Platinum Resistance Temperature Detector HM 220 HM 220 type platinum sensors are characterised by long-term stability, precision over a broad temperature range and compatibility. The main feature is the small design. They are used in particular for applications with high consumption volumes, e.g. white goods and heating power. Nominal Resistance R0 100 Ohm at 0°C Toler ance DIN EN 60751 1996-07 Class B Class A Tolerance DIN EN 60751 2009-05 F 0.3 F 0.15 Or der Number Plasticbag 32 208 787 32 208 788 The measuring point for the nominal resistance is defined at 6mm from the end of the sensor body. Specification DIN EN 60751 Temperature range -70°C up to +600°C Tolerance Class B: -70°C up to 600°C Tolerance Class A: -50°C up to 300°C Temperature coefficient TCR = 3850 ppm/K Leads Pd alloy with Pt coating wire Lead lengths (L) 8mm ±1mm Long-term tests R0- Drift after 1000h at 600°C (energized) < 0,24% (Unhoused chip in standard atmosphere.) Environmental conditions Unhoused for dry environmental only 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 Insulation resistance > 100 MΩ at 20°C; > 1 MΩ at 600°C Self heating 0.2 K/mW Response time Water current (v= 0.4m/s): Air stream (v=2 m/s): t0.5 = 0.05s t0.9 = 0.14s t0.5 = 3.0s t0.9 = 10s Measuring current 0.1 to 1mA (self heating has to be considered) Note Other tolerances, values of resistance and wire lengths are available on request.
