pyrometer question

I have the 0-1800F pyrometer, part number R3607R. Does this gauge use the same signal amplifier as the 0-1500F gauge, part number R3607TR?

I am guessing they do, but I do not have the amplifiers side by side to do a comparison.

Thanks.

Sorry, I was out of the office and missed this thread until now.

The 0-1800 and 0-1500 pyrometers do NOT use the same amplifier boxes. They look very similar from the outside, but they are different internally.

If you are just swapping parts to determine which part is bad, the amplifier boxes will work with the different range gauge, but they would not be accurate.
