Process Control

Effective process control enhances the efficiency and performance of your operation. The heart of any sophisticated process is a controller that takes input from sensors and transmitters, measures process variables, and responds with output instructions to system components via relays and switches.

Davis Instruments offers a wide range of process components including process and temperature controllers, sensors and transmitters, relays and switches, signal conditioners, I/O modules, panel meters, HMI devices, and enclosures. Additionally, we provide the technical assistance you need when help is required to find the best solution for your application. Davis Instruments’ process control products are manufactured by leading industry brands such as Eurotherm, Red Lion, OPTO22, Action Instruments, Hoffman, and Digi-Sense.
