Single Loop Temp & Process Controllers

Single loop controllers are cost effective and easy to use devices used in temperature and other processes to control one specific variable. From basic devices with core functions, to those with advanced features, a range of single loop controllers are available to ensure precise control for demanding applications. Typically, single loop controllers are front-of-panel products. Many of our controllers have a high visibility display for increased clarity that enables vital process information and alarm messages to be viewed at a glance. These features allow the single loop controller to control process variables in a wide variety of applications that include industrial and lab ovens, sealers, kilns, food processing, extruder barrel heating, and heat presses, to name a few.

West Control Solutions offers an expansive line of products from its leading brands, CAL, Partlow, PMA and West. The range includes digital controllers available in 1/32, 1/16, 1/8 and 14 DIN sizes and offers products with varying degrees of functionality from basic to sophisticated.

The chart below presents a selection of our most popular single loop temperature and process controllers.
