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 100Ω and 0.1mA for 500Ω or 1kΩ. SDT310AP can be used as hot-film sensor. Maximum specified current is 100mA when using under self-heating condition.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.

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.

Pt100 Resistance - Temperature Characteristic (JIS C1604-1997)
100 at 0°C
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.
