GR33U2  Power Line Monitoring  Recorder & Data Logger

GR33U2 Power Line Monitoring Recorder

The GR33U2 Power Line Monitoring Recorder with its selection of signal conditioning inputs (Voltage, Frequency), offers reliable, low-maintenance, thermal array recording technology.  The high resolution thermal head has a printing width of 296 mm (11.65 inches) with 8 printing elements or dots per mm (203 per inch).  The grid is printed simultaneously with the signal waveforms, eliminating any drift between waveforms and grid.

The analog section has a 16 bit A/D converter per channel which is self calibrating, ensuring high accuracy and long term stability.

Alphanumeric labeling of the traces and chart can be readily entered from the keyboard, terminal or computer.

The operation of the recorder is controlled by a unique and compact control panel. A single rotary control scrolls through the recorder menus, allowing the user to quickly alter items such as chart speed and grids. This technique eliminates the numerous front panel controls usually found on this type of recorder

Alternatively, the recorder can be controlled externally by a host computer or by a PC using the optional PC33 Control and Interface Software.

Also available is the DISP33 Virtual Chart Recorder Display program that graphically displays data from the recorder in real-time.  The program uses an PC  to create a display that resembles the output of the chart recorder - vertical traces on the chart.

This results in a versatile, accurate, reliable and low maintenance recorder with a wide chart presentation, with high resolution and easy viewing.

Data Logging

In addition to producing hard copy, the recorder may also be operated in a logging mode where data for up to 320 days is kept in battery-backed memory. The log data is tagged with time, date and "Station I.D.".  The data may be periodically retrieved on a daily, weekly etc. basis by an external computer with a standard RS232 port or via a modem.

Remote Real-Time Monitoring

The trace data can be transmitted by the serial port or a modem to a remote host computer for monitoring or recording.  The transmission interval is user selectable.

Both the data logging and real-time outputs will operate with or without paper recording.  In addition, these two features have a simplified command set and status alarms provided for the host computer.
