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.

7.3 Installation procedure
7.3.1 Installation requirements
Please consider the following recommendations for a successful
measurement result:
•All components from the sampling point to the S120 must be oil
and grease free.
•Ambient and gas temperature must be within the specified ranges
stated in section General data.
•The inlet gas must be pressurized with the valid ranges.
•The sampling gas mus be dry (< 40% RH) and clean.
•Ensure that valves at the sampling point are not lubricated.
TTENTION!
void contamination with oil or grease!
It will lead to very slow measurement or impossible
measurement results!
•Make sure that there is no rough contaminants at the point of
measurement. Steps are as follows:
1. Connect the purge filter test kit onto your measuring point
first. Open the purge valve on the test kit and purge air for a
short period.
2. Check the filter in the test kit to see whether it shows high
contamination of water, oil or dust.
3. If the filter is contaminated severely, stop using the S120 for
measurement because this may lead to serious damage to the
device. In case you are not sure, please contact the
manufacturer.

7 Installation
TTENTION!
Before you connect the device to your point of
measurement, make sure that there is no rough
contamination like water/oil drops or heavy dust.
This may damage the sensor units. For this please
use the purge filter test kit.

7.3.2 Installation steps
The following steps e plain the procedure of an appropriate installation.
Most importantly, before you connect S120 to the compressed air,
purge air out from the measuring point to remove any residual
contamination using the purge filter test kit.
1. Connect the teflon hose with
the inlet of the S120 as
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 S120 to the
process.
