Procon technologies supplies fuzzy-logic auto-tune pid temperature controllers [pxz series]. These pid temperature controller is manufactured by fuji electric co ltd, japan. Various technical features of these pid temperature controller include: temperature controllers 3 or 8 button operation, multiple input signal [tc/rtd/mv/ma], pv/sv independent or selective display, choice of control outputs [relay/ssr/voltage/current], single or dual alarm outputs with a choice of 16 different alarm settings, advanced security options, versatile programming and fuzzy logic intelligence. Following are some the additional features of these pid temperature controller: nema 4x faceplate, heater burnout alarm, 8-segment ramp/soak programming, 24 v ac/dc power supply, serial communications are also available. All the z-series controllers use fuji`s patented fuzzy logic algorithm with pid auto-tune. These temperature controllers learn the process using pid parameters as a starting point for all decisions made by them. The process is allowed by the intelligence to reach its setpoint in the shortest time possible while virtually eliminating overshoot. Following are some of the electrical features of these temperature controller :the z-series controllers operate on 85 to 265 v ac and are available in 48 mm x 24 mm, 48 m square, 72 m square, 48 mm x 96 mm, and 96 mm square sizes. The pid temperature controllers conform to standards set by ul, c-ul, ce, and nema 4x/ip66.
