microREC

Automatic and autopowerd recording system
 

"microREC" was planned with the scope to realize a multipoint system (without number limitation) with function of reading and automatic digital recording of the measured values of temperature in the range between -40 °C and +85 °C

The system is particularly adapted where it is necessary to get detailed relationship (time-temperature log) of not connectable places (es. pallets, railway, floating, etc.) and/or however not electrically connectable to reasonable costs.

The core of the microREC system is the new Thermochron iButton™ product from MAXIM of advancing technological conception and tried reliability constructed in steel container for heavy duty with dimensions similar to one coin battery and of a total weight of only 3.3 gr.

Every point "microREC" is compost from an internal battery, a temperature probe, a clock and a memory who can store until 2.048 records at programmable intervals and with possibility to choose if to stop the recording after last record or if the new data will cancel first inserted.

Other modifications can be applied on the delay of start, the thresholds thermostats, the date-time, etc.

Every point "microREC" is identifiable with an serial number of 64 bit not ripetibile and not modifiable and with an ulterior Personal Code and a Mission Name modifiable from the software WinmicroREC.

The degree of protection IP68 (with accessory DS9107) allows to use the device under water too.

The transfer of the recorded data to other points adopts the protocol to 1-Wire™ and it can be made on Dedicated Portable Printer (microPRINTER) for the immediate production of printout in GRAPHICAL or TEXT mode or with appropriate adapter connected to a Personal Computer that in union to the software "WinmicroREC" will allows to the user to choose if to change the parameters of every microREC or if to visualize, to analyze ot to archivie the inside stored data in an HD, FD, Cd-rom, etc.

Each tenperature recorder is supplied calibrated already, therefore it is necessary no regulation before using. However it is advisable a periodic control of the precision of the system every two years.
