GRAPHTEC LEGACY PRODUCTS

Western Graphtec developed premier linear chart recorders, pen oscillographs, and thermal array coders that provided paper records for electronic signals in both data acquisition and signal analysis. Graphtec’s legacy chart recorders were considered leading recorders that carried paper options for oscilloscopes carrying 0Hz to 10Khz signals. Application varied from sound, vibration, phase shifts, velocity, acceleration, brain waves, magnetic force, and even animal heart beats. 

Carrying military-grade precision and performance that matched leading electronic testing products of the day, Graphtec’s WR linear chart recorders and WX X-Y recorders have proven to offer the data that industry professionals trust day in and day out. Many of these products are still being used fully in line in aerospace, medical, and military applications. Some are used to secure your next flight with strain testing for airplane wings. Others are used to secure the smoothness of the catheter that goes into your body. 

The strength of the precision and the guiding principals behind Western Graphtec can still be seen in the new line-up of dataloggers and data acquisition platforms that carries our company to this day. Key elements of that principals are: 

  • Channel to Channel Isolation for accurate trust-worthy data for multi-channel applications.

  • Precision High Speed Dynamic Signal Recording

  • Easy to access Data Records

  • Simultaneous and Real Time display and Storage

  • Graphtec GL series of standalone dataloggers can be a great replacement with a digital-based system that provides handy, easy-to-access records that are just as reliable and much more precise .

ABUNDANT SELECTION OF INPUT TYPES TO MEET DIVERSE MEASUREMENT NEEDS

 

REAR PANEL TERMINAL BLOCK

M4 screw terminals have been used for the input terminals to simplify wiring. The terminals can be tightened easily with a screwdriver. If an abnormal value arises, the alarm function informs the operator of the abnormality. Alarm output terminals for four channels are provided as standard.

 

2-TYPES OF HUMIDITY MEASUREMENT ARE ENABLED

USING THE DEDICATED HUMIDITY SENSOR (B-530)

GRAPHTEC MT100 Humidity

DIRECT CONNECTION OF DRY-BULB AND WET-BULB SENSORS

Humidity measurement can be performed by connecting the dedicated humidity sensor to an analog terminal on the MT100 unit.

  • Operating temperature range:-25°C to +80°C

  • Operating humidity range:0% RH to 100% RH.

  • Relative humidity measurement precision:±3% RH (5% RH to 98% RH at 25°C)

  • External dimensions:Φ14 mm x 80 mm (excluding the cable)

  • Cable length:3 m

 

LARGE VOLUMES OF DATA CAN BE DIRECTLY CAPTURED TO

A USB MEMORY STICK OVER A LONG PERIOD OF TIME

 

A USB memory stick is used for the recording medium. A large volume of data measured over a long period of time on the ten available channels can be directly written to and stored on the memory stick. The MT100’s internal memory consists of 14-MB flash media.

 

DATA CAPTURE TIME (WHEN MEASUREMENT IS PERFORMED ON 10-CHANNELS)

Capture interval (sampling speed) 100ms 1s 10s 1min
14-Mbyte internal flash memory Approx. 13 hours Approx. 5 days Approx. 53 days Approx. 323 days
USB memory stick (256 Mbytes) Approx. 9 days Approx. 98 days Approx. 987 days Approx. 5,925 days
GRAPHTEC MT1000 USB Stick

USB MEMORY STICK REPLACEABLE EVEN DURING MEASUREMENT

The USB memory stick can be removed* even while long-term recording is being performed to enable checking of measurement that is still in progress. If the USB memory stick is removed, data capture is switched to the MT100’s internal buffer memory for a period of approximately 10 minutes. When the USB memory stick is reinserted in the MT100, data is once again captured to the memory stick.

* Key operation is required at the time of USB memory stick removal.

WR300 / WR310 SERIES

ARRAY-CORDERS MEMORY RECORDER

 
GRAPHTEC ARRAY CORDERS MEMORY RECORDER WR300 WR310 SERIES
 

The WR310 Series Thermal Arraycorders are economical waveform recorders available in 4, 8 and 16 channel configurations. Unlike old-fashioned paper-only recorders, the WR310 series is a 21st century technology through and through.

Available are convenient 2-channel plug-in modules that adapt the WR300 to a wide variety of input types and sensors, including voltages up to 500 V, strain gages, thermocouples, frequency/RPM signals, and more. There’s also a logic input amp which offers the same number of inputs as the base machine (4, 8, or 16).

Capture data to memory, to the paper, or to the optional hard drive* or PCM-CIA flash RAM memory card. Data are shown all the time of the 8.4″ color LCD screen in a variety of formats, including scroll. oscilloscope, XY, and even FFT! Data can be printed in real time or after acquisition, to the built-in 100 or 200 mm wide chart output.*

Ethernet and USB interfaces are built-in so that you can control the system from your computer (OPS software is included). The same software and interfaces can also transfer data to your computer and convert it to several popular formats, including Excel and delimited ASCII.

WR300 16-channel unit left side – showing 8 WR3 series 2-channel input amps plugged in, plus 4 x 4-ch logic amps (round connectors below)

 

VARIOUS CHART TYPES AND SIZES ARE SUPPORTED

WR300 8 or 16-ch unit with the optional Z-fold paper take-up capability

EASY OPERATION - INTUITIVE CONTROLS

A separate bank of chart speed setting keys enables you to change the chart speed at any time, and four directional cursor keys are provided for easy menu selection. The additional buttons of the WR310 makes this unit even easier to use than similar products. 

WIDE FORMAT PRINTING*

The wide 200 mm (8 inch) paper allows data to be printed with ultimate clarity and precision – even better than what can be shown on the built-in LCD display. 

DATA UPLOAD TO YOUR PC

OPS023 control/transfer/conversion software is included, so you can convert data captured to Excel™ or delimited ASCII format. Need more analysis power? FlexPro™ can open Graphtec data files natively, providing a powerhouse analytical capabilities with an Excel-like interface
