Wet Sensor & DrySense Comparison

DrySense Creates Sensor Stability

Our patented no-drift DrySense velocity sensor technology uses a  proprietary swaging process which eliminates all air gaps between the heated velocity sensor and the tubular probe sheath eliminating the need for any potting compounds. The result is maximum sensitivity, reproducibility, immunity to cracking and shifting over time, and ultimately greatly improved accuracy, all backed by a lifetime warranty.

Wet Sensors Decrease Accuracy

The heated velocity sensor in other manufacturers’ thermal meters is inserted into the tip of a tubular probe sheath and surrounded by organic potting compounds such as epoxy, ceramic cement, thermal grease, or alumina powder.  These so-called “Wet” sensors have  long-term measurement errors caused by aging and cracking due to differential thermal expansion between the parts of the heated velocity sensor.
