Duct Air Velocity Sensor

1.Product overview of Duct Air Velocity Sensor

Duct Air Velocity Sensor is a device used to measure wind speed in wind ducts， It can measure air velocity quickly and accurately and is used in wind speed measurement in many fields.Duct Air Velocity Sensor is a wind speed measuring instrument independently developed and produced by our company.This product consists of a shell, impeller and circuit module, and integrates internal photoelectric conversion mechanism, industrial microcomputer processor, standard current generator, 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 and use special mold precision die-casting process.The dimensional tolerance is very small, and the surface accuracy is very high.The internal circuits are all protected.The entire sensor has high strength, weather resistance, corrosion resistance and water resistance.The cable connector is a military plug, which has good corrosion and corrosion resistance, which can ensure long-term use of the instrument.At the same time, it is used in conjunction with the internal imported bearing system of the wind speed sensor to ensure 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; all electronic components are imported industrial-grade chips, which makes the overall high-reliability of electromagnetic interference resistance, and can ensure that the host is between -30℃ and +60℃., the humidity can work normally within the range of 35% to 85% (no condensation).

2.Duct Air Velocity Sensor application scope

This product can be widely used in the fields of construction machinery (crane, crawler crane, door crane, tower crane, etc.), railway, port, dock, power plant, meteorological, cableway, environment, greenhouse, breeding, air conditioning, energy conservation monitoring, agriculture, medical care, Measure wind speed in clean space and other fields, and output corresponding signals.
