yōu)殡妱?shì)。由于電容易處理，所以，現(xiàn)代變送器，均將各種物理，轉(zhuǎn)變成電。 |
| 所謂“送”，是指將各種已變成的電，為了便于其他儀表或控制裝置接收和傳送，又一次通過電子線路，將傳感器來的電，統(tǒng)一化。 |
| 這種“變”+“送”，組成了現(xiàn)代常用的變送器。比如：SST3-AD是一種將電流互感器的輸出電流，轉(zhuǎn)變成的4-20MA的電流變送器;再比如：SST4-LD，可以將重量傳感器來的重量，轉(zhuǎn)變成的4-20MA的重量變送器。 |
