Hello all, I'm prob. going to be ordering a complete gauge package for my rig, and was wondering if anybody makes a Pyro warning light set up?? I have auto meter gauges and warning lights in my cars, and the warning lights will come on at a certain temp to let you know that your getting close to dangerous temps.

I was wondering if anybody made something like this for our trucks, would be nice to have like a red LED or something come on at a certain temp to let you know your EGT's are getting up there. I know alot of people will say, just watch the gauge, and this is why I have them in my cars, so you dont have to keep staring at the gauge, you set the warning a few degrees before max, and the light will come on to let you know your getting up there.

Thanks for any info!!

 

I guess no one has heard or seen anything like this for our trucks??

 

Not that I'm aware of, but I'm sure you could get a digital one to go off at a set temp.

 

the dakota digital and spa have upper limit alarm settings... both are digital.

i don't think anyone makes an analog one, but i suppose you could make one with a relay, transistor, zener diode and a thermalcouple... it would need to be a relay that triggers off a low voltage/amperage signal, and adjustable, so you could calibrate the probe output at a set temprature to trigger the relay to set off a light or alarm..

[edited to add transistor & diode]

i guess you would need to find the right zener diode to crack at the voltage that is outputted by the thermal couple at say ~1250f.. feed that power to the transistor and use it to trigger the relay [could be a standard automotve relay]

temp goes above that point and the alarm sounds, below that the voltage gets blocked, the relay drops out and alarm stops
