VW Data Recorder

VW Data Recorder

Applications

The VW Data Recorder is a recording readout for pluck-type vibrating wire sensors, RTDs, and thermistors. Simple to operate, the Recorder stores up to 2000 readings and can transfer them to a PC for processing with a spreadsheet.

Overview of Operation

To obtain a reading, switch on the power, connect sensor signal cable to the Recorder’s panel-mounted binding posts, and press the Enter key. To record a reading, press the Enter key a second time. Each reading is identified by date, time, and an ID number.

You can choose frequency units (Hz or Hz squared), sweep frequency, RTD or thermistor, and ID numbers from 0 to 31. There is also a microstrain mode for use with Slope Indicator’s spot-weldable strain gauge.

To transfer readings to your PC, connect the serial interface cable between the recorder and the PC, and run the Data Recorder Manager program. Specify a file name and location for the data, and two mouse clicks later, the data is on your PC, ready for your spreadsheet program.

VW Data Recorder

Advantages

Wide Compatibility: The VW Data Recorder reads any pluck-type VW sensor.

Simple Operation: Learn how to use the VW Data Recorder in just a few minutes. Most operations are performed by pressing a single key. Data retrieval is just as easy.

Reliable: Readings are stored in secure, non-volatile memory that keeps data even when batteries are fully discharged.

Spreadsheet Friendly: The Windows-based Manager program retrieves readings and stores them in ASCII file, ready to open and process with your spreadsheet program.

No Setup: The VW Data Recorder is always ready to use. There are no sensor lists or calibration factors to load.

No Special Parts: The VW Data Recorder uses standard cables and batteries. Built-in terminals eliminate the need for a jumper cable. The serial interface cable can be replaced at any computer store, and the standard D-cell batteries eliminate the need for a charger.
