4.1 Application in Extreme Environment
When handling the Differential Pressure Sensor, it is important not to add any small objects into the two flow channels on
top of the sensor. The sensor is specified for operation in air, N2 or O2. Avoid aggressive or etching substances such as H2O2
or NH3.
Liquid
Avoid any kind of liquid, fatty and oil emulsive vapors inside the flow channel. If exposed to such conditions, it cannot be
guaranteed that the sensors have no drift.
Condensation
Avoid condensation inside the sensor. After condensed water has completely evaporated, the sensor will be fully functional
again.
Dust
Protect the sensor from dust, which could enter into the flow channel.

5 Setup of Eupry Differential Pressure Sensor
Connecting to your Eupry Data Logger
Connect the Eupry Differential Pressure Sensor to the socket on the top face of a Data Logger. Make sure that the connector
is firmly pressed all the way in until you hear a clicking sound or feel a haptic feedback.
6 Product Identification
All Eupry Differential Pressure Sensor have two forms of identification:
Unique serial number
A unique serial number of the Differential Pressure Sensor is written as text on the label of the sensor and can be used to
identify the unit in Eupry’s system.
Unique GRAI code datamatrix
A unique GRAI code identification, which also includes the serial number of the Differential Pressure Sensor, is placed on the
label as a data matrix.
The entire GRAI code (GS1 standard) uniquely identifies the sensor internationally and can be used with GRAI compliant
systems.
7 Cleaning guide
When cleaning the sensor, it is very important not to spray any cleaning soap or alcohol inside the two flow channels.
Please only clean the sensor by spraying on a cloth and wipe the sensor.

8 Appendix FAQ
8.1 I have got multiple alarms during the connection process
It is completely normal to get alarms during these processes as the sensors you are connecting are at room temperature
when first plugged in. Be aware that you do not continue to get these alarms.
8.2 The light does not turn on when I press the Eupry Button
Look at the user manual for the Data Logger on support.eupry.com.
8.3 The Data Logger does not light green when I release the button
Look at the user manual for the Data Logger on support.eupry.com.
8.4 Where can I see the ID of the Data Logger and ID of the External Sensor?
We have two kinds of barcode labels. The two pictures below illustrate where the ID can be found.
The ID of this Data Logger is the last four digits on the side of the Data Logger. The ID of the sensor is the digits on it (see
figure).
The ID of this Data Logger is the last five digits on the side of the Data Logger. The ID of the sensor is the digits on it (see
figure).
