Platinum Resistance Temperature Detector LN 222 L series PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy over a large temperature range are vital. Typical applications are Automotive, White goods, HVAC, Energy management, Medical and Industrial equipment. Nominal Resistance R0 100 Ohm at 0°C 1000 Ohm at 0°C Tolerance DIN EN 60751 1996-07 Class A Class B Class A Class B Tolerance DIN EN 60751 2009-05 F 0,15 F 0,3 F 0,15 F 0,3 Order Number Plastic Bag 32 207 771 32 207 770 32 207 773 32 207 772 The measuring point for the nominal resistance is defined at 8mm from the end of the sensor body. Specification DIN EN 60751 (according to IEC 751) Temperature range -50°C to +400°C (continuous operation) Tolerance Class B: -50°C to +400°C Tolerance Class A: -50°C to +300°C Temperature coefficient TCR = 3850 ppm/K Leads Ni- silvercoated Recommend connection technology: Soft soldering and Crimping Lead lengths (L) 10mm ±1mm Vibration resistance at least 40g acceleration at 10 to 2000 Hz, depends on installation Shock resistance at least 100g acceleration with 8ms half sine wave, depends on installation Environmental conditions unhoused for dry environments only Insulation resistance > 100 MΩ at 20°C; > 2 M Ω at 400°C Self heating 0.4 K/mW at 0°C Response time water current (v= 0.4m/s): air stream (v= 2m/s): t0.5 = 0.05s t0.9 = 0.15s t0.5 = 3.0s t0.9 = 10.0s Measuring current 100Ω: 0.3 to 1.0mA 1000Ω: 0.1 to 0.3mA (self heating has to be considered) Note Other tolerances, values of resistance and wire lengths are available on request.
