The Graphtec WR3320A-1D Mark VII Linearcorder/Analog Recorder is a thermal writing pen oscillograph which has been designed to meet the standards required by even the most exacting of professionals, including government agencies all over the world. This is a proud testament to their reliability and legendary performance.
The Graphtec WR3320A-1D Linearcorder Mark VII is capable of recording high-speed phenomena of up to 140 Hz, and can therefore be used for a wide range of applications — from production sites to the laboratory. The Graphtec WR3320A-1D can be configured as a 1 channel recorder with an amplitude of 80 mm.
Continuous Recording Up to 200 Meters
Both roll and Z-fold paper can be used with the Graphtec WR3320A-1D. 100 meter lengths stock inside the recorder, while an optional Z-fold chart supply box with a take-up tray enables the use of 200 meter lengths. Roll paper can be rewound simply by pressing the REWIND switch, and an automatic roll chart take-up unit is available as an option.
Multiple Remote Control Functions
Remote control functions such as pen heat on/off, chart feed start/stop, synchronization with an external pulse, output of paper-end signal, input of event marker signals, and input/output of time marker signals enable automated, unmanned operation.
Seven kinds of remote control functions are available for automation recording and step-up.
- Synchronization chart feed by pulse and voltage signal
- Time mark by timing pulse
- Event mark by event signal
- Pen heat ON/OFF
- Control of chart start ON/OFF, and signal outputfor external equipment
- Paper end signal
- Internal timing pulse output
Optional Versatile Recording and Printing Functions
The Graphtec WR3320A-1D has an optional annotation fuction that prints the date, time (real or elapsed), and chart speed. ASCII codes input from external devices can be used to print alphanumeric and symbols (Direct record and command control record).
Selectable channel variation for various purposes
The Graphtec WR3320A-1D Linearcorder can be configured as a 1 channel 60Hz recorder with an amplitude of 80mm per channel.
0.2% Highly Accurate Chart Feed
The stepper motor and sprocket chart drive eliminate chart wander and enable an accuracy of 0.2%.
1 V d.c. Reference Voltage Output
Rear panel reference voltage output connectors enable easy calibration whenever plug-in units have been exchanged. The reference voltage output used for calibration is 1 V d.c.
Continuous Recording Up To 200 Meters
Both roll and Z-hold paper can be used with the Graphtec WR3320A-1D. A 100m length stock inside the recorder, while an optional Z-hold chart supply box (For 8ch model only) with a chart stock tray enables the use of 200m length.
