Application note

Dew point sensing technologies and their performance differences in compressed air applications

Moisture is a constant issue in compressed air systems. When dew point sensors are working optimally, measures can be taken to avoid malfunctions, inefficient operations or poor quality end product. However, the measurement of dew point in compressed air systems can present many challenges that lead to erroneous readings, poor stability, and even sensor failures.
