Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As a kind of embodiment of the utility model, consult Fig. 1, the utility model comprises Muffle furnace; Be provided with temperature measurement module in the Muffle furnace, also comprise host computer, PID controller, voltage regulating module, display module and modular converter, the output signal of PID controller inserts voltage regulating module; As the input control of voltage regulating module, voltage regulating module is electrically connected with Muffle furnace, and temperature measurement module is electrically connected with the PID controller; Display module links to each other with the PID controller, and the PID controller links to each other with host computer through modular converter.The PID controller is 64 sections cyclelogs of XMT-908CP, and its output signal is 0 ~ 5V.Temperature measurement module is a thermocouple.Voltage regulating module is the single phase ac regulation module, and its electric current is 40A, and input signal is 0 ~ 5V.The voltage regulating module controllable silicon.Modular converter is a serial converter.
Thermocouple is sent the temperature signal (z) of Muffle furnace into controller (XTM-908CP); Compare with set-point and to obtain deviation (e=x-z); By exporting 0 ~ 5V signal voltage after the PID computing, voltage regulating module is realized temperature control according to the voltage of the size adjustment Muffle furnace of voltage thereby regulate its power to controller according to deviation (e) size; In the temperature programmed control test, the reaction time of Muffle furnace shortens; The heating power of Muffle furnace is relevant with rate of temperature change, and like quick heating, heating power is big.In the section that heats up, program line and intensification line parallel, at each constant temperature zone, program line and intensification line overlap basically, and worst error is 2.1 ℃, and corresponding error is 0.53%, and precision is higher.Modular converter can be the USB-RS485 serial converter or for the USB-RS232 serial converter, can carry out the monitoring of computer through the instrument upper computer software.
Although having combined current taking as is that a most practical and preferred embodiment has been described the utility model; But be to be understood that; The utility model is not limited to the disclosed embodiments, and is intended to contain spirit and interior multiple modification and the equivalent arrangements of scope that is included in accompanying claims on the contrary.
