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.
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.
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 ...
Because the carbon dioxide used in car air conditioning is a recycled industrial waste product, it is an environmentally neutral solution. The Alliance claims that using a CO 2-based air conditioning system will reduce total car emissions by 10%, thereby sparing the planet 1% of total greenhouse gases. [citation needed]
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 ...

Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are largely used in ...
