A smoke detector contains two radiation transmitters and two radiation receivers. Each of the radiation transmitters emits in a different spectral region, for instance, one emits above and the other one below 600 nm. One part of the radiation of both radiation transmitters is conducted via a ...

Smoke Detector Based on the principle of the extinction of radiation, in which the impairment of radiation because of the smoke is detected in the measuring Section, and an evaluation Circuit through a Signal alarm to reach a Predetermined impairment in Radiation.It consists of two emitting ...
In a line extinction detector using a pulse-operated radiation source, a radiation receiver is connected to an input amplifier of an evaluation circuit. The output pulses generated by the input amplifier are compared to a reference voltage. Circuit elements having a time constant above one minute ...
