Ambient temperature sensors monitor air temperature around machines, engines, and equipment to prevent overheating and damage. They are used in manufacturing plants, automobiles, computer rooms, and can even monitor minimum temperatures.
Ambient temperature sensors are devices that measure the air temperature around or near a machine, engine, or other heat-generating equipment. These sensors are intended to prevent machines from overheating and potential damage. The equipment often has alarms set to alert an employee if the temperature exceeds the acceptable operating temperature. Some even automatically turn on air conditioning devices that lower the temperature around the car.
Manufacturing plants are one of the environments where ambient temperature sensors are frequently found. These facilities often have numerous machines that consume a lot of energy and emit a large amount of heat. This creates the danger of overheating, overloading of circuits and potential fire. Sensors are often recommended by the equipment manufacturer and are usually placed in close proximity to machinery so they can monitor ambient heat. In some locations and conditions, ambient temperature sensors and temperature control devices are required by governmental or environmental codes.
Many automobiles also contain ambient temperature sensors that monitor the heat generated by the engine. These sensors are preset with the optimal and maximum acceptable heat levels. If the engine generates heat above these levels, sensors will detect the condition and warn the driver, usually by activating a warning light on the dashboard. Ignoring these lights is not recommended, as operating the vehicle when there is too much heat can damage the engine and can also create a dangerous condition.
Rooms or facilities that contain large numbers of computers or a large amount of computing equipment, such as server rooms and computer labs, often also use ambient temperature sensors. Computers can stop working properly if the air in the room is too hot, and expensive key components can suffer damage. Sensors in computer rooms that are unmanned at night are often connected to air conditioning devices because excess heat can cause damage very quickly. As soon as the temperature rises above the acceptable level, the cooling equipment will automatically turn on and run until the temperature returns to acceptable levels.
In rare circumstances, ambient temperature sensors are also used to monitor minimum temperatures. This usually occurs when equipment that can potentially freeze or otherwise become inoperable when the temperature gets too cold is placed in an area exposed to cold temperatures. In these cases, the equipment is usually outside or protected by an uninsulated canopy.
