Reduced price compact standalone
data-loggers
A compact and reliable eight-channel 12-bit data logger developed originally for undersea applications is now available at a reduced price of only GBP800 in one-off quantities
The 2HDL8, a compact and reliable eight-channel 12-bit data logger developed originally for undersea applications at depths (in a suitable housing) to 3000m, is now available from Celsum Technologies at a reduced price of only GBP800 in one-off quantities, less than half its original price This price cut has been possible because of economies of scale permitted by manufacture in greater numbers

New strain gauge amplifier housing from Celsum
The new ILE is a compact, robust, precision-engineered, stainless steel EMC-shielded housing that will accept either an InCell analogue strain gauge conditioning amplifier or a DCell digital converter
The data logger may be used in "stand-alone" mode, where it can 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 printed circuit board measuring only 50 x 320 mm, is available with a choice of onboard memory of 128 or 256 Mbyte.
The 2HDL8 is configured prior to deployment using a computer and the supplied software, and, similarly, data is downloaded and displayed after recovery using a computer.
A whole range of sensors may be accommodated, for example temperature sensors, inclinometers, strain gauge devices (eg pressure, tension, load), single- and multi-axis accelerometers, magnetic direction and so on.
As long as an analogue signal of 2.5V full scale can be supplied to the recorder, the data may be monitored.
The sampling rate is programmable between 2 and 30 Hz, 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 four channels with 128 Mbyte of memory onboard would allow 24 days of continuous logging, 460 days at 20 minutes logging every 6 hours, and 600 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, and is suitable for research and development projects as well as for incorporating into other products by OEMs.
