变送器种类很多,总体来说就是由变送器发出一种信号来给二次仪表使二次仪表显示测量数据。将物理测量信号或普通电信号转换为标准电信号输出或能够以通讯协议方式输出的设备。一般分为：压力变送器，差压变送器，液位变送器，电压变送器,电流变送器，电量变送器，流量变送器，重量变送器，温度变送器,湿度变送器等等。
压力变送器是工业实践中最为常用的一种传感器，其广泛应它能将测压元件传感器感受到的气体、液体等物理压力参数转变成标准的电信号（如4~20mADC等），以供给指示报警仪、记录仪、调节器等二次仪表进行测量、指示和过程调节。用于各种工业自控环境，涉及水利水电、铁路交通、智能建筑、生产自控、航空航天、军工、石化、油井、电力、船舶、机床、管道等众多行业。
