Yeah, those critters have been around for awhile. I bought
one a number of years ago to evaluate. That version used
a forward biased diode as a temperature sensor. It was pretty
good for non-industrial/aviation use. There are some new,
more sensitive, VERY linear temperature sensors that could
be applied to products like this. In fact, the would push
suitability of the device's operating range up high enough
to use for oil temperature measurement too.
Next time a put in an order to MPJA, I'll pick one up
and check it out.
