Product specication
Silicon temperature sensors
KTY81-2 series
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
CHARACTERISTICS
Tamb =25 °C, in liquid, unless otherwise specied.
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.
