Fan monitoring in EX zone

I received a requirement from TÜV that I have to monitor an ATEX fan externally, regardless of the speed. As I also have to comply with SIL2, this device fits the bill perfectly. Mr. Weißer gave me perfect advice and the device was here within a week. I am completely satisfied!
