Platinum Resistance Temperature Detector L 220 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 Toler ance DIN EN 60751 1996-07 Clas s 1/ 3 B Class A Class B Tolerance DIN EN 60751 2009-05 F 0,1 F 0,15 F 0,3 Class B F 0,3 F 0,15 1000 Ohm at 0°C Class A Or der Number Plastic Box 32 207 588 32 207 584 32 207 400 32 207 733 32 207 738 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 Tolerance Class 1/3 B: 0°C to +150°C Temperature coefficient TCR = 3850 ppm/K Leads AgPd- wire Lead lengths (L) 10mm ±1mm Long-term stability max. R0-drift 0.04% after 1000 h at 400°C 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= 0.4 m/s): air stream (v= 2 m/s): t0.5 = 0.06s t0.9 = 0.20s t0.5 = 3.0s t0.9 = 13.0s 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.
