*1 T.C.R.Mesuring Temperature : 0
/ +100
*2 Thermal time constant and dissipation constant are values measured
in stationary air and are typical values,which are values of elements
and vary with connecting or fixing methods.
*3 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 100
and 0.1mA for 500
or 1k.SDT310AP
can be used as hot - film sensor . Maximum specifired current
is 100mA when using under self - heating condition.
