HEL-705-U-1-12-C3

Temperature Sensors Platinum RTDs FEATURES Linear resistance vs temperature Accurate and Interchangeable Excellent stability Small for fast response Wide temperature range 3-packaging options TYPICAL APPLICATIONS HVAC - room, duct and refrigerant equipment Electronic assemblies - thermal management, temperature compensation Process control - temperature regulation MOUNTING DIMENSIONS (for reference only) HEL-700 Ribbon Lead ORDER GUIDE HEL-700 Thin Film Platinum RTD HEL-700 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. 1000 , 375 alpha provides 10X greater sensitivity and signal-to-noise. Both 1000 and 100 provide interchangeabilities of ±0.6°C or better from -100°C to 100C, and ±3.0°C at 500°C. -U -T 1000 , 0.00375 / /°C 100 , 0.00385 / /°C DIN Standard -0 -1 ±0.2% Resistance Trim (Standard) ±0.1% Resistance Trim (Optional) -A -B -C Radial Ribbon Lead Radial Chip SMT Axial Flip Chip (1000 ONLY) Fig. 1: Linear Output Voltage HEL-700 Radial Chip Temperature Fig. 2: Adjustable Point (Comparator) Interface HEL-700 SMT (Axial) Flip Chip Honeywell MICRO SWITCH Sensing and Control 1-800-537-6945 USA 1-815-235-6847 International 1-800-737-3360 Canada 85 Temperature Sensors Platinum RTDs FUNCTIONAL BEHAVIOR RT R0(1+AT+BT2−100CT3+CT4) RT Resistance ( ) at temperature T (°C) R0 Resistance ( ) at 0°C T Temperature in °C A + B − CT0°C −5.775×10-7 −4.183×10-12 RESISTANCE VS TEMPERATURE CURVE RTD.
