[vc_row][vc_column][vc_column_text text_larger=”no”]
Mseries 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.

Long-term Stability | max. R0-drift 0.04% after 1000 h at 500°C |
Vibration Resistance | at least 40 g acceleration at 10 to 2000 Hz, depends on installation |
Shock Resistance | at least 100 g acceleration with 8ms half sine wave, depends on installation |
Environmental Conditions | Unhoused for dry environment only |
Insulation Resistance | > 100M°C at 20°C; > 2 M°C at 500°C |
Self Heating | 0.4 K/mW at 0°C |
Response Time | Water current (v= 0.4m/s): t0.5 = 0.05s; t0.9 = 0.15s Air stream (v= 2m/s): t0.5 = 3.0s; t0.9 = 10.0s |
Measuring Current | 100°C: 0.3 to 1.0 mA 500°C: 0.1 to 0.7 mA 1000°C: 0.1 bis 0.3 mA (self heating has to be considered) |
