Also provides guidance during configuration. An eight digit display shows key selected operating parameters. Alternate information displayed during configuration mode. A six digit display dedicated to the process variable. Input Filter: Software: Single pole low pass section with selectable time constants (off to 120 seconds).ĭigital Displays: Vacuum fluorescent, alphanumeric. Sampling Rate: Each input sampled 3 times a second Span Step Response Time: 6 seconds maximum with no filtering Source Impedance: RTD: 100 ohms per lead maximum Input Impedance: 4-20 mA dc: 250 ohms /0-10 Vdc: 200K ohms / All others: 10 Megohms Minimum Input Span: Range is fully configurable with span limitation of the operating range selected. Mechanical Shock Acceleration / Duration: 5g / 30 ms Vibration Frequency / Acceleration: 0 to 200 Hz / 0.2g Relative Humidity: 5 to 90% RH at 40C (104F) Unit is in great condition with minor cosmetic wear from normal use.Īmbient Temperature: 32 to 131F (0 to 55C) Used-was removed from working environment. 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. These chart recorders come with NEMA 3 or NEMA 4 front face protection, making them suitable for tough production environments. The bright, digital display and a dedicated configuration keypad bring further convenience to the user. 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 chart recorders use single or dual pens or a hot-stylus type pen to produce the chart image. 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. This accurate and easily configurable recorder is designed to work in tough industrial situations. An integral PID controller and RS-485 Modbus communications ensure user empowerment. The Truline pen provides a convenient method to document a process while minimizing maintenance hassles. 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 DR4500 circular chart recorder is a microprocessor-based recorder suitable to meet a wide range of industry requirements.
