Setting up a control loop in PID controllers is an intricate process that has to be executed with the utmost precision. This article walks through the process.
According to the best available research, improvements in the user interface in a piece of technology can yield improved efficiency of up to 700%, factoring in ease of use, ease of training and reduction in errors committed. Modern controllers such as PM PLUS are designed with this in mind, and can provide a distinct competitive advantage when deployed into both new and existing processes.
A temperature control loop is one of the most common examples of a control loop. Control loops work to maintain the temperatures in our homes and offices. They are used for a range of immersion and industrial heating systems as well. Click the headline to continue reading.
Thermocouples and RTDs can become damaged and incorrectly read the current and temperature of your heating products. If you have unusual temperature fluctuations or temperature differences between multiple heater bundles, a replaced or repaired sensor can restore your heating process to optimal performance.
Typical customer specifications for a direct electric heat exchanger (DEHE) in forced convection gas applications aim for efficiency and safety given the technology principles that have been in place for the last two decades. While the older specifications are conservative and safe, the design may be sub-optimal.
Modern process controllers not only help suppliers in the aerospace industry to comply more easily with Nadcap requirements and speed up audits—they also help guarantee quality. A great example of such a controller is Watlow’s F4T, which incorporates batch mode functionality and hassle-free, pre-formatted reports.
Electric process heaters that interface with flammable materials in explosive environments need to be properly evaluated to protect the equipment against catastrophic failures. A temperature class requirement will be provided by the user based on the explosive gases that may be present in the installation area. Click to read.
One of the most common failures in electric process heaters used in various industrial applications involves electrical terminations and not the heating elements. Engineers at Watlow® believe designers across the industry are underestimating the temperature profile from the heater flange to terminal enclosure in these thermal systems.
By using HELIMX™ circulation heaters in its BPA processing, a manufacturer was able to widen its maintenance window by two to three times what it traditionally has been, saving both time and money. Read more
Companies in liquified natural gas (LNG) and other industries have been taking bold steps to reduce their carbon footprint. The overall strategy of these companies is to tackle carbon emissions not only through alternative energy investment and increased efficiency, but also through converting key industrial processes (like process heating) to electric (rather than fuel-fired). This paper explores pressures to electrify process heating, as well as the role that electric heat exchangers are playing, particularly in light of innovations in the design of these heaters.
Most industrial electrical heating problems can be readily solved by determining the heat required to do the job. Learn how to convert heat requirements to electrical power to select the best heater for your application.
Choosing an industrial electric heater is a complex process including everything from how hot it will operate to the safety factors and life cycle of the unit. The replacement costs also need to be taken into consideration. Here we highlight some of the main areas that should affect your heater selection.
The power controller is a discrete output device that regulates your system with guidance from the temperature controller. There are three common power controllers: electromechanical relays, solid-state relays and silicon-controlled rectifiers (SCRs). Click to continue reading.
