Circular Chart Recorders

Product Overview

The Circular Chart recorders offer a cost-effective way to maintain these records and help manufacturers optimize the data collection process. The recorders are microprocessor-based and can record a variety of process parameters such as temperature, humidity, pressure or flow from transmitters.

ARC 4100

A general purpose, analog, one or two pen, 10" circular chart recorder capable of measuring and recording process variables from a variety of inputs types. Recorders are available with optional limit device or controller capability. Available with 12, 24, 48, or 72 hour, or 7 day rotation times and over 60 ranges. Can be panel or surface mounted.

Standard Features

Various inputs types available: thermocouple, mV, V, and mA
Sensor break protection
Disposable fiber tipped pens: red, green

MRC 5000

The best value available today for simple recording. A low cost, general purpose, microcontroller based, one or two pen, 10" circular chart recorder available in two versions; basic recorder and limit recorder. Simple 3 button operation and configuration. Slim 2.5" panel depth and 3.8" overall depth makes it ideal for panel or surface mounting.

Standard Features

4 Digit display
Universal sensor inputs: thermocouple, 3 wire RTD, or DC linear (mA, mV, V)
2 Programmable alarms per pen
Chart speeds: 8, 12, 24, and 48 hours, and 7 days
Disposable fiber tipped pens: red, green
90 to 264V AC powered

MRC 7000

A general purpose, microcontroller based, one or two pen, 10" circular chart recorder available in four versions; basic recorder, limit recorder, recording controller, and recording profile controller. The controller is capable of controlling any process from simple on/off to dual 4-20mA outputs with full PID on both pens. Can be panel or surface mounted.

Standard Features

4 Digit display per pen
Universal Isolated sensor input: thermocouple, RTD, mA, mV, or V
Chart speed from 0.1 to 999.9 hours
Disposable fiber tipped pens: red, green

MRC 7700

A special purpose instrument with an algorithm to automatically calculate relative humidity from wet bulb and dry bulb temperatures. A microcontroller based, one or two pen, 10" circular chart recorder, available in three versions; basic recorder, recording controller, and recording profile controller. The controller is capable of controlling any process from simple on/off to dual 4-20mA outputs with full PID on both pens. Can be panel or surface mounted.

Standard Features

Selectable process value display for each pen: wet bulb, dry bulb, or RH.
Compensation for barometric pressure changes
4 Digit display per pen
Universal Isolated sensor input: thermocouple, RTD, mA, mV, or V
Chart speed from 0.1 to 999.9 hours
Disposable fiber tipped pens: red, green

MRC 7800

A special purpose, microcontroller based, one or two pen, 10" circular chart recorder for flow applications with an 8 digit display to totals. Input capabilities include millivolt, volt, and milliamp. On one pen units, two displays are available so the total can be continuously displayed in addition to the process variable. On two pen units, the unit can be configured to combine the flow rates and totals for display and preset usage. Can be panel or surface mounted.

Standard Features

8 Digit display per pen
Isolated linear sensor input: mA, mV, V
Square-root extraction
Variable exponent for weirs and flumes
Custom curves for flow correction, linearization, of height to volume conversion
Pressure compensated DP flow calculation
Adjustable flow time base - per sec, per min, per hr, and per day
Chart speed from 0.1 to 999.9 hours
Disposable fiber tipped pens: red, green

MRC 8000

A general purpose, microcontroller based, one or two pen, 12" circular chart recorder available in two versions; basic recorder and recording controller. The controller is capable of controlling any process from simple on/off to dual 4-20mA outputs with full PID on both pens. Can be panel or surface mounted.

Standard Features

4 Digit display per pen
Universal Isolated sensor input: thermocouple, RTD, mA, mV, or V
Chart speed from 0.1 to 999.9 hours
Glass window with NEMA 3 enclosure
Disposable fiber tipped pens: red, green

Versachart

The world's first circular chart recorder that prints brilliant 4 color trend lines, scales, and alphanumeric data on plain paper charts. All time lines are printed straight, rather than curved, and printed on even time intervals for improved readability and easy time determination. All trend lines are synchronized; no drag pen time offsets. Brilliant, easy to read, 40 character vacuum fluorescent display shows values in a variety of user configurable formats. Available in two versions; basic recorder and recording controller. The controller is capable of controlling any process from simple on/off to dual 4-20mA outputs with full PID on up to 4 loops.

Full English prompts and parameter selection by English choices makes this instrument easy to configure. From simple recording to sophisticated applications, merely use the set of features you need to provide the solution.

Standard Features

Place trend scale on any portion of the chart
Magnify any portion of the trend scale
4 alarms per pen
Event driven display messages and/or printed chart messages
Configurable logic equations for PLC like capability
Configurable operator inputs for digital state changes via the keypad and display
Choice of 10", 11" or 12" charts
Chart speed from 6 to 9999 hours
Disposable 4 color cartridge is changed in seconds
Colors: red, green, blue, and black
Can be panel or surface mounted
Configurable from an IBM PC compatible
90 to 264V AC powered
