Data logger breaks free from cables
A
dataTaker product story
Edited by the Engineeringtalk editorial team

Bluetooth technology has contributed to a novel data-logging solution in an aggressive environment.
A company specialising in the manufacture of precision glass-fibre mouldings found that the temperature monitoring of semimobile glass-fibre mouldings during the curing process has in the past posed problems of safety and possible cable failure.
Previously, the communication links between the data logger and the host PC were hard-wired Ethernet connections, resulting in trailing cables which can be hazardous, or may break causing loss of communications.
This problem has been resolved by Integrated Data Logging Solutions (IDLS) which provided it with a Bluetooth wireless communication solution; converting the existing hard-wired Ethernet links to wireless system.
The data is transmitted from the Datataker DT600 series data loggers to a host PC enabling the cure process to be monitored in real time and production of reports for quality maintenance, without the hazard of cables trailing the factory floor.
The glass-fibre moulds can be moved safely, concurrently monitored, without danger to operators or equipment, or failure of the temperature measurement system.
The Datataker DT600 series data loggers with DeLogger software and remote alarm systems are frequently used in the manufacture of glass-fibre and plastic products.
The combination of the Datataker system and Bluetooth communications can now solve possible problems where hard wired systems can be a danger.
The DT600 system has up to 10 differential or 30 single-ended analogue channels, seven digital and counter channels, expansion port for up to two expansion modules each with 10/30 analogue channels.
This model features a keypad and display for current data, alarm states and macro programming and has an alarm beeper.
Most sensor types can be connected without needing additional signal conditioning.
The number of data points that can be recorded is approximately 165,000.
Replaceable lithium back up batteries ensure that no data or programming is lost due to low battery or power failure and SRAM PC card memory support can be upgraded to 4Mbyte for greater flexibility and improved speed of operation.
Upgrading Flash memory firmware can be performed direct from the PC for convenience and time saving.
All Datatakers are straightforward to program using the supplied software, they provide time or event monitoring of sensors and make instantaneous measurements.
Statistical and other calculations such as average, standard deviation, maximum or minimum and apply internal sensor calibration can also be carried out.
