Advanced Ionization Technology:</strong> The ion chamber smoke sensor is equipped with a high-performance, low-activity Am-241 ionization chamber. It features an ionization source activity of 0.5uCi (18KBq) to 0.8uCi±10% (30KBq±10%), ensuring reliable smoke detection.<br /> <strong>2. Radiation Safety Assurance:</strong> This ionization smoke detector adheres to safety standards (GB4075, IS02919.C64444), with a radiation dose rate of 0.03mGy at 25cm from the ion chamber smoke sensor, significantly lower than the 1mGy public dose standard.<br /> <strong>3. Sensitive Smoke Detection: </strong>The smoke sensor detector adjusts its collector electrode potential as smoke concentration changes, with light attenuation rates of 1% at 0.6V and 4% at 2.2V, providing precise and responsive smoke detection.<br /> <strong>4. Stable Operating Conditions:</strong> Designed for optimal performance at 9V VDD supply voltage and ambient temperatures around 20°C, the smoke sensor functions effectively under standard atmospheric pressure and clean air conditions.<br /> <strong>5. Reliable Electrical Characteristics: </strong>The ion chamber smoking sensor features a collector equilibrium potential of 5.3~6.5V, with a maximum insulator leakage current of 0.5Pa and a capacitance of 6.0pF, ensuring consistent and accurate operation.<br /> <div> <br /> </div> <br /><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China</span><br /> <span>Product size: about 35.00x35.00x20.00mm<br /> Product size: 1.38x1.38x0.79inch<br /> Material: Metal<br /> </span>1.
