Series 300 Flue Gas Analyzer

Accurate Monitoring of Combustion Processes The Series 300 microprocessor-based flue gas analyzer provides continuous and accurate monitoring of all types of combustion processes, from simple boilers to specialized heat-treatment furnaces. It uses a proven zirconium-oxide oxygen sensor and a catalytic combustibles sensor. The unique design allows a single system to cover a process temperature range from 392 to 3,092 °F (200 to 1,700 °C).

Product Description:

The microprocessor-based electronics of the Series 300 can display the usual percent excess oxygen and trace combustibles in flue gas. In addition, special parameters such as air factor, combustivity index, excess fuel and equivalent combustibles can also be displayed with the touch of a button on the membrane keypad. At the flip of a switch, the Series 300 electronics makes a specific fuel—such as natural gas, oil or coal—the default fuel. Thereafter, all calculations are based on the selected fuel.

The Series 300 analyzer is available in horizontal or vertical mounting configurations in either weatherproof or explosionproof packages. The Series 300 digital display is available in rack, bench, panel, weatherproof and explosionproof packages. Built-in diagnostic features, such as sensor open circuit, analyzer plugging and sensor aging, are included as part of the software package. Linear output in the form of voltage or current and one alarm relay are available for both the oxygen and combustibles sensors.

Features & Benefits:

• Measures excess oxygen and combustibles in flue gas
• Ultrastable furnace provides best accuracy
• Temperatures from 392 to 3,092 °F (200 to 1,700 °C)
• Proprietary coatings extend oxygen sensor life
• Plug-resistant, filter-free probe
• Heater block prevents condensation and corrosion

TMO2-TC Gas Analyzer

Wide Variety of Applications The TMO2-TC gas analyzer provides sensitive, accurate, online analysis of composition based on the thermal conductivity of gases in a mixture. It uses two ultrastable precision thermistors: one in contact with the sample gas and one in contact with a sealed or flowing reference gas. Since it has no moving parts, the transmitter can handle shock and vibration. Its unique design makes it insensitive to contamination and sample flow rate variation.

Product Description:

The TMO2-TC can be field calibrated or, due to its modular construction, the plug-in measuring cell can be quickly replaced with a precalibrated spare.

Gas : XMO2 Thermoparamagnetic Oxygen Transmitter

Accurate & Reliable Long-Term Measurement The XMO2 transmitter provides computer-enhanced, drift-free oxygen measurement in a compact, rugged, online transmitter. It can be used wherever accurate and reliable long-term oxygen measurement is critical to process and product quality. This includes inerting/blanketing liquid storage tanks, reactor feed gases, flare gas, catalyst regeneration, oxygen purity and many other applications.

Product Description:

The XMO2 is specifically designed to overcome the limitations of conventional oxygen analyzers. It does not require analyzer shack installation in a general-purpose area, but can be field-mounted at the process measuring point. This minimizes sample conditioning requirements and ensures the best sample and the fastest possible response. Unlike other paramagnetic oxygen sensors, the XMO2 has no moving parts, making it insensitive to mounting position or vibration and providing excellent long-term reliability. The unique, dual-chamber oxygen cell design insures insensitivity to contamination and flow variations and provides a zero and span stability that makes recalibration typically only a biannual requirement.

An on-board microprocessor enables the XMO2 to provide advanced online signal detection and conditioning, real-time error detection and automatic compensation of the oxygen reading for background gas and/or pressure variations. This results in a linearity of better than 0.5 percent of span, a long-term accuracy of 1 percent of span and a stability of 0.8 percent of span per month. A proprietary fast-response software routine enhances the standard response of the thermoparamagnetic oxygen sensor, providing typical times of less than five seconds for a 63 percent response.

The user-friendly XMO2 can be programmed in the field or remotely with application-specific data via an RS232 interface and three-level, menu-driven software. When recalibration becomes necessary, it can be accomplished quickly and easily through software, with no pots to adjust. A complete line of performance-enhancing accessories make the XMO2 even easier to use. These accessories include custom-designed sampling systems and different styles of digital display packages.

The XMO2 transmitter requires 24-VDC power and provides an isolated 4- to 20-mA output signal for oxygen concentration that is programmable for zero and span. It is available in either weatherproof (NEMA 4X, IP65) or explosion-proof (NEMA 7) enclosures and in ranges from 0 to 1 percent to 0 to 100 percent, making it suitable for a wide variety of installations and applications.

Features & Benefits:

Measures oxygen from 0.01 to 100 percent in gases

No moving parts; maintenance-free

Corrosion-resistant design

Automatic background-gas compensation

Use as stand-alone transmitter or in conjuction with TMO2D or XDP display packages
