As the demand for energy increases, industrial systems are growing. Whether the need is petroleum, natural gas or other sources to generate electricity. As heaters grow in size and power controllers become larger, the thirst for more energy sources will only grow. Likewise, 10 years ago, Watlow’s most powerful power controller switched 500 amps. Today, the ASPYRE® DT SCR power controller can handle an incredible 2,100 amps.

Heater systems have several safety controls built in to protect workers, devices and materials. High-limit sensors, or safety sensors, are one of these types of devices. Such sensors prevent runaway situations in which a switch does not turn off a heater and it continues heating after reaching the desired temperature.These can be dangerous situations that lead to damaged materials and devices or a fire that could injure employees and damage property.

Temperature, process and power controllers have become highly sophisticated devices. Essential to thermal system operation and running a seamless process, controllers are communication tools capable of monitoring systems, switching power, logging and recording data and enforcing safety limits. But not all controllers are equal, and not all controllers speak the same language.
