Yokogawa Zirconia Oxygen Analyzer ZR202G-100-S-C-N-C-T-M-E-A/SCT/H
This analyzer consists basically of a probe and a converter that are used as both a Zirconia Oxygen Analyzer and High Temperature Humidity Analyzer. The probe is of direct insertion type, and the converter uses a digital display.
Two types of analyzers are available: separate type and integrated type. As its name implies, the integrated type combines probe and converter.
Separate and integrated type Zirconia oxygen 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. The converter displays the cell temperature and cell emf in addition to the oxygen concentration.
This analyzer is most suitable for monitoring the oxygen concentration of combustion gases in large or small boilers, various industrial furnace and combustion devices, or for the control of low-oxygen combustion.
Separate type and integrated type Zirconia High Temperature Humidity Analyzers are used to measure the humidity of hot gases continuously in driers which use an electrical heater or hot gas as the heat source.
They can also be used in a variety of manufacturing applications in humidifiers, as well as in driers, for humidity measurement and control. They can help improve productivity in these application fields.
Yokogawa Zirconia Oxygen Analyzer ZR202G-100-S-C-N-C-T-M-E-A/SCT/H
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 touch screen 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.
