Radio telemetry transceiver module DFM 433

RFdata transmissioncompact

The radio devices of the DFM family (DFM 433, DFM-E 433, DFM-EA 433) allow an easy setup of radio paths for the connection of measuring spots to a central data acquisition. They can also be used as a cost efficient alternative instead of a complicated cable setting for example in between the sensor and the data collection station (e.g. water level station). Features and advantages - Setup of autonomous radio networks - No radio allowance necessary - Plug & Play - direct connection of the sensors to DFM - Replacement for cable - input, transmission and output of analogue or digital measuring signals - Serial data transmission without additional effort for protocol - Minimal energy consumption - optimal for solar powered energy supply - Mechanically compact and energy autonomous radio solution - also optimal as upgrade Fields of application As a replacement for cables, the DFM can do the transmission of the measuring data for example of a water level or a discharge measurement from the bridge to the switch cabinet. Similarly the measuring data of wind speed and direction of a wind sensor on a supporting mast of a ski lift can be transmitted to the bottom station. Another example would be the radio data transmission from several automatic weather stations spread over an area to the central data acquisition. For even farther measuring stations, or when unsuitable landforms (mountains) interfere, the measuring data are transmitted over existing stations to the central station (repeater mode). Therefore, the establishment of whole radio networks is possible.
