Determination of the Installation Point
In order to maintain the accuracy stated in the technical data, the
device must be installed correctly. The gas must flow on to the sensor
tip, otherwise it will lead to wrong measurement values. For further
instructions, please read chapter 8 carefully.
Please consider that enough space exists at your site for a convenient
installation.
ATTENTION!
Wrong measurement is possible if the instrument is
not installed correctly.
•
The device is for indoor use only! At an outdoor installation, it
must be protected from solar radiation and rain.
•
It is strongly recommend not to install S211 / S215 / S220
permanently in wet environment, which usually exists right after a
compressor outlet.

8.1 Installation Requirements
The flowing air or gas must pass the sensor tip for a proper
measurement. This can be realized with a measurement chamber.
For an installation without the measuring chamber, you must insert the
device to the required depth, as described in section 8.2.
Remark:
The 3 Dew Point Transmitters models S211, S215 and S220 are offered
in different versions. Depending on the version the options might be
different, please see below table for an overview about the different
models, their signal output and available options.

In any case, if you need support to choose the right model for your
application, please feel free to contact SUTO sales support.
8.2 Installation Procedure
The following steps explain the procedure of an appropriate installation.
Installation with the measurement chamber A699 3491
1. Mount the device on the
measurement chamber by
using the G1/2” connection.
2. Make sure the device is tightly
sealed, therefore the sealing
ring on the Dew Point
Transmitter must be used.
3. Connect the measuring
chamber to the compressed
air system using a quick
connector. Make sure the Dew
Point Transmitter is screwed
on the chamber before
connecting.
The measurement chamber
will create a purge flow.

S211/S215/S220
Installation with the by-pass measurement chamber A699 3493
For the model A699 3493, there are two installation methods:
Method 1: Full pass through by-pass installation
This method is to be used when the full air flow is passing through the
measuring chamber.
1. Connect the inlet of the chamber using a 6 mm teflon hose to your
system.
Note: The full flow must pass the measuring chamber. Ensure a
certain flow rate to get fast response time.
2. Connect the outlet of the chamber to your system using the 6 mm
hose quick connector.
See below figure for details.
S211/S215/S220
17
Method 2: By-pass installation
Note : In order to use the measurement chamber in a by-pass you
must ensure a pressure difference between P1 and P2 as indicated in
the picture below.
1. Connect the inlet of the chamber to your pipe system.
2. Connect the outlet of the chamber to your pipe system where the
pressure is known to be lower than the inlet pressure.
Note : The pressure difference P1 > P2 is needed to create a by-pass
flow through the chamber. If there is no pressure difference between P1
and P2, there will be no flow through the chamber and therefore the
response time will be very slow or the device will not even respond at
all to the dew point changes.
18
S211/S215/S220
Installation without the measurement chamber
•
Install the device only if
the system is pressure-
less.
•
Please check the size of
the nozzle and make sure
not less than 1/3 of the
sensor tip is inside of the
pipe.
Full flow installation. The sensor is in
the pipe.
•
The inner thread must be
G 1/2”.
Remarks
Please install the device only in
the recommended area, as
shown in the left picture.
The angle between the device
and the centre vertical line of the
tube must be greater than 30°.
An upside down installation is not
permitted.
Removal of the Dew Point Transmitter
Unscrew the device off the measurement chamber or from the nozzle.
Please make sure that the system is pressure-less before the Dew Point
Transmitter is removed.
