THREE new data loggers will form the centrepiece of the Grant Instruments display on stand F5 at the MTEC 2001 sensing, measurement and instrumentation industry exhibition.
All three universal logger models measure inputs from a variety of sensors and are ideal for use in industrial, scientific, research and environmental applications. Each can be used as a portable meter, standalone data logger or in a PC-based data acquisition system. All loggers can be set up in an easy-to-use spreadsheet format that allows instant data analysis. No programming skills are required.
The Squirrel SQ400 and SQ800 feature four and eight universal inputs respectively, while the SQ1600 boasts 24. In each case, the choice of universal input avoids application redundancy and allows connection of thermistors, thermocouples, voltage, current (4-20mA) and resistance. Each input type is software selectable.
Additionally, the SQ1600 is an intelligent logger which can scan sensors, take instantaneous readings and initiate actions when a channel exceeds pre-set limits. All the new loggers are remotely operable via GSM, PSTN radio or satellite modem links.
The new loggers become stable-mates to the successful Grant SQ1000 range, and their launch coincides with a major refocus of the Cambridgeshire-based company. Following recent reorganisation, Grant now has two distinct divisions, one concentrating on the development and manufacture of data loggers and the other on its popular and innovative range of laboratory equipment.
New Squirrel OQ606 Oven Logger offers unmatched value and ease of
use
Grant Instruments introduces a new oven logger which features a low profile
- just 21mm - to suit a wider range of ovens and applications. It is designed
for ease of use, providing a maximum of information with a minimum of
button pushing.
The
compact Grant OQ606 can be quick-started
by pressing a single button, when it assumes a default setting which will
meet most requirements. Programming other set-ups via PC is also simpler
than ever before, using the friendly features of Grant's software environment.
Flexible triggering functions allow logging to be initiated by rate of
rise of temperature, pre-set temperature thresholds, or duration of run.
The logger can
be programmed to perform cure calculations, and to output both profiles
and cure results directly to a printer, with no need for a PC.
The Grant OQ606 logs data from up to six K-type thermocouples, immediately indicating which channels are active on an easy to understand alphanumeric display to reassure the user that sensors are operating correctly to avoid wasted runs. It measures temperatures up to 1300°C with up to ?.5ºC accuracy and 0.1°C resolution. Logging can be programmed to record up to 8 samples per second to every 2 hours, on all channels.
On completion of a run, temperature and cure information is downloaded in seconds at the press of a button, to either a portable printer or PC. Flash memory supplies battery-fail protection for eight runs, typically one day's work.
The competitively priced Grant OQ606 package includes logger, set up software, and Paintwise Lite basic analysis software. Paintwise Lite provides set-up and download functions, storage of user settings, data in tabulated or graphical formats, basic report functions, cure specs and calculations, and export of data in ASCII format. Users can upgrade to the power of Grant's Paintwise Plus analysis software for advanced data analysis. A portable printer can also be supplied as part of the package, and Grant has designed new ranges of clip-on and magnetic probes to accompany this logger, to provide a total solution for oven monitoring.
Indeed, the broad range of data loggers available from Grant enables users to find solutions for a wide variety of paintshop applications, including emissions monitoring, humidity monitoring, etcetera.
New versatility for data capture from Grant
Grant Instruments introduces an expansion to its popular Squirrel data logger range. In the Squirrel 1600, input capacity is increased to 24 single-ended or 16 differential channels, providing new flexibility for data capture and analysis. There are eight relay and FET outputs for generating alarm and control signals.
With high-capacity non-volatile flash memory and PCMCIA capability, the Squirrel 1600 is capable of storing a high volume of information. To ensure that memory space is allocated only to relevant data, logging is subject to a wide range of internal and external triggers.
Logging at up to 60 samples per second can be initiated by user-defined channel thresholds, digital states, timeclock or logger system events. Multi-condition triggers can be programmed and can set the logger to start, stop, pause or continue the run, take a defined set of readings, change sample rate, or trigger a control or alarm output.
Set-up of these versatile facilities is straightforward, using new Windows-based Setwise software supplied free with the data logger.
Information can be downloaded to a PC either locally or via modem for analysis and reporting, with facilities for serial or parallel combination of multiple data files. Data manipulation includes statistical functions, calculations and sensor calibration. Multi-channel, on-line colour graphs and bar-charts highlight cause-and-effect correlations, with value readout from the cursor position. Alarms and events are also highlighted.
Rugged, compact and battery powered, the Squirrel 1600 copes with the toughest conditions on the factory floor, in vehicle, or in the field. It is easily upgraded in firmware to provide expanded measurement, control and data storage capabilities as the application requires.
The Squirrel 1600 captures data from a very wide range of sensors, transducers and meters. Providing a total on-line metering and data logging solution with capability to control switches, valves and other actuators, it addresses a wider range of applications in:
