Numerous applications for eight-channel, 12-bit device developed for undersea applications at depths of up to 3000 metres
Magna Projects and Instruments is adding a compact and reliable state-of-the-art modular datalogger to the list of products it distributes.
The 2HDL8 is an eight-channel, 12-bit device which was developed for undersea applications at depths (in a suitable housing) to 3000 metres.
The datalogger may be used in 'stand-alone' mode, where it may be left in situ for several months, then recovered and the data downloaded and processed, or else the logger may be configured in 'hard-wired' mode and periodically interrogated by a host computer.
The instrument, which is supplied on a circuit board 50mm x 320mm, is available with a choice of on-board memory of 64MB, 128MB or 256MB.
A whole range of sensors may be accommodated, for example inclinometers, strain gauge devices (eg pressure, tension, load), temperature sensors, single- and multi-axis accelerometers, magnetic direction etc.
The sampling rate is programmable between 2 and 30Hz, and the system has a programmable start and may be programmed to 'sleep' between bursts of high-speed data recording.
As an example of duration with different logging profiles, scanning 4 channels with 64MB of memory on board would allow 12 days of continuous logging, 230 days at 20 minutes logging every 6 hours, and 300 days at 20 minutes logging every 2 hours.
The 2HDL8 has a wide range of applications in the laboratory, on process plant and in the field.
Said director Roy Carter, "These compact dataloggers complement our other product ranges of signal conditioning equipment and laboratory instruments.
We are sure that there are many diverse applications for them."
