LM-T-PRO RF Series Wireless Data logger

Data Logger | LM-T PRO RF

The LM-T-PRO RF series of wireless data logger is a new RF based data logger that measures temperature and transmits data using Radio Frequency to eliminate clumsy and time-consuming wiring requirements. These data loggers are very useful in monitoring data across large facilities as they do not require any wiring. Deployment is very quick and easy. Data are sent by each device directly to the centralized broker (repeater) device and from there to gtekNetTM software over ethernet port. These data can be accessed from any network connected device using standard web browser.

The data logger consists of RF radio transmitter and receiver operating at 869.88 MHz (SRD License Free: EU Version) frequency. These data loggers form a star network with its broker. The broker is connected to the client-server based gtekNetTM software through ethernet. A new data logger when it is in the range of the central node – broker, gets connected to the gtekNetTM. Each device transmits its data to the broker and is captured in gtekNetTM. Any parameter of the data logger when set / changed from gtekNetTM, first goes to the broker and then to the device. These data loggers have an internal memory of 3000 data sets. In the event of communication failure between broker and device or broker and gtekNetTM, after reconnection, all the missed data will be synchronized by gtekNetTM automatically. This ensures that no data is missed.
