Temperature sensors
MULTICAL
801 uses either Pt100 or Pt500 temperature sensors according to EN 60751 (DIN/IEC 751). A Pt100 or
Pt500 temperature sensor respectively is a platinum sensor, of which the nominal ohmic resistance is 100.000
Ω
and 500,000
Ω
at 0.00
°
C and 138.506
Ω
and 692,528
Ω
at 100.00
°
C respectively. All ohmic resistance values are
determined in the international standard IEC 751, applying to Pt100 temperature sensors. The ohmic resistance
values of Pt500 sensors are five times higher. The tables below include resistance values for each degree celcius
in
[Ω]
for both Pt100 and Pt500 sensors:
