Choosing the Appropriate Mounting Location
• The mounting location site shall be easily accessible and free of vibration.
• A minimum clearance of 150 mm (5.9") shall be observed around the mounting location for
installing / removing the sensing unit of the EE741.
• The ambient temperature shall not exceed the specified limits. Consider also the possible heat
radiation.
• Air (medium) purity at the mounting location shall comply to ISO 8573-1:2010, at least Class
3.4.4.
• The medium and the ambient conditions at the mounting location shall be non-condensing.
• In compressed air networks, EE741 shall be installed after the air dryer. In the absence of a
dryer, EE741 shall be installed after the condensate separator and appropriate filters.
• Observe the flow direction in the pipe.
• Observe the recommended inlet and outlet path length. These are relevant for measurement
accuracy as specified in the EE741 data sheet.
• EE741 shall be located as far as possible from flow disturbances, for instance at an
appropriate distance before valves.
4.2.1
Process Pressure
The pressure in the pipeline may not exceed 16 bar (232 psi).
Before mounting or removing the sensing unit, the pipeline must be depressurised.
Due to its measuring principle, the measurement accuracy of the EE741 is quasi-independent
of the actual process pressure. Besides, the device is factory adjusted at 7 bar (102 psi)
absolute pressure. For normal requirements pressure compensation is not necessary. For best
measurement accuracy, the actual working pressure can be set via display menu, via EE-PCS
Product Configurator Software or via the IO-Link interface.
4.3
Installation Position
The suitability of the following mounting positions must be taken into account for mounting the
EE741 in the gauge mounting block or in the gauge mounting block with flanges.
