The difference between the programmable controller of the constant temperature and humidity test chamber!

At present, the control mode of constant temperature and humidity test chamber is basically controlled by single chip microcomputer(The early simple form is basically so) andPLCmodule to control, where itsPIDAnd the dry and wet ball calculation method is a reflection of a company's software development capabilities! At present, the constant temperature and humidity test chamber on the marketControl SystemIt is mainly divided into three categories:

1.Finished product temperature and humidity controller,such as Korea.TThe prefix, JapanOprefix,There are also some domestic manufacturers, etc., which are professional suppliers of temperature and humidity controllers. However, because they are universal controllers, their working methods and control methods are basically the same. In order to meet the use methods of manufacturers of constant temperature and humidity test chambers, some advantages of the controller's own hardware, such as data recording, are sacrificed.,USBExport, remote control and other functions (general controller manufacturers will charge additional fees to earn additional profits). This allows manufacturers of constant temperature and humidity test chambers without technical capabilities to easily assemble a test chamber.

2.Finished product controller labeling method,Publicize that the company has an independent research and development capability control system to increase the company's technological soft power..These manufacturers are the worst.,Often take inferior controllers to carry out price sales.

3.Independent development of controller constant temperature and humidity manufacturers, such as: Espex,Qing Sheng,Hongjin, etc., has its own independent development of the controller of the constant temperature and humidity test chamber manufacturers have distinct characteristics.,Remove functions that are useless to the user,Free development of common functions for users, Such:USBExport test data,PCFeatures such as online functions. And at any time according to the characteristics of customer requirements, to customers to customize the control system to meet customer conditions. Really close to users, instead of assembling a test box with a bunch of accessories bought in the electronic market and giving it to customers..
