System Introduction

Application areas:Suitable for detecting oxygen content in flue gas of industrial heating devices such as thermal heating, thermal power, petrochemicals, glass kilns, cement industry, energy and environmental protection. Especially suitable for monitoring oxygen content in environments with high dust content in flue gas (such as pre dust removal flue gas from coal-fired power plants, high dust flue gas from metallurgical sintering, etc.).

characteristic:

①A new type of sampling probe designed using the principles of thermal convection physics sprays and inhales sample gas, and the sample gas flows to automatically remove dust. Designed with ceramic filters and zirconia surface protective layers, the oxygen sensor is protected from direct contamination by high dust and corrosive gases, further improving the service life of the oxygen probe.

② Low voltage heating (DC15V), no high voltage, the heater is directly coated in the oxygen sensor in an integrated design, with high heating efficiency, stable temperature, and safe and reliable on-site use and maintenance.

③ The split structure allows the zirconia probe to be easily removed from the sampling probe for easy maintenance. It is designed with an online calibration hole that can be calibrated online or easily removed from the sampling probe for offline calibration.

① Oxygen probe measures ambient temperature: 0-1100 ℃;

② Transmitter output type: 4-20mA isolated transmission output;

③ Transmitter alarm output: One channel alarm output (optional);

④ Transmitter communication: RS485 isolated communication (optional);

⑤ System range: 0.01-20.9 O₂% ；

⑥ System response time: 5 seconds when the measured atmosphere changes at the probe measurement end;

When inputting standard gas into the probe calibration hole: reach 95% response value within 5 seconds;

⑦ System installation environment: Oxygen probe installation environment temperature:- 20~80℃；

Installation environment temperature for transmitter and oxygen probe maintenance instrument: -10~50 ℃; Humidity<90%;

⑧ Structure: The oxygen probe adopts a waterproof junction box, waterproof design, and can be installed outdoors; The transmitter and maintenance device are both wall mounted and designed to be waterproof, and can be installed outdoors;

⑨ Effective length of oxygen probe: 800mm, 1000mm, 1200mm Special customizable length;

⑩ Oxygen probe sampling tube material: SUS310 or corundum ceramic;

⑪ Explosion proof rating: ExdII BT4, ExdII CT6 (both customizable)

⑫Protection level: IP55、IP65

Customizable explosion-proof, high-temperature, and high dust zirconia oxygen analysis system!
