Metmotec, a British specialist metering modem supplier, has launched modems for harsh environments. The Endurance range has both PSTN and GSM modems powered either by mains or batteries and aimed at industrial and field applications with particular focus on industrial electricity meters used in substations. The GSM modem can provide GPRS operation with fixed-IP address SIM cards.
The new modems are complete ‘systems’ supplied in IP65 rated enclosures of very tough ABS material providing protection against rain, dust, sunlight and insect ingression; they can operate from minus 20 degrees to plus 70 degrees Celsius. Each system is contained within the enclosure and comprised of modem, power source, host meter or terminal device interface adapter, and antenna for the GSM version.
