E ciudat, tehnologia cu fir e mai simpla si mai sigura in principiu. Are senzorul wireless vreo certificare de safety ? Cum este protejat impotriva interferentei cu vreo sursa de radiofrecventa apropiata ? Ca sa nu mai zicem de receptorul wireless, cel ce preia semnalul si genereaza comanda catre electroventil.
"Where can I use wireless devices?
The successful use of wireless devices
in a non-safety related monitoring application has led to the desire to expand into control and even safety applications. Wireless devices can be successfully used in application functions where they are not considered as 'Independent Protection Functions',
such as combustible or toxic gas detection, fire detection, leak detection and emergency shutdown switches."

Tipul care scrie asta e seful unui departament de safety de la ABB.
Deci nu e pentru detectie gaz combustibil.
