A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element.
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 ...
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 ...
Work Completed: Fuel injectors replaced, timing chain and plastic chain guides replaced, HVAC air vent vacuum actuators replaced, heater box repaired, cracked dashboard reupholstered in German vinyl, leather seats recovered, center console veneer panels replaced, front suspension refurbished with new shocks, lowered springs and new anti-roll ...
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

Commonly used in distributors for ignition timing (and in some types of crank- and camshaft-position sensors for injection pulse timing, speed sensing, etc.) the Hall Effect sensor is used as a direct replacement for the mechanical breaker points used in earlier automotive applications. Its use as an ignition timing device in various ...
