West Instruments | Temperature Control

West (formerly West Instruments) was established in 1946 and was one of the first controller manufacturing companies to market microprocessor based temperature controllers. It was at the forefront in the development of self-tuning algorithms.

More recently the West Instruments product brand has been rebranded simply as West and together with CAL, Partlow and PMA it has formed West Control Solutions. 

Based in Brighton, UK, West continues its research & development and manufacturing traditions and is the worldwide centre of excellence for the development and manufacture of temperature and process controllers for the entire group.

West specializes in the following products for a range of industrial and scientific industries such as heat treatment, ovens and furnaces, plastics and extrusion, food and beverage applications:

  • Single Loop Controllers
  • Limit Controllers
  • Valve Motor Drive (VMD) Controllers
  • Multi Loop Controllers
  • Temperature and Process Profilers
  • Process Digital Indicators
