|More About Temperature Controllers|
Fuzzy Logic Controllers
Temp, Inc. manufactures a variety of temperature controllers for use in industrial control of your process. The temperature controllers are available to accept sensor inputs from Thermocouples, RTD, Thermistors, Millivolt output of radiation pryometers, and d.c. voltage and current output of process transmitters/transducers. Depending on the process requirements, temperature controllers are available as ON/OFF time proportioning and true proportional PID controllers.
The SMART 2 and 3 Temperature Controllers
also have available
other features such as
auto-tune, fuzzy logic, serial communications, auto/manual control mode; Deg. C/Deg F selection, ramp/soak programming, and programmable alarm.
A variety of physical packages are also available such as 1/16 DIN and 1/4 DIN enclosures, DIN rail mounting, plastic snap track mounting, P.C. board w/remote control panel, P.C. boards for plug-in P.C. expansion slot, multiple plug-in units w/rack mounting enclosures and custom packaging to customer requirements. The controllers can be furnished with customer name/logo at no extra cost.
There are 3 basic types of Temperature Controllers: ON/OFF, Time Proportioning (Variable ON/OFF ratio) and PID (Proportional plus integral plus derivative.) Depending on the response characteristics of the system to be controlled, one of the 3 types of control is selected. When in doubt as to your specific needs, the Temp, Inc. SMART-2 and SMART-3 Temperature controllers make an ideal selection. These controllers also allow the user to either set the control parameters manually or he can opt to use the auto-tune feature for either the time proportioning or PID modes. The auto-tune at the entering of a yes command will select the best possible control parameter settings by internal analysis of the system response. The control function for auto-tune can be selected for either (1) Fuzzy Logic control or (2) Standard PID algorithm control function.
The ON/OFF mode for control is not used too often, as the superior time proportioning mode can be used for either operation of a relay type output or a solid state relay control. The ON/OFF control is used when overtemperature (Hi Limit) control is desired. ON/OFF control is usually used in systems that cannot tolerate the power being turned ON and OFF frequently as with a time proportioning type of control. The PID true proportioning control in conjunction with a proportional SCR Power Controller is used in the more sophisticated systems, providing the most accurate control and minimum variation of power to the heater load.
