Refrigerant gas leak detector
Added 2023-07-03 15:59:43 +0000 UTCThis is an older style detector used to sniff out leaks in refrigeration systems.
There are a few different technologies used for leak detection, including ionisation, ultrasonic hiss and the mysterious heated diode detector that breaks gases down with heat for their test.
While working with Hussmann in the UK I could actually detect leaks by nose, not because of the smell of the refrigerant itself, but the fine haze of oil it emitted. It had a faint coconut type of smell.

It's worth noting that there are other leak detection methods available, such as electronic leak detectors, dye-based detection, and infrared imaging, each with its own specific uses and benefits. The choice of the leak detection method depends on the specific requirements, the type of refrigerant used, the size of the system, and the location of potential leaks.

2023-07-04 04:57:56 +0000 UTCI do enjoy when I see exploration of clever use use of analogue circuit coupled with elegant digital circuitry as opposed to just slapping a microcontroller onto everything. I do agree, a Geiger type effect would have been much better, and seems like it would have been easily executable with the available board real estate. Perhaps changing the 556 to something like a 40106 that could have had different stages being loaded up by the 324 being used in comparator mode.

2023-07-03 17:05:29 +0000 UTCIt would be interesting if you could point the detector at an alpha source to see if it is detected. The device is, after all, a geiger counter that uses air at atmospheric pressure as the ioniseable (is that a word?) gas.
