100 at 0°C±0.12% (or ±0.3°C) and 138.50 at +100°C±0.22% (or ±0.8°C) per DIN 43760, Class B.
You can select anyvalue from 50 to 5 Kilohms in tolerancesfrom 1/4 DIN (±0.03%) to 2 x DIN (±0.24%).
Rt is defined by IEC Standard, pub. 751:alpha = 0.00385 ohm/ohm/°C*
Rt = [1+At+Bt + C(t-100°C)t ]
Rt = (1+At+Bt )
A = 3.79782 x 10B = 6.502 x 10C = 4.3735 x 10
Fixed points are in degrees Celsius, = 0°CThe other (Ref.) temperature is + 100°C, butany temperature can be used in the equationwith respect to Base 0°C. The PRC100 Std.Ref. follows a well-defined theoreticalcurve and linear slope from Base 0°C provingthat most reference points are calculablewithin very close tolerances (Ratio = Rt/ ).

THERMAL TIME CONSTANT
All PRC100 sensors are closely matchedand repeatable part-to-part. They are ableto consistently reproduce output readingsconsecutively at the same temperaturereference points ... under the sameconditions and in the same direction.
The change in the original resistance ( )at 0° C after 10 cycles to +150°C is lessthan ±0.1°C or ±0.038% max. Shelf lifestability is ± 0.002%/yr. at 25°C (no load).
The PRC100 is ideal as a compensatorto offset drift or negative self-generatingchanges in resistance as a result of anexcitation of power to 0.25 watt at +125°Cto zero power at +150°C.
The time required for the PRC100 sensorto indicate 63.2% of a new impressedtemperature from a step change of 0°Cto +100°C can be customized to < 1 second
