Platinum Resistance Temperature Detector L 1020
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.
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 1/3B: 0°C to +150°C
Temperature coefficient TC = 3850 ppm/K
Leads AgPd- wire
Lead lengths (L) 10mm ±1mm
Long- term stability max. R0-drift 0.04% after 1000h 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 M at 20°C; > 2 M at 400°C
Self heating 0.2 K/mW at 0°C
Response time water current (v = 0.4m/s): t0.5 = 0.12s
t0.9 = 0.30s
air stream (v = 2m/s): t0.5 = 6.0s
t0.9 = 20.0s
Measuring current 100: 0.3 to 1.0mA
1000: 0.1 to 0.3mA
(self heating has to be considered)
Note Other tolerances, values of resistance and wire
lengths are available on request.
