WebConsumers Union, the nonprofit publisher of Consumer Reports, recommends you install smoke alarms with two different types of sensors: Ionization sensors ($10 and up) are better at detecting fast, flaming fires. Photoelectric sensors ($15 and up) are better at detecting smoldering fires. Your best bet is to buy dual-sensor alarms ($25 and up ... WebThe time required for the detector to respond to an optical input. The response time is related to the bandwidth of the detector by BW = 0.35/tr where tris the rise time of the device. The rise time is the time it takes for the detector to rise to a value equal to 63.2% of its final steady-state reading. Response time Junction capcacitance 1/RC

WebA calorimeter measures the energy a particle loses as it passes through. It is usually designed to stop entirely or “absorb” most of the particles coming from a collision, forcing them to deposit all of their energy within the detector, thus measuring their full energy. Calorimeters have to perform two different tasks at the same time ...
