Readings in % refer to the measuring span
For a correct determination of the overall measuring error, both sensor and transmitter measuring deviations have to be
considered.
1) For detailed specifications for Pt100 sensors, see Technical Information IN 00.17 at www.wika.com.
2) The temperature transmitter should therefore be protected from temperatures over 85 °C
3) For measuring spans smaller than 50 K additional 0.1 K
4) ± 0.2 % for measuring ranges with a lower limit less than 0 °C
5) Use resistance thermometers with shielded cable, and ground the shield on at least one end of the lead, if the cables are longer than
30 m or leave the building.
