GE's Optica Series chilled mirror hygrometers offer National Institute of Standards
and Technologies (NIST)-traceable humidity, temperature and pressure measurements
for the connected generation. Now data is accessible from anywhere, any time,
from within a browser over the Internet or from your Intranet.
Fundamental dew point measurement is a primary measurement used as a transfer
standard for calibrating other humidity instruments and sensors. Chilled mirrors
are also the sensors of choice when process and laboratory measurements call
for high precision without long term drift. Optica may be used with five, fully
interchangeable chilled mirror sensors to provide a measurement range from -112°F
to 185°F (-80°C to 85°C) dew point with 0.36°F (0.2°C) or
better accuracy.
The Optica simultaneously measures dew point, temperature and pressure. The
analyzer is equipped with programmable math functions to produce custom units.
The analyzer input channel is a standard 4 to 20 mA/0 to 5 VDC input, so the
Optica can be connected to any type of process transmitter and be confi gured
to display engineering units.
