Vega TD-21 is designed to take readings from an external temperature sensor (included in delivery) with subsequent accumulation and transmission of this information to the LoRaWAN® network. The device can communicate both with a given period and when the measured temperature goes beyond the established limits. The explosion-proof design allows the device to be used in production areas of enterprises where the formation of mixtures of air with gases and explosive vapors of substances is possible.
Vega TD-21 has an external battery pack and a backup power source inside the main body. This design option allows you to replace the main power source without opening the case or dismantling the device from the monitoring site. When replacing the main power source, the device will continue to operate using a backup battery.
