Use this complete model number for any correspondence with Emerson. A list of accessories for use with the Hazardous Area OCX 8800 is provided in Table 1-2.
Page 26: System Overview
Hazardous Area OCX 8800. Signal conditioning electronics outputs a digital signal representing oxygen (O ) and combustibles (COe) values. This information, plus additional details, can be accessed with the 375 Field communicator or Emerson AMS software. The optional local operator interface (LOI) also provides a communications interface with the electronics.
Page 27: System Description
Instruction Manual Section 1: Description and Specifications IM-106-880C, OI April 2017 1.3.2 System Description The Hazardous Area OCX 8800 is designed to measure oxygen and combustible concentrations in flue gas temperatures up to 2600°F (1427°C). Electrical connections, power and communications are made through two 3/4 NPT ports in the flameproof electronics enclosure using fittings and cables provided by the customer.
Page 28: System Configuration
Section 1: Description and Instruction Manual Specifications IM-106-880C, OI April 2017 The Hazardous Area OCX 8800 combustibles sensor is a catalytic sensor consisting of two Resistance Devices (RTD). One RTD is the reference element covered with an inert coating. The other RTD element is active, coated with a catalyst. As the sample gases flow by the sensor, the combustible gases oxidize on the surface of the active element.
Page 29: System Features
Device Description (DD) software specific to the Hazardous Area OCX 8800. The DD software will be supplied with many Model 375 units, but can also be programmed into existing units at most Emerson service offices. Refer to Section 6, Field Communicator, for additional information.
Page 30: System Operation
Section 1: Description and Instruction Manual Specifications IM-106-880C, OI April 2017 1.3.5 System Operation Figure 1-2 shows the relationship between the components of the Hazardous Area OCX 8800. The sensors and the electronics are contained in separate housings. The sensor housing and probe mounts to a duct or process wall so that the probe protrudes into the flue gas stream.
