 Our Impedance hygrometers are rugged, low-cost,
industrial measurement instruments for reliable moisture analysis from trace
levels to ambient air conditions. They can be used in a wide range of gases,
including hazardous area applications (flammable or explosive gases) and with
many corrosive gases. All Impedance instruments use Michell's Advanced Ceramic
Moisture Sensor technology.
The Ceramic Sensor is constructed using
state of the art thin and thick film techniques. Operation of the sensor
depends upon the adsorption of water vapor onto a porous non-conducting
"sandwich" between two conductive layers built on top of a base ceramic
substrate. The active sensor layer is very thin - less than one micron (about
0.00004 inches) and the porous top conductor that allows transmission of water
vapor into the sensor is even thinner. Therefore the sensor responds very
rapidly to changes in applied moisture, both when being dried (on process
start-up) and when called into action if there is moisture ingress into a
process.
Despite this extreme sensitivity to changes in moisture
content, the Michell Ceramic Moisture Sensor is incredibly rugged due to the
nature of its construction. To protect the sensor further against contaminants
and pipe swarf it is housed in a protective sintered stainless steel guard. All
Michell Ceramic Moisture Sensors give <1°F dew point accuracy and
excellent long-term reliability and stability in process applications.
