YOKOGAWA ZR22G ZR402G Oxygen/Humidity Analyzer

YOKOGAWA ZR22G  ZR402G Oxygen/Humidity Analyzer

INTRODUCTION

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.

Safety, Protection, and Modification of the Product

• In order to protect the system controlled by the product and the product itself and ensure safe operation, observe the safety precautions described in this user’s manual. We assume no liability for safety if users fail to observe these instructions when operating the product. 

• If this instrument is used in a manner not specified in this user’s manual, the protection provided by this instrument may be impaired. 

• If any protection or safety circuit is required for the system controlled by the product or for the product itself, prepare it separately. 

• Be sure to use the spare parts approved by Yokogawa Electric Corporation (hereafter simply referred to as YOKOGAWA) when replacing parts or consumables. 

• Modification of the product is strictly prohibited.

Features:

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

• The probe uses a long-life, high-reliability Zirconia sensor. 

• The probe uses three-reference gas supply methods (natural air convection, instrument air, and pressure compensated) in its applications. 

• The separate type converter incorporates a LCD touchscreen for ease of operation.

• This converter can be used as an oxygen analyzer as well as a high temperature humidity analyzer. 

• The integrated type integrates both probe and converter, to reduce wiring, piping, and installation costs. This type of unit uses an optical switch for ease of operation at the site. 

• Remote maintenance using digital communications (HART) reduces maintenance costs.

Main Functions:

Zirconia sensor: adopting advanced zirconia sensor technology, it can accurately measure the oxygen content in the gas.

High accuracy: with high measurement accuracy, it can meet the needs of various industrial applications.

Good stability: the sensor performance is stable and not easy to drift in long-term use, ensuring the reliability of the measurement results.

Multiple installation methods: may support a variety of installation methods, such as fixed, portable, etc., to adapt to different testing environments.

Display and output: Equipped with an intuitive display, it can show the oxygen content data in real time and support standard signal output such as 4-20mA, which is easy to integrate with the control system.
