PRODUCT DESCRIPTION
Emerson Process Management, the world leader in process gas analyzers, offers the CAT 200 multi-component, multi-technology Continuous Gas Analyzer Transmitter with flameproof (explosion proof) packaging. The CAT 200 provides superior performance and has been designed for precise, continuous gas measurements in a variety of applications.
FIELD MOUNTABLE HOUSING
The CAT 200 is housed in a Class I, Zone 1 (IIB) + H2 approved transmitter-style enclosure that can be field-mounted in the harshest environmental conditions. The enclosure can be mounted near the process without requiring ambient controls or costly and space-consuming shelters. This feature greatly reduces installation and utility costs while vastly improving process efficiency.
MULTI-MEASUREMENT CAPABILITY
The CAT 200 can continuously measure up to 4 components in a single analyzer using a combination of non-dispersive infrared, ultraviolet and visible (NDIR/UV/VIS) spectroscopy, paramagnetic or electrochemical oxygen, and thermal conductivity sensors. This exceptional flexibility has been achieved by combining the most sophisticated gas detection sensor technology with close-coupled Digital Signal Processing (DSP).
ANALYZER NETWORKS
The CAT 200 can network with up to 15 other CAT 200 or MLT, FID or CLD analyzer module channels. The analyzer module is a blind analyzer unit, but retains all of the advanced CAT 200 design features. In addition to the operational benefits, the CAT 200 offers significant installation and maintenance savings not possible with conventional analyzers. The CAT 200 analyzer’s unique network capability allows the user to easily route all of the field-mounted analyzer module inputs, outputs and diagnostics into one easily accessed central location.
MEASUREMENTS
The CAT 200 brings together more than 40 years of development and process application expertise including the latest sensors, digital signal processing and software technologies. The CAT 200 can satisfy the most demanding single or multi-component analysis requirements. More than 60 gas components can be measured including: Carbon Monoxide (CO), Oxygen (O2), Carbon Dioxide (CO2), Water (H2O), Sulfur Dioxide (SO2), Methane (CH4), Nitrogen Dioxide (NO2), Hydrogen (H2), Ammonia (NH3), Ethylene (C2H4), Phosgene (COCI2), Acetone (C3H6O), Chlorine (CI2), Methyl Alcohol (CH3OH), Toluene (C7H8), Vinyl Chloride (C2H3CI), Hydrogen Cyanide (HCN), Acetic Acid (CH3COOH), Styrene (C6H5CHCH2), Ethylene Oxide (C2H4O) Acrylonitrile (C3H3N), Acetylene (C2H2), Carbon Disulfide (CS2) and R 134A (C2H2F4).
TOUCHPAD CONTROL
The CAT analyzer's magnetically-operated user interface is placed behind an impact-tested safety glass. It offers the user setup and control capabilities without needing to open the analyzer housing or shut off power. All analyzer key functions are accessible including autocalibration, limit alarms, range selection, diagnostics and much more by simply pointing a magnetic tool at the appropriate function key.
ADVANCED I/O FUNCTIONALITY WITH PLC/CALCULATOR OPTION
Using optional SIO and DIO boards, the flexibility and diversity of the CAT can be expanded well above other analyzers. These boards allow the user to selectively choose from more than 80 different signals and parameters including:
Up to 8 programmable analog output channels: concentration, temperature, pressure, flow, calculator results
Up to 3 relay contacts, programmable, e.g. acc. to NAMUR: unit failure, check request, function check
Serial interfaces: RS 232 or RS 485
Up to 15 digital outputs and 6 digital inputs: zero and span initiate and in progress, concentration alarm, flow alarm, range identification, etc.
SAMPLE HANDLING/CONDITIONING OPTION
With the addition of a sample handling and conditioning system mounted to an integral plate, the CAT 200 becomes a complete stand-alone in-field, transmitter-style analyzer system. The sample conditioning plate option is a small and efficiently-designed system that is bolted directly onto the analyzer housing at the factory for a final one-piece system construction. This one-piece unit can then be easily mounted to a process pipe. This feature offers highly efficient process monitoring and fast installation at low cost. The sample conditioning system is designed by experienced Emerson Process Management engineers who will tailor the sample handling system around your particular process parameters and required measurements.
Alternately, the CAT 200 design can incorporate internal sample handling options such as a gas sampling pump, flowmeter, flow restrictor and solenoid valve block for autocalibration and remote valve and calibration control. Two pumps, flowmeters and valve blocks are available as a special solution for parallel tubed benches.
FOUNDATIONTM FIELDBUS COMMUNICATIONS OPTIONS
FOUNDATION fieldbus offers the newest, most innovative field control architecture available. A two-wire digital communications protocol enables individual instruments to communicate together and be interoperable with other FOUNDATION fieldbus capable instruments. This communications protocol can carry vast amounts of information that is not accessible by using standard analog or digital data acquisition methods -- information not only about the process, but also about the equipment controlling it.
