Cup Anemometer PCE-A420

Description
Cup Anemometer PCE-A420 for Wind Speed Measurement

Introduction:

The PCE-A420 serves as a cup anemometer designed for precise wind speed measurements. Three spherical cups, arranged horizontally on the vertical axis, record wind speed by rotating with the wind’s force. The rotation speed of the cups determines the wind speed, providing a simple and effective measuring principle.
Advantages over Impeller Anemometers:

Compared to standard impeller anemometers, the PCE-A420 offers a notable advantage. Wind direction becomes less critical, as the cup anemometer doesn’t require precise alignment with the wind. The orientation of the half-cups enables the cup star to move independently of the wind direction, ensuring accurate measurements even at low flow velocities.

Measurement Range and Units:

With a resolution of 0.1 m/s or 0.1 km/h, the cup anemometer’s measuring range spans from 0.9 m/s to 35 m/s or 2.5 km/h to 126.0 km/h. It provides flexibility by offering units in m/s, km/h, knots, miles/h, and ft/min.

Features and Display:

The anemometer records rotations per minute, displaying wind speed on a convenient LC display (28 x 19 mm). Maximum and minimum values are stored, accessible on the display. The Data-Hold function preserves the last measurement results, complemented by a practical 100-point data logger. The device, marked IP 65, is protected against dust and moisture, ensuring durability.

Applications:

Weighing a mere 180 grams with a compact plastic housing, the PCE-A420 proves highly mobile and adaptable. Its applications range from ventilation control in factories using a pitot tube to on-site wind speed measurements, providing accuracy up to 35 m/s. The anemometer is ideal for swift and precise ground-level wind speed checks, making it indispensable in various scenarios.

Auto-Power-Off and Battery Conservation:

Equipped with an Auto-Power-Off function, the cup anemometer conserves battery life during periods of inactivity, shutting down automatically after a brief duration.

Understanding Cup Anemometers:

Derived from the Greek word “Ánemon” meaning wind, anemometers measure wind speed. The cup anemometer, with its vertical axis and rotating cups, exemplifies the common application. The faster the wind, the quicker the cups rotate, with electronic recording facilitating accurate wind speed measurement.

Measuring Principle:

The PCE-A420’s measuring principle is straightforward: the rotational speed of the half-open plastic cups corresponds to wind speed. Electronic recording captures the number of revolutions per minute, providing a reliable measure of wind speed.

In summary, the PCE-A420 cup anemometer stands out for its accuracy, flexibility, and ease of use, making it an essential tool in various fields requiring precise wind speed measurements.
