A mains/battery operated RS232 buffer designed to accept data from and communicate with the chartlogger.

It can be used in a number of modes:

• Positioned between the Chartlogger and the PC to provide a large logged data buffer when the PC is turned off or otherwise occupied
• Left in the field attached to a Chartlogger to provide Gigabyte storage capability
• Attached to one or more Chartloggers visited in turn to remove buffered data, which is then returned to the office or laboratory for download

Operation is the same as with a conventional tape recorder with Record, Stop and Play buttons and a display to indicate progress, etc.

It is also available with removable Compact Flash disks where files may be read or copied on a PC running Windows.

The system comprises an 8 analogue and 8 digital channel signal conditioner, data acquisition system and disk buffer in a single enclosure operating like a conventional tape recorder with record and stop buttons. Playback transfers files to the PC. Versions with removable Compact Flash disks are available.

It is designed to trigger and record data from short events that occur at random intervals. In record mode, data is recorded continuously, but will only be saved to disk, as an event , if the signal level of the selected analogue channel exceeds a pre-set level, set via PC setup software. Both the pre- and post-event recording periods can be set, subject to available memory.

Each session is saved to a file in the logger with an incrementing file number. Within each file , there can be single or multiple events.

Powered from external DC source or USB link from PC or hub.

Windows based software allows:

• Setup, calibration and data retrieval via a USB link.
• Utilities for converting the native data files to Excel (.csv), nCode DAC files or other formats.
• Graphics utility that allows an entire file (or portion) to be displayed and saved to a jpeg file suitable for emailing.
• Graphics “copy” and “paste” into other software (e.g. Microsoft Word, Excel, etc).

A group of miniature, low-power data loggers with high level voltage and digital inputs, using removable Compact Flash disks for storage. Simple tape-recorder like operation. The files are directly readable on a PC. Analogue channel counts of 16, 32 and 64 are available, as well as digital channels at 100k samples per second or more. There are extensive trigger facilities for long unattended operation without the need for a PC.

Setup and data retrieval are performed on a PC via a USB link or via the removable disk. This link can also be used to power the system during setup and data download as well as during acquisition, if required.

The PC software runs on any version of Windows 98SE or above. USB support on Windows is required for direct logger communications, although configuration and data files can be exchanged via the removable disk (e.g. NT4). Software utilities are included for configuration, calibration, file conversion, on-line display, etc.

The system comprises a 10 channel K-type thermocouple signal conditioner, data acquisition system and disk buffer in a single battery powered enclosure. Designed for monitoring temperatures during heat treatment processes. Made as small as possible with very low power consumption, even when acquiring data at maximum speed, the logger may be passed through the oven in suitable heat resistant material.

The unit can sample from 1 - 10K samples per second on 10 channels allowing both long term temperature profiles and fast event like quenching to be recorded.

Data is recorded, for a preset number of samples, after a set of trigger criteria has been met. The trigger criteria and record times can be set from the units Windows based software, including trigger delays, defined in terms of number of samples, to reduce the risk of false triggers.

Setup and data retrieval are performed on a PC via a USB link. This link can also be used to power the system during setup and data download as well as during acquisition, if required.

The PC software runs on any version of Windows that supports USB (e.g. 98SE, 2000 and beyond). It contains;

• Utilities for converting the native data files to Excel (.csv) or space separated values in a text file.
• Graphics utility that allows an entire file (or portion) to be displayed and saved to a jpeg file suitable for emailing, as well as allowing the graph to be “pasted” into other software (e.g. Microsoft Word, Excel, etc).
• Channel splitting utility

The system comprises of a signal conditioner, data acquisition system and disk buffer in a single enclosure. There are four strain guage channels with excitation and calibration circuitry. There are also two 4/20mA channels, loop powered by the logger for accelerometer or other sensors with signal conditioning.

Setup, calibration and data retrieval are performed on a PC via a USB link. The unit is powered by either an external battery pack or power supplied via the USB link when it is connected to the PC.

A data logger tailored for twin engine boat/ship use. Four 4/20mA channels, loop powered by the logger for pressure, etc. two RPM channels, digital channels for signals from gearboxes to define ahead-astern and neutral-engaged states. RS232 input accepting and decoding GPS time and positional data.
