A powerful duo
Wireless communication for near and far
License and registration free industrial radio bands lend themselves well for wireless transmission of signals over short distances. But for large distances, one usually cannot get around using modems in conjunction with GSM/GPRS technology. VEGA has two components, PLICSRADIO and PLICSMOBILE, that make customized and thus cost-effective wireless communication solutions possible.
PLICSRADIO wirelessly transmits 4 ... 20 mA/HART signals as well as switching states up to one kilometre in the 2.4 GHz radio band. The solution lends itself well in cases where laying a signal cable from the sensors to the signal conditioning instruments is not possible or too ex-pensive. It overcomes obstacles such as railroad tracks or rivers quickly and cost-effectively. Further areas of application are mobile system components. With the flexible PLICSRADIO, not only can existing systems be quickly and easily extended without interruption, but modifications can be carried out any time as well.
VEGA has been using remote data transmission in conjunction with signal conditioning instru-ments for years. These supply the sensors, deliver intrinsically safe signals when required and ensure that standard modems (analogue, ISDN or GSM/GPRS) can be accessed.
The transmitting and receiving unit PLICSMOBILE fits seamlessly into VEGA"s modular plics® concept. It is available either as an integrated auxiliary module for the new plics®plus sensors or as a standalone instrument.
SIM card and integrated modem allow worldwide data transmission via the widely-used GSM/GPRS service – including remote diagnosis and teleservice. Another plus: the integrated energy management system with independent battery supply.
PLICSMOBILE complements the solutions with signal conditioning instruments especially in the area of VMI (Vendor Managed Inventory). Areas of use are primarily applications in which measurement and evaluation are located far apart, e.g. deep wells, high containers or mobile silos.
