http://www.pu-shengyb.com/

 1、特點     現場顯示溫度，直觀方便；
                                    具有自動切斷電源和報警功能；
                                    安全，使用壽命長；
                                    多種結構形式，可滿足不同要求

                                2、工作原理
                                   
                                電接點雙金屬溫度計是利用溫度變化時帶動觸點變化，當其與上下限觸點接觸或斷開的同時，使電路中的繼電器動作，從而自動控制和報警。
