Operating principle
Air Velocity: Hall Effect Sensor
The rotation of the vane probe activates a circular magnet with 8
poles. A dual Hall effect sensor positioned near the magnet detects
changes in the polarity of the magnetic eld. The sensor’s output is
converted into an electrical frequency, which is proportional to the
rotation speed of the vane probe. The timing of the signals also helps
determine the direction of rotation.
Maintenance
We provide calibration, adjustment, and
maintenance for your instruments to en-
sure consistent measurement quality.
As part of our Quality Assurance Stand-
ards, we recommend conducting an an-
nual check-up.
Thermometer: NTC probe
Negative temperature coefcient probes are thermistors with a re-
sistance that decreases with temperature according to the equation
below:
RT = resistance sensor value at temperature T
R(T

Certicates
Calibration Certicate
Involves comparing an instrument’s values to a standard to
determine measurement errors and associated uncertainties.
A calibration certicate ensures that measurements are trace-
able to national standards.
Adjustment Certicate
A document that veries a device’s conformity with the tol-
erances specied in its data sheet. It conrms that the device
has adhered to the manufacturing process.
