2. Application
2. Application
The S 120 is an oil vapor sensor which is designed to monitor oil
contents of compressed air and gases within the permissible operating
parameters. These parameter can be found in the technical data
section.
The S 120 oil vapor sensor is not developed to be used in explosive
areas. For the use in explosive areas please contact the manufacturer.
The S 120 oil vapor sensor is mainly used in compressed air systems in
industrial environment.
3. Features
•Measures oil vapor contents in compressed air and other gases.
•Easy connection through sampling hose and quick connect.
•Can be used for permanent or in portable applications.
•Measures dorm to 0.001 mg/m3.
•PID sensor for highest accuracy.
•Service and alarm indication through LED.
•Connectable to display and data logger of the manufacturer as
well as third parties displays and control units.

6. Installation
6.3 Installation Procedure
The following steps explain the procedure of an appropriate installation.
1. Connect the teflon hose with
the inlet of the S 120 like
shown in the picture.
2. Connect the other end of the
teflon hose with a quick
connector. The teflon hose
with quick connector is used
to connect the S 120 to the
process.
Please consider the following recommendations for a successful
measurement result:
•All components from the sampling point to the S 120 must oil and
grease free.
•Ambient and gas temperature must be within the specified ranges.
•The inlet gas must be pressurized with the valid ranges.
12 S 120

6. Installation
•The sampling gas mus be dry (< 40% RH) and clean.
•Ensure that valves at the sampling point are not lubricated.
ATTENTION!
Avoid contamination with oil or grease!
It will lead to very slow measurement or impossible
measurement results!
