PCE-A420 cup vane anemometer
digital cup vane anemometer, wind
direction will not influence the measurement
|
|
Without a
doubt, the main advantage of this handheld
cup vane anemometer is that it doesn't need to be held
exactly in the direction of the wind. Anemometer with
impellers normally have to be held exactly in the
direction of the air flow to take accurate measurements.
The sensitivity of the system of a cup vane anemometer responds to
the smallest of air currents. At this
link you will
find other anemometer with memory and an interface for
connectivity to a computer and software to allow for
data transfer. This
link has similar anemometers but
with a measurement range of up to 45m/s.

To perform a correct measurement with the
PCE-A420 cup vane anemometer: First turn the meter on, then hold the meter
vertically so the cups can rotate until the wind velocity is displayed. In
the following picture you can see how to measure wind speed with the PCE-A420
cup vane anemometer.
As it has previously stated, with the PCE-A420 cup vane anemometer different
measurement units can be selected: m/s, km/h, knots, ft/min and mph. To
change measurement units in the PCE-A420 cup vane anemometer you must press
the key Data Hold until the desired unit is displayed, then depress the key.
You can save the unit in the memory of the PCE-A420 cup vane anemometer to be
displayed every time the meter is turned on. In case of the messages Hold or
REC appear in the display you cannot change the measurement units. Besides,
you could fix a value in the PCE-A420 cup vane anemometer by pressing the
Hold key during the measurement. To deactivate this function please press the
Hold key again. |

ISO
Calibration and certification
An ISO calibration certificate can be acquired with
our cup vane anemometer. It includes a control document containing the
company contact details consisting on a laboratory calibration and a
certification to meet ISO standards. This means that the cup vane anemometer
meets the minimum requirements of the national body of measurement and it can
be included in your internal set of measuring instruments. Further
information:
Calibration: Control of measurement
magnitudes correction of measuring instruments without the intervention in
the measurement system, or the determination of the systematic display
deviation in relation to the real value of the measuring magnitude.
Calibration document or certificate:
document with the technical properties of the device according to the
national organization of measurement.
Calibration interval: to perform
correct measurements, devices must be calibrated at regular intervals. This
period of time is called calibration interval. It's difficult to
determine this period with accuracy but you should consider the following
factors:
·
Measuring magnitude and permitted tolerance limit
· Performance of the measuring instruments
·
Frequency of use
·
Operating conditions
·
Previous calibrations stability
·
Measuring accuracy required
·
Determining factors of the quality control systems
used by companies
This means that the user is in charge to check and
control the interval between calibrations. We recommend that this internal
between calibrations should be between 1 and 3 years. We can also offer our
expert advice to solve any doubts relating to the process of establishing a
calibration interval. |
