Ceramic Wire-Wound
Platinum RTD Elements
Class A (IEC751), Alpha = 0.00385
-200 to 600°C
(-330 to 1110°F
)
The “KN” Series RTDs are suitable for applications requiring extremely high temperature stability and high temperature shock resistance.
Deviation from the IEC751 characteristic curve is minimal over the entire temperature range. The small diameter tolerances of the sensor body
allow easy installation in protective tubes. Applications are found in chemical and power generation plants and with analytical equipment.

Glass Wire-Wound
Pt RTD Elements
Glass wire-wound platinum RTD elements are made
by winding a platinum wire onto a glass core and
then fusing the exterior with glass. They are suitable
for low or very high temperatures and are tolerant of
thermal shocks. They offer good vibration resistance
(depending on mounting method).
