Flame detection using 24V DC power supply 1

[bren37]

I want to monitor the flame of a propane gas burner which is mounted on the back of a truck. The normal method would be a manual valve worked of a themocouple but I would like a devise that would work instantaniously in the case of a flame failure. We have 2 x 12V Batteries on the truck. My question is:
Is there a device on the market that will suit this application?
Preferably useing a UV cell rather than ionisation flame rod.

At our site we have numerous UV flame detectors and all run on 110V/220V AC. The older non-checking models didn't draw very much current. The newer self checking models draw considerable more current. Sorry I don't have access to the exact numbers.
UV detectors are a lot more expensive. Repairs are also quite expensive.


We also have over 30 small gas burners, 600,000 - 900,000 BTUs' that use flame ionization detectors that give absolutely no trouble. I just checked and the spare parts have been in stores for 20 years, with no withdrawals.

Unless this is a very critical operation I believe I would stick with the ionization detectors, most of which are available at the local heating and cooling supply co.

try looking at reuter-stokes uv flame detectors, work on 24vdc supply and return a 4-20mA signal.

Contact Fossil Power Systems. Thier web site is:

Part of their ignitor control package is the "SunSpot". it uses the flame to complete the DC circuit.

When there is fire, a set of contacts will make (or break).

I donna am I late for your question or not, but there is a company I work with and they have a lot of options all work on 24 VDC, UV, IR or UVIR flame detectors
check: De-tronics

Thanks
