Pressure sensor

I have an s7-1500 with a DI and a DQ module

I have air at 6 Bar and I need to know if there is a pressure drop. I don't really care what the pressure reading is, I just need to know when it drops.

I need the cheapest, most simple way to do this.

Thanks everyone!

Festo sells pressure switches that can be adjusted with a screw for the ON/OFF pressure point. This or similar is the best to use for industrial purposes.

Sorry.. I have no part number to give you - - but Festo's online catelog is one of the best.... so give it a try to see what they have before looking for cheaper.

PS.... think S7-1200 next time you want cheaper. (wink)

Good luck.

Hello,

the suggestion of William_B  with FESTO is a good suggestion.

Please look at this links:
