    TGRF-4101, 1-Channel Temperature Radio Logger for PT100 Probes

    Housed in a rugged waterproof (IP67) case, this self-contained radio logger unit monitors one temperature channel with an optional PT100 probe. 
    PT100 probes measure temperatures from -50 to +300/600°C and thus are a versatile solution for many applications in industy and process technology.
    The data logger is waterproof and suitable for applications in the exterior, in industry and in warehouses.

    Typical applications:
    • Industrial processes
    • Food processing

    The unit will typically run for 12 months on its 2 AA alkaline  batteries. (The 12 months operation is quoted for a typical 10 minute logging interval in a network with max. 25 radio loggers and at max. 25°C operational temperature).
    If required the unit can also be powered by an optional mains power supply.

    The unit is able to transmit logged data to another logger or a receiver and to store data locally in the event of radio contact  being temporarily lost.

    The data logger has got a status LED: 
    + LED off: logger is off
    + green every 4 sec.: everything is o. k.
    + red every 4 sec.: not meshed or battery low or alarm indication

    Please note: This article is only one component of the Tinytag Radio Logger System.
    For proper operation minimum one radio data logger and one Tinytag radio receiver with accompanying software are necessary!
