壓力開關的傳輸信號
當用戶在購買壓力開關時，可能都會問到壓力開關的信號輸出類型，今天小編就為大家介紹壓力開關的傳輸信號。
一般情況下，壓力開關的模擬輸出信號都是4-20mA的，4～20mA的電流環是指，4mA表示最小電流信號，而20mA則是指信號的滿額度---最大電流信號，當壓力開關的信號低于4mA高于20mA時，就代表了測量出現異常，壓力開關會發出報警。4-20mA的信號有兩種類型：二線制和三線制。二線制是指兩根電流傳輸線；三線制則是指供電電源除了兩根電流傳輸線還有第三根線，在無特殊情況下，壓力開關使用的一般都是三線制的。總之，這兩種類型都可以準確有效的反映信號的大小，用戶可以根據自身實際需求進行選擇。
