Warehouse and Coolroom mapping

The key to maintain the desired temperature or temperature/humidity in the store or warehouse is being able to know what is happening, when  and where . Constant values are hard to maintain in large open spaces.  During the year the conditions change in the environment, so it is important to keep an eye on the temperatures.  Many factors influence temperature fluctuations:

    1. Outside temperatures, sun and wind
    2. Temperature bridges in the construction
    3. Location of inlet and return air
    4. Placing and size of fans
    5. Shelving and pallets
    6. Doors and loading docks
    7. Intake of warm product
    8. Warm air moving upwards

For the best understanding of temperature and humidity movements , it is necessary to monitor the area using a number of data loggers.  How many loggers are needed, depends  on the size and height of the area and the kind  product stored. It may desirable to monitor in two or three levels.

Using wireless T-TEC Data loggers has the advantage that once the loggers have been placed permanently,  they will stay in place and report back to the computer. The wireless data loggers  can send real time temperature updates as well as file downloads.  They will need  new batteries only once a year in normal use: Logging every 15 minutes with automatic reporting of actual temperatures once an hour and file downloads each week.  

The files are seamlessly collected in the database in the computer.  It is also possible to send the files to the cloud. The data loggers can send alarms to the computer, if a minimum and maximum temperature level has been set.

Setting up the system is easy, as there is little or no wiring needed. The data loggers can be fastened to a wall bracket, hung or just put on a shelf.  The transmission from all  the data loggers goes via radio to one or more gateways.  In a warehouse it may be necessary to have more than one gateway  to contact all the loggers. Larger antennas may also do the trick,
Each gateway needs to be connected to a mobile phone charger for power. The easiest way to communicate with the gateway/s is via WiFi or wired LAN to the PC or the internet.

When planning the layout of the data loggers, it is helpful the make an imaginary grid of rows, columns and layers. When starting the data logger, the specific location should be entered in the location field, for instance R1C2L3. The logger is then marked with this location, to make sure it is placed in the right spot - it also a good idea to label the spot with the data logger number.  Using DyMap Software it is then possible to combine the readings from all the loggers for a chosen period into a map of moving colours, which clearly show how the temperature changes over time. Files can also be imported into spreadsheets.

T-TEC Data loggers are made to the highest standards and accuracy. The casing is sturdy and durable and of food grade plastic. There are many models to choose from, with or without display, internal or connected sensor, internal or external antenna.  
Temperature Technology offer NATA traceable calibrations and replacement of batteries at a very reasonable price.
