PID Controllers

PID Controllers are used in a wide range of industrial, commercial, and laboratory applications and are used to control temperature, pressure, flow, and other process variables in an efficient manner. PID Controllers work by taking a measurement of a process variable and then sending a signal to a control device to adjust the process variable accordingly. This ensures that the process variable stays within a specified range. Omega Engineering’s selection of PID controllers offer full Autotune PID control, Fuzzy Logic, Ramp & Soak Profiles, Universal Inputs, High Accuracy, and other features. They also feature a wide range of sizes, from 1/32, 1/16, and 1/8 DIN, to 1/4 DIN, as well as RTD input and advanced features such as NFC/RFID technology.
