，according to the packing list to check the number of instruments and accessories are complete。
øif the instrument is found to have been damaged during transport, the carrier and supplier should be notified immediay. do not damage the instrument back to the consignor, otherwise the carrier will not be compensated. keep the box and damaged parts for carrier inspection.
the instrument has been accuray calibrated before shipment and no further calibration before installation.
failure to follow the operating instructions for the use of an oxygen analyzer may result in unnecessary danger.
before making electrical connections, make sure that all wires are insulated and that the power cord and signal cable are connected in strict accordance with the operating instructions to avoid electric shock.
ø the protective ground on the power plug must be well grounded to ensure operator safety. oxygen analyzer before the first start, the ground must be checked to ensure that the wire without interruption.
special protective measures must be taken when operating on high pressure vessels. when working on high temperature containers and pipes, remember to wear protective masks to protect your face and eyes from harm.
in the vicinity of high temperature containers and pipes must wear protective clothing, wearing protective gloves, to ensure safety.

pay attention to high temperature
oxygen analyzer for boiler, kiln flue gas oxygen content (concentration) of continuous detection, the system uses non-sampling (wet) analysis.
the integrated zirconia oxygen analyzer consists of a detection unit (oxygen probe) and a control unit (transmitter). wherein the detection unit is installed on the flue and is equipped with a temperature control unit and a zirconia sensor; the control unit is a terminal for the user to operate the integrated function, including an operation panel, a display interface, and a 4-20ma current output port.
the probe part is made of stainless steel, durable, standard configuration length of 1.0m, according to user needs to provide a length of 0.2m ~ 2.0m probe.
the analyzer is not properly serviced and is wired correctly according to the wiring diagram. analyzer installation is simple and convenient, installed in the high temperature flue work, should pay attention to take the appropriate security measures. 。
oxygen analyzer
split oxygen analyzer is divided into two parts: analysis and detection unit and control unit.
control unit (transmitter) shell for the cast aluminum, the shell has a control circuit.
control unit specification
the control unit should be installed in locations where vibration and high temperatures should be avoided. strong vibration and high temperatures can have a significant impact on the life of the instrument.
tfzo-5/05yt-gdxygen analyzer analysis unit the probe section is made of stainless steel, the head shell is cast aluminum, and the housing has an electrical connection terminal. in addition, the external reference air and calibration gas inlet and exhaust are also located on the cast aluminum housing.
oxygen analyzer detection units with standard lengths of 0.5m, 1.0m and 1.2m are available. other specifications can be customized production.
analysis of the detection unit specifications
ø
1、the flue gas temperature of the test unit installation point should meet the relevant requirements. generally speaking, the flue gas temperature is low, the detector has long service life, high flue gas temperature and short service life. flue gas temperature is best at 300-600 °c.
2、the detection unit can not be installed in the flue gas does not flow dead, can not be installed in the flue gas flow quickly (such as some bypass airway expansion chamber).
3、requiring the flue leakage is small, the detector installation and maintenance convenience, for small and medium-sized boilers, it is recommended to install the preheater in the economizer, because the boiler system flue gas flow from the furnace to the drum, after the superheater, the air preheater is discharged from the chimney by the draft fan after recycling. if the measuring point is too close to the flue gas furnace outlet, because the temperature is too high, the flow rate is quick, the detector stainless steel shell will form erosion erosion, shorten the service life; if the measuring point is too partial, due to flue system leakage phenomenon, will result in high oxygen value at the measuring point, can not accuray reflect the furnace oxygen in the flue gas.
the oxygen analyzer can be mounted via a flange, including：
equipment installation flange：
equipment installation flange specifications
oxygen analyzer welding equipment has been installed flange, aperture 4 ×φ14mm, screw hole spacing of 130mm.
ø adapter flange mounting short connection：
adapter flange mounting shorting
made in the form of a fitted flange, it is suitable for flue with flanged flanges on flue.
wearable casing specifications
the use of corrosion-resistant casing flange installation, suitable for all the structure of the flue, aperture 4 ×φ14mm, screw hole pitch of 130mm.
use sleeve flange to install
[1] in the flue to open a diameter and casing diameter of the hole.
[2]place the casing on the flue and leave enough space to insert and tighten the safety bolts.
[3]install the flange gasket and insert the oxygen analyzer.
[4]insert the safety bolts from the rear end of the sleeve flange into the sleeve flange, flange pad and device mounting flange, and install the upper and lower nuts and nuts.
ø install the flange and the weld is coated with anti-corrosion protective layer, can not be removed. the installation will be different from the installation steps, such as flue with a welding flange, the user will need to bring their own parts.
