What is dew point and why it is important in instrument air?
The Dew Point is the temperature at which water vapor starts to condense out of the air (the temperature at which air becomes completely saturated). Above this temperature the moisture will stay in the air.
Electronic instruments uses instrument air received from instrument compressors must be free of any moisture. Because even a very small amount of moisture may condense and give enormous deviation between actual value and displayed value which would result in many problems. So the instrument air should be free of moisture. This is ensured by keeping the dew point below ‑400C or below.
