EDS3-124C

IN-SITU ZIRCONIA OXYGEN ANALYZER ZSB DATA SHEET This oxygen analyzer is used to continuously measure oxygen concentration in combustion exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion moni-toring and control. The analyzer consists of a flow guide tube with a detector, which is directly inserted into a flue, etc. to introduce the gas to be analyzed, a transducer, which performs control, signal processing, display, input to and output from outside, and communication, and an auto calibration/blow unit. The detector of a unit sensor structure facilitates on-site maintenance. The transducer provided with an unconventional sensor diagnostic function and sensor renewal function ensures long-term stable detecting operation. FEATURES 1. No need for gas sampling devices Since the sensor unit is directly inserted into a flue, etc., gas-sampling devices such as gas aspirator and dehumidifier are not required, which ensures high response speed. 2. Easy maintenance The sensor in a unit structure mounted to the detector can be replaced easily. Since the detector and the flow guide tube are installed separately, the filter at the tip of the detector can be replaced easily, and detector and the flow guide tube can be maintained separately depending on the degree of formation of rust, for example. 3. High reliability ensured by the sensor diagnostic and sensor renewal functions Depending on the components in the gas to be measured, the sensor electrode may degrade. The transducer diagnoses the degree of degradation of the sensor and renews it electrically, thus ensuring high reliability and long-term stable measurement. 4. Improved safety Detecting a break of the thermocouple for heater control installed at the sensor, power supply to the detector is stopped. Furthermore, external contact input stops power supply to the detector in an emergency. Those functions along with the key lock function are equipped as standard to ensure improved safety. 5. Simple operation The transducer can be operated and various settings can be made using an interactive system, and display language is available in English, Japanese, and Chinese.

SCOPE OF DELIVERY 1) Standard delivery 1 set x zirconia oxygen analyzer 1 set x instruction manual 1 set x standard accessories · 1 x O -ring (for detector) · 1 x ceramic filter (for detector) · 2 each x fuse (3.15 A, 0. 5 A) · 1 set x inlet (for standard gas connection) · 1 x polyethylene tube (for standard gas connection) · 1 x Toaron tube (for standard gas connection) · 1 set x flow guide tube accessories (bolt, nut, spring washer x 4 pieces each) 2) Items to be prepared separately · Replacement detector · Spare (detector) Spares for 1-year operation 1 x O -ring 2 x ceramic filter 1 x Filter frame Spares for 2-year operation 2 x O -ring 4 x ceramic filter 2 x Filter frame CAUTIONS · If combustible gas (CO, H2 etc.) exists in the measured gas, error will occur due to burning at the sensor section. 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 (+300ºC or higher), the flange should be separated from the furnace wall in order to bring the detector flange surface temperature below the specified value (+125ºC). The flow guide tube should be attached in the direction in which the gas flow to the detector decreases. · If much dust is contained in the gas, the flow guide tube should be connected obliquely from the top. This tube should also be connected in the direction where gas flow into the detector section is reduced. · In application to refuse incineration, automatic blow-down of the flow guide tube should be avoided (in order to protect the tube from corrosion due to drain formation). Blow-down should be carried out manually when indication change becomes small during stop of the incinerator. 5 ZSB CONFIGURATION Rc1/4 (upper side blow port should be selected) Blow-down, 200 to 300kPa Solenoid valve (not supplied) Reduction valve (unnecessary when supply air pressure is 200 to 300kPa) Supply air Heat insulation cover Flow guide tube Detector (ZFK8) 15ASGP tube equivalent or φ10/φ8mm Teflon pipe or steel pipe (not supplied) 15ASGP tube equivalent or φ10/φ8mm Teflon pipe or steel pipe (not supplied) Gas temperature. 600ºC max. 6 Ref. air 5 1 2 3 4 White Black White Red Rainproof flexible conduit.
