The Jumo Wtrans temperature measuring system line has been extended by a transmitter with Atex approval and transmitters containing a highly temperature-resistant electronics module, that can be used up to a temperature of 125 °C. Transmitters with Atex approval can be put directly into a potentially explosive atmosphere. The receiver is mounted outside the actual EX zone. This means that cost-intensive installations with protective barriers and supply isolators are unnecessary. The Wtrans transmitter can be located in Zone 0, right up to the process connection. In this example, the probe handle is in Zone 1. Of course, it is also possible to operate the entire instrument in Zone 1. The transmitter is still located in the probe handle and is protected by a waterproof and dustproof housing. A blue plastic handle was chosen as an outward distinguishing feature. Instruments with a temperature resistance up to 125 °C are used in applications where it is mandatory for the transmission electronics to be installed in the actual process. A gray plastic handle is the outward distinguishing feature here.
There are versions that can be used to measure from -30 to +260 °C with a fixed protection tube, as well as versions for a temperature range of -200 to +600 °C with M12 connectors and a remote temperature sensor. Hall 9, Booth D06
