霍尼韦尔 DR4500 圆图记录仪将笔绘模拟迹线的简单性与微处理器控制功能的复杂性相结合。这种组合造就了用户可配置的记录仪，可轻松适应从高炉到实验室的各种应用要求。

除了记录模拟迹线外，Classic 系列记录仪还连续显示所选工程单元中的过程变量值。

单笔和双笔型号均接受来自可配置范围限制内各种传感器或变送器中的任何一个的输入。此外，型号还配有一个或两个数字控制器，以生成受控输出信号，以操作阀门、阻尼器、加热元件等进行过程控制。

Features:
Record up to four process variables on the same timeline
digital display
Fiber optic pen tip

The Honeywell DR4500 circular chart recorder combines the simplicity of pen drawn analog traces with the complexity of microprocessor control functions. This combination creates a user configurable recorder that can easily adapt to various application requirements from blast furnaces to laboratories.

In addition to recording simulated traces, The Classic series recorders also continuously display the process variable values in the selected engineering units.

Both single and double pen models accept input from any one of various sensors or transmitters within the configurable range limit. In addition, the model is equipped with one or two digital controllers to generate controlled output signals for process control of valves, dampers, heating elements, etc.
