Multi Loop Controllers


Limit Controllers

Multi-loop temperature controllers manage several zones simultaneously to stabilize the temperature of environments such as ovens, packaging, and heat treatment. Generally, behind panel, multi- loop controllers support various fieldbus options allowing for easy integration with other devices within the machine or a wider plant network. Multi – loop systems can be programmed to allow the zones to be independent or to work in conjunction with one another, depending on the needs of the application. Benefits of the multi – loop temperature controller includes reduced installation costs, improved integration and minimal machine downtime.

Multi Loop controllers are generally mounted behind the panel, as opposed to single loop controllers which are often front panel mounted. A proprietary software for PC’s is most often used to program and download settings to the multi-loop temperature controller.

West Control Solutions offers a range of controllers from its leading product brands, CAL, Partlow, PMA and West. These meet a variety of differing control loop requirements as well as providing different degrees of functionality.
