What sensor would you use to monitor compressed air (plant air 100-120psi) moisture levels?

This would be an input to a control logix plc: analog, I/O link, Ethernet I/P etc. for monitoring by our SCADA.

Vaisala probably has one that would work. The ones that we used on our Zurn are so old that they aren't being manufactured any longer.

You need a dew point sensor.

Just bought an IFM Efector LDH100 with an E43400 mounting block.

Haven't tried it yet.
