Description

This Ex-enclosed measurement transmitter can be installed in numerous ATEX environments, such as in oil refineries. At the heart of this innovation is the LoRaWAN CertifiedCM transmitter WLT 310.

The long range and battery life, as well as good immunity from interference, are as before. The new feature is an ATEX-certified casing with applicable antenna isolator. Enclosures are available in single-transmitter (model XD) or four-transmitter (model GUB) versions. The Ex db / Ex tb protection method is applicable in Ex zones 1/21.

One IoTKey® multiuse transmitter can be connected to up to three measuring sensors to read various measurement data, such as temperature and resistance. Other variables can also be read through the mA/V input channel. Naturally, the equipment to be connected must be selected and installed according to the needed Ex classification. The measurement data is sent wirelessly to a gateway device, installed in a safe, non-Ex area – even over long distances and in challenging conditions.
