50-segment Programmable Temperature PID Controller for chamber muffle furnace

With functions of AI controller, 50 segment PID programmable controllers are applicable where the given value needs to

be controlled automatically following certain rules of time. The given increase/decrease slope can be set at will, so as to

get the capacity of slope heating/cooling or curve heating. With PID control arithmetic and without excessive and

insufficient adjustment, the reading in and out of all instrument parameters and function of heating power segment limit

can be realized on upper computers, together with functions including step control, manual/auto switch of no disturb as well as self turning. With 4-digit LED digital display, the measurement value and setting value as well as operation time

can be displayed at the same time. The control object can be controlled by programming in up to 50 segments of curve,

each of which adopts PID parameter setting control, making control more precise and reliable.

1.The setting scope for each segment of time is from 1 to 9999 minutes or from 1 to 9999 seconds.

2.With the jumping functions of the 1st to 50th segment of program, the memory and run of several different curves can be realized.

3.With RUN/HOLD function, the time counting starts and the given value changes following the pre-scheduled program

when the program runs and time counting stops and the given value is unchanged when the program holds.

4.The running program segment and remaining time to run this segment can be surveyed during running.

5.With 2-channel event output function, the event output generates under programming. The 2-channel alarm ON/OFF

action can be controlled during program running, so that various external equipments are easy to work in phase or in

chain.

6.With RDY and measurement activation functions, it can automatically resolve the uncertainty to the program caused by inconsistency between measurement value and setting value when starting running.
