Temperature Sensors
Platinum RTDs
HEL-700
FEATURES
1 Linear resistance vs temperature
1 Accurate and Interchangeable
1 Excellent stability
1 Small for fast response
1 Wide temperature range
1 3-packaging options
HEL-700 Thin Film Platinum RTDs (Resistance 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
1 HVAC - room, duct and refrigerant
equipment
1 Electronic assemblies - thermal management, temperature compensation
1 Process control - temperature regulation
1000V, 375 alpha provides 10X greater
sensitivity and signal-to-noise. Both
1000V and 100V provide interchangeabilities of ±0.6°C or better from -100°C to
100C, and ±3.0°C at 500°C.
