Zirconia oxygen analyzer

Zirconia oxygen analyzer--Jinhu Tianxiang Instrument Co., Ltd. Quality is the life of the enterprise, and every product is a masterpiece of craftsmanship!

ZR22S/ZR202SExplosion proof zirconia oxygen analyzer:

There are two types of on-site direct insertion explosion-proof zirconia oxygen analyzers to choose from.ZR22S/ZR402GIt is a split type, composed ofZR22SExplosion proof probe and

ZR402GComposed of non explosion proof converters.

ZR202SIt is an integrated analyzer that combines a probe and a converter. Both zirconia oxygen analyzers do not require sampling equipment and can directly install the probe in the flue wall or furnace body to measure the oxygen concentration in the flue gas. The converter displays the zirconium pool temperature, zirconium pool electromotive force, and oxygen concentration.

This analyzer is highly suitable for monitoring combustion and controlling low oxygen combustion in various industrial furnaces in explosive environments, such as refineries, petrochemical plants, and natural gas plants.

Characteristics:

• The embedded probe heating device can be replaced on site, reducing maintenance costs.
• The probe adopts zirconia sensors with long service life and high reliability.
• Split type converterZR402GEquipped with an LCD touch screen, easy to operate.
• Integrated typeZR202SIntegrating probes and converters to reduce wiring, piping, and installation costs.ZR202SThe unit adopts optical switches, which are easy to operate on site.
• Use digital communication (HART) for remote maintenance to reduce maintenance costs.

3. Attention to selection of zirconia probes

For the frequent use of our company's intelligent instruments in industry, we must have a good understanding of the usage environment. The temperature range of the flue gas is 800 degrees, which belongs to a low-temperature environment. We use standard zirconia probes. For environments above 800 degrees, we use low temperature zirconia probes. If the flue gas contains a high concentration of sulfur dioxide and SO2 gas, we use specially designed probes.

The detector consists of main components such as dust prevention device, zirconia tube, heating furnace, thermocouple, gas conduit, junction box, and housing. The entire device adopts a fully enclosed structure to increase its sealing performance and improve its service life. For high dust detection environments, porous ceramic filters were installed to achieve better filtration efficiency.

The zirconia tube inside the detector is the core component and is a fragile ceramic item. During transportation, installation, and use, severe vibration should be avoided to prevent damage. The function of the heating furnace inside the detector is to provide the temperature required for the normal operation of the zirconia element. In order to extend the service life of the heating furnace, special treatment has been made in the process. Due to the heating device of the detector itself, it can work normally in environments below 700 ℃.
