This RTD sensor incorporates
a copper tip which provides an
improved heat transfer path
between the sensing element and
the process conditions allowing
for reduced response times and
better temperature tracking. This
becomes especially important in
applications where the sensor has
little exposure to the item being
measured such as in thermowells
and bearing temperatures.
The M12 connector provides a
secure connection for all types of
applications. The probe can be
ordered straight or with mounting
threads of
probe is also offered in a metric
millimeter size and M8x1 and
M10x1 mounting threads.
