* T.C.R. measuring temperature: 0°C/+100°C.
**
Thermal time constant and thermal dissipation constant are values measured in stationary air and are typical values, which are values of elements and vary with connecting or fixing methods.
*** The electricity which it is charged with in the element is moved to the range that rise in temperature due to a self-heat generation can be ignored. Recommended measuring currents
are 1mA for 100Ωand 0.1mA for 500Ωor 1kΩ. SDT310AP can be used as hot-film sensor. Maximum specified current is 100mA when using under self-heating condition.

Note: Desired temperature values are obtained by adding temperatures in the vertical and horizontal axes.
When calculating a resistance value of 105°C, read the value in the column where 100°C in the
vertical axis and 5°C in the horizontal axis cross. The value will be 140.40Ω. The value for 500Ω
at 0°C will be the value obtained by multiplying the resistance value in this table by 5. Similarly,
the value for 1KΩ at 0°C will be the value obtained by multiplying the resistance value by 10.

Note: Desired temperature values are obtained by adding temperatures in the vertical and horizontal
axes. When calculating a resistance value of 105°C, read the value in the column where 100°C in
the vertical axis and 5°C in the horizontal axis cross. The value will be 140.40Ω. The value for 500Ω
at 0°C will be the value obtained by multiplying the resistance value in this table by 5. Similarly,
the value for 1KΩ at 0°C will be the value obtained by multiplying the resistance value by 10.
