- The portable anemometer provides fast accurate readings with
digital readability and the convenience of
a remote sensor separately.
- Multi-functions for air flow measurement:
m/s, km/h, ft/min, knots.
- Low-friction ball-bearing design resulting in accuracy at both
and low velocities.
- Conventional twisted vane arms, always a source of unreliability
- DATA HOLD.
- Compact housing cabinate.
- Wide applications: use this anemometer to check air conditioning
& heating systems, measure air
velocities, wind speeds, temperature…etc
PRINCIPLE OF OPERATION:
MAW 2300 wind vane is a counter balanced, low threshold wind vane. A
Linear, wire wound endless potentiometer is coupled to the vane by
an SS shaft. As the vane turns, it rotates a stainless steel shaft
which is coupled to the potentiometer. This
potentiometer has excellent linearity, very low starting torque.
The north of the wind vane is marked on its body. This line is to be aligned with actual North with the help of prism atic compass, at the time of installation. Sensor gives minimum resistance at North (i.e., 0 degree approximately 20 ohms ). The resistance output linearly proportional to the position of the wind vane
