A Fixed Threshold Detector triggers an alarm when a specific temp threshold is reached or exceeded. This type of detector is generally less sensitive to rapid temperature fluctuations, making it more suitable for areas like large, industrial kitchens where ovens or other heat-producing equipment are frequently in use.
In a car equipped with air conditioning, outside air, or cabin air if the recirculation flap has been set to close the external air passages, is first forced, often after being filtered by a cabin air filter, through the air conditioner's evaporator coil. This can be thought of as a heater core filled with very cold liquid that is undergoing a ...
Standard North American installation of a combination hot box / dragging equipment detector A defect detector is a device used on railroads to detect axle and signal problems in passing trains . The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur.
When the plastic heats up, it expands, forcing the carbon grains apart, and causing the resistance of the device to rise, which then causes increased heating and rapid resistance increase. Like the BaTiO 3 thermistor, this device has a highly nonlinear resistance/temperature response useful for thermal or circuit control, not for temperature ...
Weather Eye heater a 1967 AMC Marlin The Weather Eye was a trade name for a Nash Motors -designed fresh-air system for automobile passenger compartment heating, cooling, and ventilating. [ 1 ] The Nash "All-Weather Eye" was the first automobile air conditioning system for the mass market . [ 2 ]
The hot film MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal. This sensor uses a hot film-grid instead of a hot wire. [3] It is commonly found in late 1980s and early 1990s fuel-injected vehicles. The output frequency is directly proportional to the air mass entering the engine.

A parked car plugged in to an electrical outlet to power the block heater. Block heaters are frequently used in regions with cold winters such as the northern United States, Canada, Russia and Scandinavia. In some countries where block heaters are commonly used, carparks are sometimes fitted with electrical outlets for powering the block heaters.
