Discrete and Packaged RTD
Sensors:
Our platinum-based
RTDs are laser-trimmed for
accuracy and flexibility —
designed to offer stable and
fast linear outputs, accurate
and interchangeable,
plus plastic and ceramic,
miniaturized and surface
mount housings (including
printed circuit board
termination). Potential
applications include
motor overload and
semiconductor protection,
electronic assembly thermal
management and temperature
compensation, as well as
HVAC equipment.
Discrete Thermistors:
These sensors don’t amplify,
rectify, polarize or generate
a signal, but rather change
resistance with any change
in temperature. The change
can occur in the surrounding
temperature or by passing a
current through the thermistor
to self-heat.
