Delta Ohm HP481 Interchangeable Temperature, Relative Humidity (RH) Probe, -40…+60 °C, 0…100%RH

Compressed air is used for several purposes, many of which require compressed air with a low humidity level, and so comes the need to know the dew point (DP) of water vapour in the compressed air that circulates in the system.

The HP480 and HP481 probes are designed specifically for this purpose.

The use of dew point measurement in order to limit moisture in compressed air distribution systems has many advantages:

• Prevents corrosion of metal pipes;
• In cold areas, prevents the formation of ice inside the pipes leading to obstruction of the pipes themselves;
• Prevents bacterial growth in plants for medical use
• Reduces maintenance costs of pneumatic drives, maintaining the proper lubrication of moving parts;
• Improves the quality of products coming into contact with air, for example in the drying process of granulates.
