Ever since one's first experience with a fever thermometer,
almost everyone has known what it means "to have a temperature". The
fever thermometer is still in abundant supply and still the second most frequent
test used (after a hand on the forehead) to indicate the presence of an infection
in the human body by noting an elevation in body temperature. Human
and animal body temperatures are so important to the well being of warm blooded
animals, that the nominal body temperature indicated by a fever thermometer or
similar device, is used as one of the vital signs routinely monitored as an indicator
of a state of a person's or animal's health. The temperature of
food plays a big role in assuring that certain products are well-enough cooked
to kill harmful organisms like bacteria. Similarly many foods, including cooked
food, become breeding grounds for other harmful organisms if unrefrigerated too
long or even if left in a refrigerated environment for too long a time. Certainly
in the cooking area it is quite straightforward to monitor the internal temperature
of meats and fish to assure that the proper minimum temperature has been attained
before it is considered safe. See the list of cooking temperatures for food
on our food temperature sensor page Certainly
there are other medical applications of temperature sensors, but this is perhaps
these more familiar uses are places to start into the vast area represented by
the medical field, food safety, veterinary medicine and related disciplines. Be
sure to come back and see the added areas soon.
