Technicaldata
Type 8012
6.3.3. electrical data
Power supply 12-36 V DC, filtered and regulated
Current consumption max. 60 mA (at 12 V DC for the version
with current output - no load)
Protection against
polarity reversal yes
Protection against
spike voltages yes
Protection against
short circuits yes, for the pulse output
Pulse output transistor, NPN by default (can be confi-
gured as PNP, on request), open collector,
700 mA max., NPN output: 0,2-36 V DC
and PNP output: supply voltage, frequency
up to 300 Hz (frequency = K factor x flow
rate). Configurable on request
Current output
(depending on
version)
• max. loop
impedance
4-20 mA, sinking wiring by default, equals
the rotation frequency of the paddle-wheel
(by default). Configurable on request
• 1125 W at 36 V DC
• 650 W at 24 V DC
• 140 W at 12 V DC
6.3.4. electrical connections
Version type
With a cable gland Cable, 1 m
With a fixed
connector 5-pin M12 fixed connector, adjustable in
position
6.3.5. K factors
The K factors have all been determined in the following reference
conditions:
medium = water, water and ambient temperatures 20 °C, min. upstream
and downstream distances respected, appropriate pipe dimensions
Two versions of the S012 in DN15 and DN20 exist, having
different K factors.
Only version 2, identified by the "v2" marking, is available
from March 2012. The "v2" marking can be found:
• on the bottom of the DN15 or DN20 fitting in plastic:
V2
• on the side of the DN15 or DN20 fitting in metal:
V2
