德国Sartorius PR1591模拟信号变送器可以对电流、电压等电量参数或温度、电阻等非电量参数,进行高速精确测量,经隔离转换成标准的模拟信号输出。既可直接与指针表,数显表相接,也可以与自控仪表(如PLC)、各种A/D转换器、以及计算机系统配接。
The analogue transmitters of the PR1591 series from Sartorius have been especially designed for use in industrial environment, and are particularly suited for applications with hazardous areas (zone 1) like chemical, petrochemical and food industries. The applications range from level control and simple weighing to complex applications e.g. mixing and filling stations, in conjunction with PLCs, computers or other supervisory systems.
