The Fuji PXR4 temperature controller is an advanced, 1/16 DIN temperature and process controller. Designed for a wide range of applications, the PXR4 not only includes auto-tuning and fuzzy control, but also features self-tuning - an innovation in the control field. Self-tuning automatically re-tunes the controller under certain conditions, without the need to revert to auto-tuning.
The PXR4 accepts process and temperature inputs and offers a choice of three kinds of outputs; relay, SSR driver, or 4-20mA. The controller's standard 8-segment ramp/soak feature has been expanded to include two patterns that can be linked to create a 16-step profile.
One of the most impressive features of the PXR4 is the large LED display. The faceplate, designed for NEMA 4X (IP66 equivalent) is watertight and corrosion-resistant. The easy-to-use 3-button keypad makes programming quick and easy. The socket terminal on the back makes this unit conveniently plug and play.

This product can be used in the following applications:
The Background: Our customer is an OEM manufacturer of commercial dryers. They require a way to maintain the operating temperature of their dryers.
The Problem: As an OEM application, it is important that the solution be simple, cost effective and provide absolute reliability over the expected life of the dryer.
The Solution: The customer opted to use a Fuji Electric PXR4 temperature controller with a circuit added enabling it to work with a fixed infrared thermometer with a K-type output. The IR sensor is mounted on the internal shaft of the Drum to measure the temperature and the output of the controller maintains the dryer temperature.
