程序升温控制器通常由温度控制与程序控制等两部分组成.程序升温控制器的功能和特点主要体现在程序控制部分.虽然程序控制的方法多种多样,但本文介绍的利用步进电机控制的程序升温控制器,其控制部分较为简单、适用.它能按需要设计成各种升温速度的.我 Program temperature controller is usually composed of two parts of temperature control and program control, etc. The function and characteristic of program temperature controller are mainly reflected in the program control section.Although the program control methods vary, but this article describes the use of stepper motor control Program temperature controller, the control part of the more simple and applicable. It can be designed according to the needs of a variety of heating rate. I
