High Temp Power indicator (>110C)

(1/3) > >>

Otwin38BOH:
Hi,
Has anyone had experience sourcing a power-on indicator that will function in an environment that will be 110-120C?
I'm looking for something that would be small & panel mount. LEDs are specifified to 85-100C. Incandescnt bulbs may be an option, but I can't find any temp specs for those that indicate whether they function on that temp range. Obviously oven bulbs function at 300C+, but are much too large for an indicator, but gives hope an incandescent bulb may work.

Any feedback on this would be appreciated.

Thanks,
Kevin

Neon lamp?

SeanB:
Neon or incandescent lamp, temperature more limited by the holder that you use for them, so you are kind of stuck on using a metal and glass lamp holder for them.  No plastic on them, unless you have bakelite, which even then will suffer from degadation with time, thus you need ones with ceramic insulators.  normally this is a neon lamp, with associated resistor, which can easily withstand the temperature, though the connections between the lamp, resistor and the wires are going to need to be crimped uninsulated connections, with glass fibre sleeving over them, and high temperature glass fibre sleeved wire to apply power to them.

Otwin38BOH:
Thanks for the replies. I'll look into a neon option, though it seems to be focused on 120V power, where I have 28V DC.
I imagine we'll use teflon wires and crimp as much as possible.

LEDs work fine at 150C+
Don't worry about specifications :P
Keep power dissipation as low as practicably possible.

For 120C, solder is fine, don't need to use crimps unless you specifically want to.
