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.
