Web14 dec. 2024 · The ionization chamber, also known as the ion chamber, is electrical device that detects various types of ionizing radiation. The voltage of detector is adjusted so that the conditions correspond to the ionization region. The voltage is not high enough to produce gas amplification (secondary ionization). Advantages of Ionization Chambers WebThe Series 65 Optical Smoke Detector uses light sensing technology to “see” smoke entering the chamber. The external detector moulding is identical to that of the ionisation detector, and has an indicator LED which is clear in quiescent state and produces a red light in alarm. Responds well to slow-burning, smouldering fires
