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”,就是指將各種從傳感器來(lái)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(lái)的電,統(tǒng)一化。 |
這種“變”+“送”,就組成了現(xiàn)代常用的變送器。比如:SST3-AD就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(lái)的重量,轉(zhuǎn)變成的4-20MA的重量變送器。 |
