Programmable Ramp / Soak PID Temperature Controllers


Libratherm offers Microprocessor based multiple Ramp / Soak programmable PID Temperature Controller Models PRC-300, PRC-309, PRC-309-2 and PRC-310. These are designed to improve reliability, accuracy and control for all processing applications. It features Ramp and Soak functions (the capability to control the temperature and its rate of change over a predetermined time span). One to ten different patterns each of total sixteen (ramp/soak) steps can be programmed into the memory with the user-friendly membrane keyboard. Separate displays are provided to monitor simultaneously the Process temperature, Set temperature and the Program number. It can also be used as single set point control when the profile control is not desired. Inputs can be Thermocouple, IR Thermocouple, RTD Temperature Sensors, Voltage, Current Signals and etc.

It offers both switching outputs in the form of SSR or relay to drive external load contractor and continuous control outputs in the form of (4-20)mA or (0-5)volt etc., which can be used to control heater power through Thyristor power pack (for electrical heating system) or to control the position of a modulating motor valve (for oil or gas fired heating systems). The analogue outputs can be directly connected to Libratherm make single phase / three phase SCR phase angle fired power controller which is ideally suitable for both resistive and inductive heating load. Additional 2 relays are also provided for time or temperature dependent event outputs as per the system requirement. The programmed profile and other parameters are retained in the non-volatile memory in the event of power failure. To monitor the on temperature profile of the heating system, serial communication port on either RS232 or RS 485 interface can also be optionally provided, the same can be connected to the computer. Libratherm provides the window based software to view the on line behaviour of the heating system in both graphical and tabular format.
