Register to watch Customer case Malting process improved using Indigo500 with HMP7 and TMP1 probes As one of the world’s leading suppliers of high quality malt products, Viking Malt has investigated the advantages of continuous humidity monitoring inside the malting process at its facility using Vaisala’s Indigo520 and HMP7 and TMP1 probes. Learn more Customer case Optimized drying process helps Isolava cut energy consumption and improve end-product quality Isolava began a project to optimize the drying process, led by Project Engineer Peter Vaneyghen. The first step was to install humidity sensors in the dryer in order to get a better understanding of the dynamics of the drying process. The consumption of natural gas alone has decreased by some 20% and the annual savings across all ten dryers add up to hundreds of thousands of euros.

Unlike in the past when measurement probes could not be used on their own, the new wave of smart measurement probes can operate independently without additional transmitters. Learn more Blog Measuring humidity in condensing environments Taking measurements in environments with high relative humidity (over 90%) is always a challenge because the environment is so close to saturation.
