Wireless radio transmitter RDT-4000 series

radio data transmissioncontrolrelative humidity, temperature and light

The RDT-4000/... Series are radiotransmitter devices to transmit measures or signals from remote places up to the central control, by means 868 MHz (915 MHz in USA) free band radio, from 100 mW up to 500 mW power transmit allowing long ranges with high gain antennas. These devices can be used to transmit up to two-signals per module, with 250 modules max. in peer-to-peer mode or multipoint mode. The basic applications are in wireless communication of temperature probes or any other, field transmitters, etc., with PC, PLC systems or controllers used in industrial processes. Relative Humidity, Psychrometric Humidity, Absolute Humidity, Dew Point, Enthalpy Several versions are available to measuring and to transmit these signals: - Specific Version for RH with enclosed probe - Specific Version for RH with separate probe - Specific Version for Psychrometric RH by means Dry-Wet bulbs - Specific Version for Absolute Humidity, Dew-Point and Enthalpy by psychrometric calculus
