Honeywell DR4300 Circular Chart Recorder
What is it
The DR4500 circular chart recorder is a microprocessor-based recorder suitable to meet a wide range of industry requirements. It comes with a digital display and easy-to-use operator interface, and is available in many models to cater to the specific needs of different applications such as flow and HTST dairy processes. The Truline pen provides a convenient method to document a process while minimizing maintenance hassles. An integral PID controller and RS-485 Modbus communications ensure user empowerment. This accurate and easily configurable recorder is designed to work in tough industrial situations.
How does it work
Honeywell Truline circular chart recorders accept directly connected process signals which allow them to process data and create the chart under actual environmental conditions, eliminating the risk of temperature and humidity expansion of the paper and enhancing its accuracy. The chart recorders use single or dual pens or a hot-stylus type pen to produce the chart image. The simple design of these chart recorders makes them easy to operate even by inexperienced operators, and the modular construction makes them easy to maintain, modify and service. The bright, digital display and a dedicated configuration keypad bring further convenience to the user. These chart recorders come with NEMA 3 or NEMA 4 front face protection, making them suitable for tough production environments.
What problems does it solve
The DR4500 circular chart recorder eliminates the need to purchase individual circular charts for each application with its single circular chart requirement, thereby enabling cost savings to the user through reduced stocking of multiple circular charts.
