Explosion proof zirconia oxygen analyzer

main features

*Used for monitoring the oxygen content of combustion gases in various boilers, industrial furnaces, and combustion devices, or for controlling low oxygen combustion.

*There are two types of instruments: separated and integrated

*Direct insertion analytical instrument, no sampling required

*The separated controller adopts an LCD touch display screen, which is easy to operate

*The probe and controller of the integrated analyzer are integrated, reducing wiring, piping, and installation costs

*The built-in heater of the probe can be replaced on site, reducing maintenance costs

*The probe adopts three reference gas compensation methods (air, standard gas, and pressure compensation gas)

Technical Parameter

Measurement range: 0.01~100vol% O2 0~100vol% H2O or 0~1.000kg/kg

Sample gas temperature: 0-700 ℃ (only referring to the probe part). When the temperature exceeds 600 ℃, a conductivity cell with Inconel conductivity cell screws needs to be installed. 700-1400 ℃ (with high temperature probe adapter). For high-temperature gas samples, a 0.15m long probe and high-temperature probe adapter ZO21P-H should be used

Sample gas pressure: -5 to+250kPa (pressure compensation is recommended when the pressure inside the furnace exceeds 3kPa). When the pressure inside the furnace exceeds 5kPa, pressure compensation must be carried out. For a 0.15m probe, the range is 0.5-5kPa, and there is no pressure fluctuation inside the furnace

Output signal: 4-20mADC, (maximum load resistance 550 Ω)

Digital communication (HART): 250-550 Ω, depending on the number of field devices connected in the loop (multi-point mode)

Materials in contact with gases: SUS316 (JIS), zirconia, SUS304 (JIS) (flange), HasloyB（Inconel600,601）

Structure: The heater and thermocouple are replaceable structures. Non explosion proof products. Equivalent to NEMA4X/IP66 (only applicable for pressure compensated furnace recirculation)

Installation methods: pipe installation, plate installation, wall installation

Power supply voltage: rated 100-240VAC, acceptable range: 85-264VAC

Power frequency: rated: 50/60Hz, acceptable range: 45-66Hz

Environmental temperature: Separated transmitter and integrated -20~55 ℃, separated probe -20~150 ℃
