Sensors

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, miniatur-

ized and surface mount hous-

ings (including printed circuit

board termination). Potential

applications include motor

overload and semiconductor

protection, electronic assem-

bly 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 tempera-

ture. The change can occur in

the surrounding temperature or

by passing a current through

the thermistor to self-heat.
