3 Functions and features
The unit monitors the standard volume flow of compressed air in industrial use�
It detects the 5 process variables flow velocity, volumetric flow quantity, consumed
quantity, medium temperature and pressure�
All indications apply to standard volume flow to DIN ISO 2533, i�e� volume flow
at 1013 mbar, 15 °C and 0 % relative air humidity� The unit can be set to different
standard conditions
�
This is a class A product� This product may cause radio interference in
domestic areas�
►
If required, take appropriate EMC screening measures�
4 Function
• The volumetric flow is monitored by a calorimetric measuring system, the
measured signals are evaluated by the electronics�
• The unit detects the pressure and the media temperature as additional process
values�
• The unit features an IO-Link interface
• The unit displays the current process values�
• The unit has many self-diagnostic options�
• A simulation mode allows simplified set-up of the sensor�
4.1 Processing of the measured signals
The unit generates 2 output signals according to the parameter setting:
OUT1: 7 selection options
-switching signal for volumetric flow quantity limit
-switching signal for temperature limit
-switching signal for pressure limit
-switching signal for preset counter
-pulse signal for quantity meter
-IO-Link
-OFF (output switched to high impedance)
OUT2: 10 selection options
-switching signal for volumetric flow quantity limit
