Dew-Point Transmitters The hygrometer of choice for the measurement of dew point, temperature, or gaseous moisture applications with a choice of units of measurement or where pressure compensation is required. Wide measurement range, calibrated -100 to +20°C (-148 to +68°F) dew point Industrial gases ±1°C (±1.8°F) dew point measurement accuracy Welding gases Pressure sensor input Glove boxes Medical gases User selectable units of measurement High voltage switchgear (SF6) Easy to read display
Abrir o catálogo na página 1Dew-Point Transmitters Cermet II Hygrometer Complete On-Line Dew Point Solution Cermet II is the intelligent choice for reliable on-line measurement of moisture in virtually any gas, across many applications. Cermet II combines Michell’s Advanced Ceramic Moisture Sensor and a monitor unit that can be located up to 1200 m apart (3930 ft). While Cermet II is so simple to use, it has the flexibility to be applied to almost any humidity measurement application. The instrument can display measurement units in °C or °F dew point, ppmV, lb/mmscf or g/m3 across the measurement range -100 to +20°C...
Abrir o catálogo na página 2Dew-Point Transmitters Technology: Impedance The Cermet uses Impedance technology, based on Michell’s advanced ceramic sensor. The operation of this sensor depends on the dielectric property of water molecules absorbing onto an active porous insulating layer sandwiched between two layers of conductive material deposited on a ceramic substrate. Water has a very high dielectric compared to the dielectric of the active layer and the background of the carrier gas so it can be detected easily. The active layer is very thin – less than one micron and the porous top conductor that allows water...
