Insert these thin, laminated RTDs in winding slots to detect
high temperatures before insulation damage occurs. RTD
temperature sensors continuously monitor conditions and
provide the long term trend data that is necessary for
making adjustments before unexpected alarms occur. These
models are designed for use in hazardous areas, where there
may be a presence of flammable gas under normal operating
conditions. Strict construction guidelines prevent arcing.
These RTDs are certified as “increased safety” and “intrinsic
safety” devices.

Wire-wound RTDs, embedded in stator slots, are the most
common method for measuring winding temperature in large
motors. The wire-wound element extends through most of the
body length and measures the average temperature of the
winding.
Thin-film RTDs are identical, except for the size of the sensing
element. Because the thin-film element is small, approximately
0.08" x 0.09" (2.0 mm x 2.3 mm), it senses the temperature in
only one small spot of the winding. Thin-film elements are best
suited for shorter length stator sensors.
