CAL Controls is a global industry leader in temperature and process control products. With a long track record of success, it’s no wonder that CAL is one of our top brands of limit and temperature controls. In this article, we’ve compiled ten interesting facts about CAL limit and temperature controls to help you learn more about these excellent industrial electrical solutions.

1. CAL limit and temperature controls are designed by technology and innovation leader, CAL Controls. CAL Controls was the first to develop the CAL 1/16 DIN analog and digital controller and the CAL 1/32 DIN digital controller, establishing themselves as industry leaders in the life sciences and laboratory market.
2. CAL Controls was established in 1963 in Hertfordshire, United Kingdom. Since its inception nearly 60 years ago, CAL Controls has joined West, Partlow, and PMA brands as part of West Control Solutions, a global leader in rugged and reliable temperature limiters and controllers.
