6. Mounting the Sample Inlet Unit
WARNING
◇
Turn off the power (DC24V) before mounting. Electrical shock
may occur if the unit is mounted with the power connected.
CAUTION
◇
Ensure that the prism is clean and free of any damage and/or
scratches. Completely remove any sample before installing the
CM-
BASEα to piping or equipment.
When installing the CM-
BASEα, be sure to note the following points.
①
The size of the prism stage of the CM-
BASEα is a 3S ferrule.
②
Install the CM-
BASEα so that the prism surface is at a right angle to the ground.
③
Connect the unit to the piping so that the sample flow directly contacts the prism
surface. The direct flow of samples (and self cleaning solutions) in contact with the
prism will keep substances from adhering to the prism surface.
④
The sample solution must remain in the temperature range of 10 to 50 ˚C.
⑤
During operation, build up of solids, dirt and/or grease may form on the prism surface.
When this occurs, the prism surface must be manually cleaned (See page 22.). For
ease of cleaning, the CM-
BASEα should be installed in such a manner so that the unit
can be easily removed from the piping or solution tank.
Sample inlet units are available as pipe fittings: straight type and L type.
The straight type should be installed on straight sections of piping. The L type inlet
should serve as the joining piece for piping intended to align in an L shape.
There are three ways to connect a sample inlet to a pipe: IDF/ISO clamp union (ferrule),
IDF/ISO screw union (screw), and JIS Flange.
Other sample inlets available include small diameter series compression fitting (oute r
diameter 10mmφ) and hose connector (outer diameter 12mmφ).
