Platinum Resistance Temperature Detector HL 220 HL 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 Tolerance DIN EN 60751 1996-07 Tolerance DIN EN 60751 2009-05 Order Number Plastic Box 1000 Ohm at 0°C Class 2B F 0.6 32 208 779 The measuring point fort he nominal resistance is defined at 6mm from the end oft he sensor body. Specification DIN EN 60751 Temperature range -70°C up to +750°C Tolerance Class 2B: -70°C up to +750°C Temperature coefficient TC = 3850 ppm/K Leads Pt coated NiCr- wire Lead lengths (L) 8mm ±1mm Long-term tests R0- Drift after 1000h at 750°C (energized) < 0,24% (Unhoused chip in standard atmosphere.) Environmental conditions Unhoused for dry environmental only, above 500°C no reducing atmosphere, free air admission is necessary. Assembly can influence the long term stability! 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 M at 20 °C; > 1 M at 650 °C Self heating 0.2 K/mW Response time Water current (v= 0.4m/s): Air stream (v= 2m/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.
