Think Safety All thermal systems pose inherent hazards if applied incorrectly. Improper application and failure to adhere to recognized national, state and local electrical codes as well as agency standards can result in injury to personnel or damage to plant and process. Users are responsible for determining controller or sensor-to-application compatibility. Care should always be exercised in controller or sensor selection, installation and use. Responsibility for sensor and controller installation and wiring lie with the customer. Each sensor, power and temperature controller is packaged...

Think Safety Designing Safe Thermal Systems Designing Intrinsically Safe Circuits Most heated thermal systems include: • A heat source, either fuel fired or electrical resistance • A temperature controller • A temperature sensor The sensor produces a signal value based on the temperature to which it is exposed. The temperature controller interprets the signal into a value that is either above, below or at a then predetermined set point. The controller will then create an output signal to command a device to turn the heat source on or off. As with any heated thermal system, failure in the...
