Parameter settings
Settings for vane wheel sensors FA:
5.3.1
FA - Basic settings
Menu -> Settings -> Sensor -> FA input ->
Basic settings
The connected
vane wheel sensor
determines the parameter type, measuring range, material and direc-
tional sensing to be set.
5.3.1.1
Type
Setting the vane wheel type:
This can be determined from the serial no. on the sensor.
Selection:
mc
=
micro -
for use in for instance:
cylinder probes with OD 14, 16, 18 mm
measuring tubes with ID 9.7 mm
mn
=
mini
for use in for instance:
cylinder probes with OD 25 mm
measuring tubes with ID 18.2 mm
md
=
midi
for use in for instance:
cylinder probes with OD 30 mm
pairs of values
= special calibration characteristic specifically matched to the
measuring task based on up to 30 supporting points. Input or
changing the points, see under 5.3.6
Distinctive feature of sensors with vane wheel types
md3
and
ms
(measuring tube):
These sensors are always supplied with a special calibration characteristic. Therefore, always select
pairs
of values
. For input or change see (5.3.6) pairs of values.
5.3.1.2
Range
Setting the vane wheel measuring range:
This can be determined from the serial no. on the sensor.
Selection:
20
= measuring range up to
20 m/s
40
= measuring range up to
40 m/s
80
= measuring range up to
80 m/s
120
= measuring range up to
120 m/s
Exceeding the measuring range can cause permanent damage to the vane wheel!
5.3.1.3
Material
Setting the vane wheel sensor material:
This can be determined from the serial no. on the sensor.
Selection:
steel
=
E
aluminium
=
A
titanium
=
T
5.3.1.4
Directional sensing
Setting the directional sensing function: such sensors are identified by an "R" in the serial number.
Selection:
Y
= directional sensing
yes
, measured value display
with prefix
N
= directional sensing
no
, measured value display
without prefix
