Platinum Resistance Temperature Detector M 422
M series PRTDs are especially robust and 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 -70°C to +500°C (continuous operation)
(temporary use to 550°C possible)
Tolerance Class B: -70°C to +500°C
Tolerance Class A: -50°C to +300°C
Tolerance Class 1/3 B: 0°C to +150°C
Temperature coefficient TC = 3850 ppm/K ; 3750 ppm/K available
on request

Welding, Crimping and Brazing
Lead lengths (L) 10mm ±1mm
Longterm stability max. R0-drift 0.04% after 1000 h at 500 °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 500°C
Self heating 0.3 K/mW at 0°C
Response time water current (v= 0.4m/s): t0.5 = 0.07s
t0.9 = 0.20s
air stream (v= 2m/s): t0.5 = 3.2s
t0.9 = 11s
Measuring current 100: 0.3 to 1.0mA
500: 0.1 to 0.7mA
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.
