ZR22G, ZR402G Separate type Zirconia Oxygen/Humidity Analyzer

ZR22G, ZR402G разделенный анализатор оксида магния и кислорода / влажности

Introduction

Thank you for purchasing the ZR22G, ZR402G Separate type Zirconia Oxygen/Humidity Analyzer. Please read the following respective documents before installing and using the ZR22G, ZR402G Separate type Zirconia Oxygen/Humidity Analyzer

An exclusive User’s Manual might be attached to the products whose suffix codes or option codes contain the code “Z” (made to customers’ specifications). Please read it along with this manual. The EXAxt ZR Separate type Zirconia Oxygen/Humidity Analyzer is usually the Oxygen Analyzer which connected ZR402G converter and ZR22G detector together, but it is to the High Temperature Humidity Analyzer when the option code “/HS (Set for Humidity Analyzer)” of ZR402G is selected.After that, in this manaul, the Humidity Analyzer refers to the thing which ZR22G combined with ZR402G with “/HS”.In addition, in this manual, the Oxygen Analyzer is mainly listed. When there are not mentions 

such as “in the case of Humidity Analyzer”, it becomes same as the Oxygen Analyzer.The EXAxt ZR Separate type Zirconia Oxygen/Humidity Analyzer has been developed for combustion control in various industrial processes. This analyzer basically consists of a detector and a converter. You can select between several versions, based upon your application. Optional accessories are also available to improve measurement accuracy and automate calibration. An optimal control system can be realized by adding appropriate options. This instruction manual refers to almost all of the equipment related to the EXAxt ZR. You may skip any section(s) on the equipment which is not included in your system. Regarding the HART communication protocol, refer to IM 11M12A01-51E. IM 11M12A01-51E has been published as “Model EXAxt ZR Series HART Protocol” . The Integrated type (with sensor and analyzer integrated in one body) is described in  IM 11M12A01-04E.

For the safe use of this equipment

WARNING

Handle it with care. Be sure not to accidentally drop it. Handle safely to avoid injury. Connect the power supply cord only after confirming that the supply voltage matches the rating of this equipment. In addition, confirm that the power is switched off when connecting power supply. Some sample 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

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

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

 • Avoid any water dropping directly on the probe (sensor) of the detector 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 detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.

NOTICE

l Specification check When the instrument arrives, unpack the package with care and check that the instrument has not been damaged during transportation. In addition, please check that the specification matches the order, and required accessories are not missing. Specifications can be checked by the model codes on the nameplate.
