The equipment that you bought has required the extraction and use of natural resources for its production. It may contain hazardous substances that could impact health and the environment.

  • Page 13: Chapter 1. Features And Capabilities

    Using the Optica, you can simultaneously measure and display dew point, temperature and pressure, with a wide variety of units of measure. The Optica is Ethernet-ready, so you can access the unit using the Internet for remote monitoring applications. You can use the data logging function to record and upload weeks of data.

  • Page 14: Front Panel

    Chapter 1. Features and Capabilities 1.2.1 Front Panel The Optica front panel is shown in Figure 1 below. The panel includes: a display, an alphanumeric keypad for data entry, ENTER and TAB keys, and four softkeys to the right of the display screen.

  • Page 15: The System

    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.

  • Page 16: Theory Of Operation

    1.5.1 Hygrometer Function Figure 2 below illustrates how GE Measurement & Control hygrometers detect and measure dew point. The condensate mirror is illuminated with a solid state, infrared emitter (IR). A photodetector monitors the IR light reflected from the mirror. The photodetector is fully illuminated when the mirror is clear of dew, and it receives less light as dew forms.

  • Page 17: Hygrometer Calibration

    The GE optical condensation sensors cover a wide range of applications limited only by the heat pumping capabilities of the thermoelectrically-cooled mirror.

  • Page 18: The Pacer Cycle

    (Programmable PACER Automatic Contaminant Error Reduction) that is very effective in reducing the Raoult Effect error associated with soluble contaminants, particularly for near-ambient dew points. The Optica is equipped with the cycle as well as PACER balance as found on earlier models. The user can choose which self-cleaning and balancing routine to run AUTO depending on the severity of the contamination.

    2.2 Benchtop Optica Installation 2.2.1 Mounting the Benchtop Optica The Optica benchtop dimensions are shown in Figure 5 below. Two feet on the bottom of the case can be unfolded to raise up the front for easier viewing, if desired.

  • Page 20: Using The Rack Mounting Option

    There is an optional kit for mounting the benchtop unit in a standard 19-inch rack (see Figure 6 below, Figure 7 on page 9, and Figure 8 on page 10). The two brackets are attached to the front panel using four #8 screws. The Optica is mounted to the brackets using the eight mounting holes located just in front of and behind the unit’s feet.

    2.6.7 Connecting the Sensors Dew point, temperature and pressure sensors provided by GE for the Optica monitor are pre-wired with connectors installed. Plug these connectors into their corresponding sockets as shown in Figure 9 on page 11 for the benchtop unit, or Figure 12 on page 13 for the wall-mount unit.

  • Page 39: Chapter 3. Operation

    3.2 Normal Operation Normal operation of the Optica is very simple. To turn the unit on, check that the main power switch on the rear of the benchtop unit is set to ON (—), then press the right-hand side of the power switch (located at the lower left corner on the front of the unit).

  • Page 40: Operating The Vga Optica

    The parameters chosen during programming are displayed numerically in the top half of the screen, and graphically at the bottom (see Figure 23 below). To program the unit, see Chapter 4. “Programming the VGA Optica“. A balance indicator is shown as a vertical bar on the right side of the screen. It shows the state of the feedback control loop controlling the mirror temperature.

  • Page 41: Network Operation

    Chapter 3. Operation 3.5 Network Operation The VGA Optica can be operated and programmed remotely over a network. Networked operation is very similar to operation using the front panel. For programming from a network, see Chapter 6. “Network-Based Programming“. A typical network screen is shown in Figure 25 below.

  • Page 42: Process Pressure

    500 psi. A sampling system can be arranged to allow the measurement to be made at atmospheric pressure. The Optica can then calculate and display the dew point at the process pressure (see “Scenario 2: Measurement Requiring the Process Pressure Feature” on page 32).

  • Page 43: Scenario 1: Measurement Without Enabling The Process Pressure Feature

    3.6.4 Scenario 1: Measurement Without Enabling the Process Pressure Feature Process pressure is 100 psi, within the range of a typical GE chilled mirror sensor. Since vapor pressure and dew point are pressure-dependent, a flow meter is installed downstream of the sensor to assure that the sensor cavity is at the process pressure (see Figure 26 below).

  • Page 44: Scenario 2: Measurement Requiring The Process Pressure Feature

    3.6.6 Scenario 2: Measurement Requiring the Process Pressure Feature Process pressure is 500 psi, above the measurement range of a typical GE chilled mirror sensor. A flowmeter is installed upstream of the sensor cavity to expand the gas to be within the measurable range of the dew point sensor.

    The sensor location and hookup arrangement can influence the pressure. When the pressure at the sensor is different from the process pressure, the Optica can perform a conversion from the measured pressure to the desired process pressure (see “Process Pressure” on page 30 for details).
