The Yokogawa ZR22G is a Zirconia Oxygen/Humidity Analyzer that is used to measure the concentration of oxygen and humidity in gases. It is a versatile instrument that can be used in a variety of applications, including:
-
- Combustion control in boilers and furnaces
- Process control in chemical and petrochemical plants
- Emissions monitoring
- Environmental monitoring
The ZR22G is a two-wire transmitter that uses a zirconia sensor to measure oxygen concentration. The zirconia sensor is a solid electrolyte that allows oxygen ions to pass through it. The rate at which oxygen ions pass through the sensor is proportional to the oxygen concentration in the surrounding gas.
