Overview

Improving temperature-regulation accuracy and efficiency in industrial heating processes can reduce operating costs and increase process repeatability. This presentation, intended for process and design engineers, focuses on the critical roles of electric-heat temperature measurement and power control. It covers key considerations in device selection, installation and set-up techniques, and methods of operation to control your temperature-critical process with the highest accuracy and efficiency.

Should you use contactors, solid-state relays, or SCR power controllers? We'll review various power control options available on the market, considering key advantages, typical network communications capability, and cost-saving features.

We'll discuss interface software tools and features to manage set up and monitor operation-and can even allow you to tap into data for greater process insights and control. We'll also look at operating modes, including zero-cross (full-cycle) mode and phase-angle mode, as well as SCR power controller output regulation methods for voltage, current, and power output regulation. Regardless of your application or specific process conditions, there are measures you can take to more accurately and efficiently control your industrial thermal process and lower your cost of operation and total cost of ownership.

Key Take-Aways

  • Understand the primary parts of a typical temperature control loop and the power control loop for electric heating
