| Nominal Resistance R0 | Tolerance DIN EN 60751 1996-07 | Tolerance DIN EN 60751 2009-05 | Order code |
| 100 Ohm at 0°C | Class B ( to 650°C) | F 0.3 (to 650°C) | 32 208 228 |
Class 2B (to 850°C) | F 0.6 (to 850°C) |
Specification | DIN EN 60751 |
Temperature Range | -70°C up to +850°C Tolerance Class B: -70°C up to +650°C Tolerance Class 2B: -70°C up to +850°C |
Temperature Coefficient | TC = 3850 ppm/K |
Leads | Pt- wire |
Lead Length (L) | 6mm +1mm |
Long-term Tests | 1000h at 850 (energized, open) smaller then the allowed deviation according to DIN B. 1000 h at 650°C(under current as clean MI-type) smaller then the allowed deviation according to DIN B |
Vibration Resistance | at least 40g acceleration with 8ms half sine wave signal, depends on the installation |
Shock Resistance | at least 100g acceleration at frequencies from 10Hz up to 2000Hz, depends on the installation |
Environmental Conditions | Unhoused for dry environment only, Up to 650°C as clean MI-type possible, above 650 no reducing atmosphere, free air admission necessary |
Insulation Resistance | >100MΩ at 20°C; >2MΩ at 650°C |
Self Heating | 0.2 K/mW |
Response Time | Water current (v= 0.4m/s): t0.5 = 0.05s t0.9 = 0.17s Air stream (v= 2m/s): t0.5 = 3.3s t0.9 = 13.0s |
Measuring Current | 20°C max. 5mA; 850°C max. 2.8mA (self heating has to be considered) |
Note | Other tolerances,values of resistance and wire lengths are available on request. |
