1 IN-SITU IRCONIA OXYGEN ANALYER DATA SHEET FK8, KM, TA This oxygen analyzer is used to continuously measure oxygen concentration in combustible exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion management and control. Setting configurations are flow guide tubes which conduct measured gas to the detector inserted directly, detectors which are fitted with flow guide tubes (FK8), control detectors, signal processing, displays, external input/ and communication converters (KM), detectors and converters are coupled together. The Detector is composed of unit sensor, easy to maintenance on spot. The converter is equipped with non-conventional function such as performing the sensor diagnostics and sensor recoverable function, so the detector can be used within long term stability. General-use detector (FK8) High-temperature detector (TA) FEATURES. Gas sampling device is unnecessary For quick response, insert the detector to a flue directly. Gas sampling functions such as a gas aspirator and a dehumidifier are not required.. Easy maintenance The sensor equipped with the detector, has unit construction, it is easy to replace. By separating the detector and the flow guide tube, filter replacement can be easy, and possible to maintain them individually.. More reliable than sensor diagnosis, sensor recoverable function Depending on the component of the measurement gas, the power of the sensor might be deteriorated. The equipment includes sensor recoverable function by electronic, checking the deterioration of the converter as standard equipment. Because of that, it has high reliability and you can measure within long-lasting stability. 4. Safe and secure The equipment detects the break of thermocouples for heater control which equipped on sensor side, also includes the function which stops a power supply to the detector, or also stops a power supply by external contact input to the detector in an emergency and key lock functions as standard equipment. So you can use it at ease.. Easy operation The operation and setting for the converter can be performed interactively, and are available to select from English, Japanese and Chinese for language display. <IP66> SPECIFICATIONS Converter (KM) <IP> General Specifications Measuring object: Oxygen in noncombustible gas Measuring method: Directly insert type zirconia system Measuring range: 0 to setting range at option in 0 vol% O (in vol% O steps) Repeatability: Within ±0.%FS Linearity: Within ±%FS Response time: Reply 90% less than 6 sec.

The inclusion of corrosive gas (Si vapor, alkaline metal, P, Pb etc.) will shorten the life of the sensor. When the measured gas temperature is high (+00 C or higher), the flange should be separated from the furnace wall in order to bring the detector flange surface temperature below the specified value + C). The flow guide should be attached in the direction in which the gas flow to the detector decreases. When much dust is included in the gas, the flow guide tube should be attached at an inclination so that the flow goes from below to above. And the flow guide should be attached in the direction in which the gas flow to the detector decreases. In the case of a refuse incinerator, automatic blow down of the flow guide should not be performed (to prevent corrosion of the flow guide tube due to drainage). Blowdown should be performed manually when change in the indication has become very little with the furnace stopped. 4
