Temperature Sensors
HEL-700
Platinum RTDs
FEATURES
HEL-700 Thin Film Platinum RTDs (Re-
sistance Temperature Detectors) provide
excellent linearity, accuracy, stability and
interchangeability. Resistance changes
linearly with temperature. Laser trimming
provides ±0.3°C interchangeability at
25°C.
ɀ Linear resistance vs temperature
ɀ Accurate and Interchangeable
ɀ Excellent stability
ɀ Small for fast response
ɀ Wide temperature range
ɀ 3-packaging options
