Ion smoke sensor probe
1. Ion chamber characteristics:
(1) Single-source dual-chamber structure designed by computer simulation;
(2) In the approximate standard atmospheric pressure, relative humidity 95% and -10 ° C - 40 ° C clean air, the working power supply voltage is 9V, the collector balance potential change value is maintained at 5.3-6.5V; can also adapt to different working power supply voltage , its parameters vary with voltage;
(3) Radiation safety: single source, low activity, safety performance meets grading standards:
(GB4075≈ISO2919) C64646;
(4) Using stainless steel and high-performance insulating materials, the leakage current is small; the surface of the ionization source is high-resistance metal palladium;
(5) The bracket and the empty slot of the base of the ion chamber are suitable for being mounted on the upper part of the IC component, and the pin of the IC component 15 is close to the collecting electrode, and is easy to solder, which can effectively shield the RF interference;
(6) All solder joints are pre-coated with solder for easy soldering;
(7) Product consistency is good.
