Duct Air Velocity Sensor

1. Duct Air Velocity Sensor Product Overview

Duct Air Velocity Sensor used to measure gas wind speed, with air volume calculation function, and obtain the standard wind speed and standard volume air volume.Duct Air Velocity Sensor is a wind speed measuring instrument independently developed and produced by our company. This product consists of a casing, an impeller and a circuit module. It integrates a photoelectric conversion mechanism, an industrial microcomputer processor, a standard current generator, a current driver, etc. (This product is divided into pure stainless steel and plastic fan blades for customers to choose from)

The sensor housing and impeller are made of stainless steel, using a special mold precision die-casting process. The dimensional tolerance is very small and the surface precision is very high. The internal circuits have been protected. The entire sensor has high strength, weather resistance, anti-corrosion and waterproof properties. The cable connector is a military plug, which has good anti-corrosion and anti-erosion properties, ensuring long-term use of the instrument. At the same time, the imported bearing system inside the wind speed sensor ensures the accuracy of wind speed collection.

The circuit PCB uses military-grade A-grade materials to ensure the stability of parameters and the quality of electrical performance; the electronic components use imported industrial-grade chips, which makes the whole body extremely reliable in anti-electromagnetic interference and can ensure that the host temperature is -30℃~+60℃ , it can work normally within the humidity range of 35% to 85% (no condensation).

2. Application scope of Duct Air Velocity Sensor

This product can be widely used in the fields of construction machinery (cranes, crawler cranes, gantry cranes, tower cranes, etc.), railways, ports, docks, power plants, meteorology, ropeways, environment, greenhouses, breeding, air conditioning, energy-saving monitoring, agriculture, medical care, Measure wind speed in clean spaces and other areas, and output corresponding signals.

3. Duct Air Velocity Sensor technical parameters
