Silicon temperature sensors

KTY82-2 series

CHARACTERISTICS

Notes

1.The thermal time constant is the time taken for the sensor to reach 63.2% of the total temperature difference.

For example, if a sensor with a temperature of 25

°C is moved to an environment with an ambient temperature of

100

°C, the time for the sensor to reach a temperature of 72.4 °C is the thermal time constant.

2.Inert liquid, e.g. FC43 manufactured by the 3M company.
