General Use Separate Type Detector And Related Equipment; Zr22G General Use Separate Type Detector - YOKOGAWA ZR22G User Manual

2.2 General use Separate type Detector and
Related Equipment
General use separate type detector ZR22G can be used in combination with the probe protector
ZO21R (see Section 2.2.2).
In case of Humidity Analyzer, the "Detector with dust protector" consists of ZR22G general-use
separate-type detector and ZH21B dust protector (refer to Section 2.2.3).

It is necessary to mount the cell using Inconel cell-bolts when the
temperature is greater than 600°C.
700 to 1400°C (with High Temperature Probe Adapter)
For high temperature sample gas (700 to 1400°C), apply 0.15 m long
probe and High Temperature Probe Adapter ZO21P.
recommended to use pressure compensated type. When the pressure
in the furnace exceeds 5 kPa, pressure compensated type is required.)
For 0.15 m probe, -0.5 to 5 kPa. No pressure fluctuation in the furnace
should be allowed.
No pressure fluctuation in the process should be allowed.
In case of Humidity Analyzer, -5 to 20 kPa
Note: When the detector is used in conjunction with a check valve and a ZA8F Flow Setting Unit, the
maximum pressure of sample gas is 150 kPa. When with a check valve and a ZR40H Automatic
Calibration Unit, it is 200 kPa. If the pressure of your sample gas exceeds these limits, consult with
Yokogawa.
