Nominal Resistance R0	Tolerance DIN EN 60751 1996-07	Tolerance DIN EN 60751 2009-05	Order Number Plastic Box
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)

El punto de medición para la resistencia nominal se define a 4 mm del extremo del cuerpo del sensor.

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°c (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 in housings also as clean MI-type possible, above 650 no reducing atmosphere, free air admission necessary
Insulation Resistance	>100 MΩ at 20°c; >2 MΩ 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.
