 Precautions in Handling Explosion-proof Zirconia Oxygen Analyzer

The explosion-proof zirconia oxygen analyzer (Model ZR202S) are designed as explosion-proof instruments.

When using either of these instruments in an explosion-susceptible hazardous area, note the following and observe the given precautions:

Use only the supplied, the explosion-proof zirconia oxygen analyzer (Model ZR202S) and

accessories, or any explosion-proof certication may be invalidated.

For the details, refer to the system congurations in the manual.

CAUTION

Only trained persons use this instrument in industrial locations.

 For the safe use of this equipment

WARNING

EXAxt ZR is very heavy. Be sure not to accidentally drop it. Handle safely to avoid injury.

Connect the power supply cord only after conrming that the supply voltage matches the rating of this equipment. In addition, conrm that the power is switched off when connecting power supply.

Some process gas is dangerous to people. When removing this equipment from the process line for maintenance or other reasons, protect yourself from potential poisoning by using a protective mask or ventilating the area well

CAUTION

Requirements for explosion-proof use:

The ambient temperature is in the range of -20 to +55ºC. The surface temperature of the ZR202S is not over the temperature class T2 (300ºC)*

* The surface temperature of the amplier box does not exceed 70ºC.

Oxygen concentration of sample/reference /calibration gas shall not exceed that found in normal air, typically 21 vol%.

IM 11M13A01-04E

NOTE

The cell (sensor) at the tip of the probe is made of ceramic (zirconia element). Do not drop the equipment or subject it to pressure stress.

• Do NOT allow the sensor (probe tip) to make contact with anything when installing the analyzer.

• Avoid any water dropping directly on the probe (sensor) of the analyzer when installing it.

• Check the calibration gas piping before introducing the calibration gas to ensure that there is no leakage of the gas. If there is any leakage of the gas, the moisture drawn from the sample gas may damage the sensor.

• The probe (especially at the tip) becomes very hot. Be sure to handle it with gloves.

ZR202S Integrated type Explosion-proof

Hazardous Area

unit case

1. Overview

The EXAxt ZR Integrated type Explosion-proof Zirconia Oxygen Analyzer is used to monitor and control the oxygen concentration in combustion gases, in boilers and industrial furnaces, for wide application in industries which consume considerable energy-such as steel, electric power, oil and petrochemical, ceramics, pulp and paper, food, or textiles, as well as incinerators and medium/small boilers. It can help conserve energy in these industries. The EXAxt ZR also contributes to preservation of the earth’s environment in preventing global warming and air pollution by controlling complete combustion to reduce CO2, SOx and NOx.

The EXAxt ZR Integrated type Explosion-proof Zirconia Oxygen Analyzer integrates both probe and converter. The analyzers need not use a sampling device, and allow direct installation of the probe in the wall of a flue or furnace to measure the concentration of oxygen in the stack gas of the temperature up to 700°C.

The probe uses a high-reliability Zirconia sensor and a heater assembly that can be replaced on site.

The analyzer is equipped with three infrared switches, which enable the user to operate the equipment without opening the cover on site. Analyzer calibration can also be fully automated and the automatic calibration unit is provided. Choose the equipment which best suits your needs so that an optimal combustion control system can be obtained.

Some examples of typical system conguration are illustrated below:

1.1 < EXAxt ZR > System Conguration

The system configuration should be determined by the conditions; e.g. whether the calibration is to be automated, and whether flammable gas is present and requires safety precautions. The system

conguration can be classied into two basic patterns as follows:

1.1.1 System 1

This system is for monitoring and controlling oxygen concentration in the combustion gases of a large-size boiler or heating furnace. Instrument air (clean and dry air of oxygen concentration 21%) is used as the reference gas and the span gas for calibration. Zero gas is fed from a cylinder during

calibration. The gas ow is controlled by the ZA8F ow setting unit (for manual valve operation).

1.1.2 System 2

This example, System 2, represents typical applications in large boilers and heating furnaces, where is a need to monitor and control oxygen concentration. Instrument air (clean, dry) is used as the reference gas and span gas for calibration. Zero gas is supplied from a gas cylinder.

System 2 uses the automatic calibration unit, with auto-switching of the calibration gas. A “combustible gas detected” contact input turns off power to the heater. There’s also contact output from the analyzer that can be used to operate a purge gas valve to supply air to the sensor.
