Photo Ionization Sensor are used as smoke detectors in industries due to high efficiency rating in detecting fast flaming fires, hence ensuring property and personnel safety in hazardous environments.

1. Ionization Smoke Detectors: - Pros: Detect fast-burning fires well, less false alarms. - Cons: Less effective for slow smoldering fires, contain small amounts of radioactive material.

They work differently in order to detect smoke. Ionization detectors use a very small amount of radioactive material inside of an ionization chamber with electrically charged plates. When smoke ...
