Temperature Sensors
Platinum RTDs
HEL-700
FEATURES
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
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.
TYPICAL APPLICATIONS
ɀ HVAC - room, duct and refrigerant
equipment
ɀ Electronic assemblies - thermal man-
agement, temperature compensation
ɀ Process control - temperature regu-
lation
1000ȉ, 375 alpha provides 10X greater
sensitivity and signal-to-noise. Both
1000ȉ and 100ȉ provide interchange-
abilities of ±0.6°C or better from -100°C to
100C, and ±3.0°C at 500°C.
