PID Controllers

MRK Engineers has introduced the latest PID controllers. These microprocessor based PID controllers use latest two fuzzy PID control process. Unique features of the PID controller include auto tuning, two outputs, remote set point input, transmitter output and universal signal input (i.e., thermocouples, RTD, mV or mA inputs). Sensor break protection is also provided. Output can be selected from relay, SSR or 4-20 mA. Non volatile memory in the instrument stores all the programmed parameters. The instruments have self-diagnostic features and offer three point alarm. These can also have retransmission output and provide time temperature profile control. Two patterns of eight segments each can be programmed in the instruments. The ramp and soak are provided with standard model controller without any additional charges. These PID controllers can operate on wide power supply, i.e., 85 V AC to 265 V AC. These instruments are housed in strong ABS plastic enclosures, and are available in sizes 48 x 48 mm or 72 x 72 mm or 48 x 96 or 96 x 48 mm or (96 x 96 mm) and priced very low. These low cost high quality instruments are ideally suitable for automation industries, plastic machines, furnaces, temperature baths, process control, heat treatment unit, oven, blood bank refrigeration, and most of the process industries where accurate temperature control is more important.
