3 Application
3 pplication
The S120 is an oil vapor sensor which is designed to monitor oil
contents in compressed air and gases within the permissible operating
parameters. These parameters can be found in the technical data
section.
The S120 oil vapor sensor is mainly used in compressed air systems in
industrial environment. The S120 oil vapor sensor is not developed to
be used in e plosive areas. To evaluate its applicability in e plosive
areas, please contact the manufacturer.
4 Features
•Measures oil vapor contents in compressed air and other gases.
•Easy connection through sampling hose and quick connect.
•Applicable in the permanent or portable applications.
•Measures down to 0.003 mg/m3.
•PID sensor for the highest accuracy.
•Service and alarm indication through LEDs.
•Connectable to display and data logger of SUTO as well as third-
party display and control units.
•IP65 casing provides robust protection in rough industrial
environment.
•Optional local display for showing actual readings without e tra
cable connection.
