3 Application
3 Application
The S520 is a dew point meter that is designed to monitor the dew
point in the industrial application within the permissible operating
parameters. These parameters can be found in the Technical data
chapter on page 9.
The S520 can measure and display the following values for compressed
air or gas:
•Dew point, default unit: °C Td
•Humidity, default unit: °C Td
•Temperature, default unit: °C
•Pressure, default unit: bar (g)
The S520 dew point meter is mainly used in compressed air systems in
industrial environments. It is not developed to be used in e plosive
areas. For the use in e plosive areas please contact the manufacturer.
4 Features
•Measures dew point, temperature, humidity, and pressure
•Two sensor solutions available:
◦Sensor A: Standard sensor unit with a range of
-100 … +20°C Td
◦Sensor B: Economic sensor unit with a range of
-50 … +50°C Td
•Smart dew point prediction
•Integrated pressure sensor
•Modern colour touch screen interface
•Data logger, USB interface, and Bluetooth connection to a portable
printer
•Measuring/parking chamber, designed for fast sensor response
•Application software included
•Integrated camera for more elegant reports
•ISO8573-1 Class indication

Installation
7.1 Installation procedure
The following steps e plain the procedure of an appropriate installation.
1. Make sure that the teflon hose is dry
and clean.
Attention:
Wet and contaminated hoses can
negatively affect the measurement and
must be replaced with a dry and clean
one.
2. Connect the teflon hose to the
measuring chamber.
3. Connect the quick coupling at the other
end of the teflon hose to the process.
S520 13

Installation
5. Turn the handle on the chamber to the
“Measuring” position.
Note: The parking measuring chamber is
mounted permanently on the sensor head
to keep the sensor dry. To measure, the
handle on the chamber must be turned
into the “Measuring” position.
After finishing the measurement, please
turn it to the “Park” position.
6. Turn on the device.
7. Start to measure using the touch screen. For more information, see
Chapter 8 Operation.
7.2 Electrical connection
Please charge the dew point meter if the battery is low. To do so, use
the charger that is included in the delivery package.
1. Connect the USB cable to the device and the charger.
2. Plug in the charger to your AC supply outlet.
The device starts to indicate the charging progress. Always try to
charge to 100%.

7.3 Replacing the sensor unit
For service or calibration, the sensor units can be e changed easily.
Before e changing the sensor units, please make sure that the new one
has the dew point range that matches your need:
•Sensor A: -100 … +20 °C Td
•Sensor B: -50 … +50 °C Td
To e change the sensor units, follow the below steps:
1. Open the two screws at the back of
the instrument.
2. Pull the sensor unit together with the
measuring chamber out of the main unit.
3. Screw the measuring chamber off the
sensor unit.
4. Screw the measuring chamber onto
the new sensor unit.
5. Insert the new sensor unit together
with the measuring chamber back to the
sensor unit.
6. Tighten the two screws.
