Mainstream entry aerial drone shopping guide--Dajiang Phantom 3

大疆Phantom 3 Professional首

Background: Dajiang is a domestic drone manufacturer. It is unknown in the field of drones, with a market share of over 50%. Phantom 3 is the third generation of Dajiang's entry-level entertainment-class drone products . It has a high technical content and can be said to be the industry benchmark.

Product introduction: Dhanjiang Phantom 3 is a small four-axis drone with a wheelbase of about 330mm and a 9-inch propeller. The Phantom 3 is available in two versions, one for Professional and the other for Advanced, the former with a 4K camera and a 100W charger with a 1080p camera and a 57W charger (charger power affects charging speed). Other than that, there is no difference between the two. Phantom 3 Pro is priced at $7,499 and Phantom 3 Adv is priced at $5,999. Personally feel the difference between the two is slightly pitted, the difference of 1,500 yuan is reflected in the camera and charger, whether it is worth only according to personal needs.

There is no big problem in the overall function of Dhan Phantom 3. High-definition digital image transmission, three-axis stabilization cloud platform, GPS+GLONASS dual satellite positioning are the industry leading technologies. However, the official blowing of the indoor visual positioning function in the sky has many restrictions (carpet, ceramic tiles can not be used), battery cell damage speed is too fast, the new firmware affects stability, etc. are many users actually encountered and reflected The problem, so Phantom 3 has not yet become a perfect product.

to sum up:

The above four consumer-grade aerial drones have their own advantages and disadvantages, and the prices are not the same. When you choose, you can pick according to your own needs. For example, if you want to match GoPro, choose Zero XPLORER. I hope that the above content can clarify the situation of consumer-grade drone products.

Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material

 

Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51. 

 

Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs.  Yuhai  hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4. 


Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
