中国 温度变送器 结构组成与应用介绍
一体化温度变送器具有结构简单、节省引线、输出信号大、抗干扰能力强、线性好、显示仪表简单、固体模块抗震防潮、有反接保护和限流保护、工作可靠等优点。
一体化温度变送器的输出为统一的4～20mA信号；可与微机系统或其它常规仪表匹配使用。也可用户要求做成防爆型或防火型测量仪表。
呵呵 一体化温度变送器 一般由测温探头(热电偶或热电阻传感器)和两线制固体电子单元组成。采用固体模块形式将测温探头直接安装在接线盒内，从而形成一体化的变送器。一体化温度 变送器 一般分为热电阻和热电偶型两种类型。 下面来做介绍
哇1热电阻温度变送器是由基准单元、R/V转换单元、线性电路、反接保护、限流保护、V/I转换单元等组成。测温热电阻信号转换放大后，再由线性电路对温度与电阻的非线性关系进行补偿，经V/I转换电路后输出一个与被测温度成线性关系的4～20mA的恒流信号。
哇2 热电偶温度变送 器一般由基准源、冷端补偿、放大单元、线性化处理、V/I转换、断偶处理、反接保护、限流保护等电路单元组成。它是将热电偶产生的热电势经冷端补偿放大后，再帽由线性电路消除热电势与温度的非线性误差，最后放大转换为4～20mA电流输出信号。为防止热电偶测量中由于电偶断丝而使控温失效造成事故，变送器中还设有断电保护电路。当热电偶断丝或接解不良时，变送器会输出**值(28mA)以使仪表切断电源。 SIEMENS ITE CIRCUIT BREAKER 40 AMP 480V3 POLE HED43B040
