Process efficiency

Humidity is one of the most important parameters which can be used in maximizing the efficiency of powder dryer operations. Measurement
of Absolute Humidity in an accurate and reliable way has always been a challenge for powder producers. Traditional dew point measurement technology has proven to be inaccurate and unreliable for most applications. Hobré’s innovative sample conditioning system allows you to produce a dry and stable product.

Principle of operation

The system will sequentially measure both sample streams in only 60 seconds per sample. The operator can receive continuous information and updates of the H2O levels of the two sample streams. The H2O level is given in vol.% or g/kg dry air. The system is designed for low maintenance and reliable operation. The low-pressure sample system requires no heating as there is no condensation of water. Sample streams are continuously flushed for short lag time and fast response. The tunable diode laser (TDL) analyzer generates accurate measurements of the absolute humidity.
