INSTALLATION

The M&C probes SP3110 and SP3110V have been developed for stationary use. With correct
selection and installation, they will guarantee many years of trouble-free service with a minimum of
maintenance.
We recommend a horizontal mounting position with the sample gas outlet showing downwards (this is
not absolutely essential for proper functioning of the probe). The probe should be installed with an
inclination of approximately 10° with respect to the process.
Warning
Work on the gas sample probe may only be carried out by qualified personnel
Qualified
when the process and environment have been declared to explosion-free zones,
personnel
i.e. they are free of explosive atmospheres.
