Technicaldata
Type 8011
Protection against
polarity reversal yes
Protection against
spike voltages
yes
Protection against
short circuits yes, for the pulse outputs
Pulse output
• Version with 1
pulse output
• Version with 2
pulse outputs, NPN
and PNP
transistor
• open collector, 20 mA max., NPN output:
0,2-24 V DC, frequency up to 300 Hz
(frequency = K factor x flow rate).
• open collector, 700 mA max., frequency
up to 300 Hz (frequency = K factor x
flow rate), NPN output: 0,2-36 V DC and
PNP output: Supply voltage
6.3.4. electrical connections
Version type
With a cable gland Cable, 1 m
With a fixed connector Male 5-pin M12 fixed connector
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
