RTD's

RTDs are constructed using thin film technology. Thin film elements
are made by depositing platinum or nickel on a substrate and
trimming to the desired resistance. Ceramic elements are employed
for cryogenic applications and used with a mineral insulated
sheath for high vibration applications. Smart RTDs are available
in platinum, nickel and copper and with several different resistance
to temperature coefficient curves.
