Probe for measuring dew point temperature in compressed air / HP480・HP481
Senseka (formerly Delta Ohm)
Measuring the dew point temperature of water vapor in the compressed air circulating in the system.
Compressed air is used in various fields and for different purposes, and in many cases, low humidity levels of compressed air are required. Therefore, it is necessary to know the dew point temperature (DP) of the water vapor in the compressed air circulating in the system. The HP480 probe is designed for this dew point temperature measurement. Dew point measurement for moisture control in compressed air distribution systems brings many advantages, such as: - Prevention of corrosion in metal pipes - Prevention of ice formation in pipes that can cause blockages in low-temperature areas - Prevention of bacterial growth in medical plants - Reduction of maintenance costs through proper lubrication of moving parts in pneumatic equipment - Improvement of product quality in air-contact products, such as in pellet drying processes ▲ High-precision dew point temperature (DP) measurement ▲ Compatible probe ▲ Quick coupling/thread connection ▲ Measurement chamber material AISI304
