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)

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) |
