Temperature and process controllers

Controllers are the part of any control system that add value by improving the repeatability of the process, the quality of the product and in doing so reduces production costs. When choosing a controller there are several factors that you will need to take into consideration.

Where you have a process that requires fast response and you would like to be able to add some digital input and output switching, in addition to standard PID, or Fuzzy logic control. We would recommend the PXG family of controllers. These provide a competitive solution to mid range applications and are available with custom front panels for OEM customers.

Where applications are more demanding and require the processing of up to 3 inputs to be used in the control rational the PXH family of controllers would be our recommendation. This family provides fast processing times which are suitable for the control of pressure and flow applications.

Physical Size
The size of the physical size of the controller may be important to you if you are replacing an existing controller and you would like to avoid cutting or blanking holes in your existing control panel. It may also be an important consideration for OEM customers where a short format controller reduces the overall depth of the control panel which leads to lower build costs. Lastly the size of the controller may make it easier to read the display from a distance. Which ever of the above is important to you, Fuji Electric have a model to suit.

The industry tends to use DIN terminology to describe the size of the front face of panel mounted controllers. The following table provides an explanation of this terminology with dimensions shown in mm. For completeness we have also shown the Fuji Electric models that satisfy the DIN sizes.

Size	Width x Height	Panel Cut out size (W x H)	Fuji Electric Models	Length Behind the panel (mm)
1/32 DIN	48mm x 15mm	45mm x 22.2mm	PXR3	97mm
1/64 DIN	48mm x48mm	45mm x 45mm	PXR4, PXG4	80mm
1/8 DIN	48mm x 96mm	45mm x 92mm	PXR5, PXG5	78mm
	72mm x 72mm	69mm x 69mm	PXR7	78mm
1/4 DIN	96mm x 96mm	92mm x 92mm	PXR9, PXG9, PXH9	78mm
	96mm x 192mm	92mm x 190mm	CCM

Physical size may also be important if you require a "behind the panel" controller that is mounted on a DIN rail. In this case Fuji Electric offer the PUM range of controllers.

Price
Fuji Electric are one of the largest manufacturers of electronic controllers in the world. Our pricing is driven by ability to control the whole manufacturing process. This includes the manufacture of our own silicon chips and microprocessors, A claim that no other instrumentation manufacturer is able to make. With millions of controllers being manufactured each year, economy of scale enables us to offer quality/cost breakpoints that can only be offered from a high volume manufacturer of world leading quality and reliability.

If you are an OEM user of temperature controllers, or you just want to reduce your purchasing costs, send us your application details and volume requirements to receive our best price.
