description
Temperature (optional):
• Sensor directly
• Analogue output
*2) Resolution 7 bit or 10 bit (depending on version).
*3) Resolution 12 bit.
*4) other scales possible.
*5) Dual slope measurement method with basic accuracy ±0.5 K.
*6) Dual slope measurement method with basic accuracy ±1.0 K.
4.1.1 Flow Measurement
VVX with frequency output:
Depending on the version, the VVX provides
a flow-proportional NPN, PNP or push-pull
square-wave signal.
The frequency of the frequency output
changes with the flow ( Fig.).
VVX with analogue, voltage or current out-
put (optional):
The output of the VVX is either the voltage U
The output signal is proportional to the measured flow. The scaling of the output is indicated
on the type plate and on p. 25.
4.1.2 Temperature Measurement (Optional)
The temperature is measured by an additional sensor R
tube.
Depending on the version, this is an NTC or Pt1000.
For the VVX with analogue output (0.5...3.5 V), the voltage signal U-Temp can also be meas-
ured. The scaling of the output is indicated on the type plate and on p. 25.
