Produktbeschreibung

general information:

Compressed air is used for several purposes, many of which require compressed air with a low humidity level. So it is necessary 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

specifications:

relative humidity:	sensor: capacitive measuring range: 0 % to 100 % r.h. accuracy (at T = +15 to +35°C): ±1.5 % r.h. (0 to 90 % r.h.), ±2 % r.h. (remaining range) accuracy (at T = -40 to +60°C): ±(1.5 + 1.5 % of measured value) % r.h. long term stability: <1 % r.h./year
temperature:	sensor: Pt100 measuring range: -40°C to +60°C accuracy: ±0.25°C
dew point:	sensor: parameter calculated from the measurement of temperature and relative humidity measuring range: -40°C to +60°C DP accuracy (at T = +20°C): ±2°C DP (-40°C to 0°C DP) ±1°C DP (0°C to +20°C DP) accuracy (at T = -40 to +60°C): see graph 1 (data sheet)
