4.2 Installation of the Detector (Model ZR22G-015-Q)

Note: Ceramic (Zirconia) is used in the sensor (cell) portion of the detector probe. Care should be
taken to not drop the detector during installation. The same applies to the High Temperature Adapter
transport tube.
A gasket should be used on the flange surface to prevent gas leakage. The gasket material should be
selected depending on the characteristics of the measured process sample gas. It should be heat and
corrosion resistant to the sample temperatures and gases present. These parts are to be supplied by
the user, and are described in Table 4.1.

Installation Location

The ZR22G-015-Q model detector is used with the ZR22P High Temperature Probe Adapter, when
sample gas temperatures exceed 700ºC (1292ºF). Additionally, this detector can be utilized where
maintenance space is limited.
