PID Controllers

32 products

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.

Frequently Asked Questions

A PID controller is an intelligent device that uses a mathematical algorithm to maintain a process variable (like temperature or pressure) at a specific setpoint; HK Calibrations provides these to eliminate the "overshoot" and oscillations common with simple on/off controllers, ensuring smoother industrial operations.

Most modern controllers are "universal," meaning they can be configured for various inputs; HK Calibrations specialists can help you select between thermocouples (K, J, T types), RTDs (Pt100), or linear DC signals (4-20mA) depending on your required temperature range and accuracy.

The Auto-Tune feature allows the controller to automatically calculate the optimal Proportional, Integral, and Derivative values for your specific system; HK Calibrations recommends using this during initial setup to save hours of manual trial-and-error tuning.

Yes, many of our dual-output models are designed to manage complex systems that require both heating elements and cooling fans or valves, providing the precise thermal control necessary for Australian laboratory and chemical processing applications.

We offer various output options, including Relay (for slow switching), SSR (Solid State Relay) drive for high-speed pulsing, and 4-20mA Analog outputs for modulating valves, ensuring HK Calibrations has a solution for every type of actuator.

Even the most advanced controller is only as accurate as its input reading; HK Calibrations provides professional calibration services to verify that the controller correctly interprets the sensor signal, ensuring your critical processes remain compliant with Australian safety and quality standards.
