1.3 The System

1.3.1 System Components

A complete Optica system consists of the following items:
•
Electronic monitor
•
Dew point sensor
•
Interconnecting sensor cable
•
AC line cord
•
Certification that the unit is traceable to the National Institute of Standards
and Technology (Certificate of Conformance)

1.3.2 System Planning

The Optica can be used for a wide variety of measurement applications, including the measurement of dew points of
gasses that are at pressures that exceed the measurement range of GE sensors. In this situation be sure to check
"Process Pressure" on page 30 for installation planning.

1.4 Sensors

The Optica can be configured with a chilled-mirror dew point sensor. The specific sensor is chosen according to the
expected dew point range and the environment in which the dew point is to be determined. In addition, the Optica can
be configured with a temperature and/or pressure sensor.

1.4.1 Dew Point Sensors

GE offers the following sensors for various applications:
•
Model 1111H - Single-stage sensor
•
Model 1211H - Two-stage sensor; high pressure and temperature
•
