According to temperature sensing element type , temperature sensor
can be made with ceremic element ,for example NTC sensor and
PTC sensor , with RTD elements , for example PT **0 ,
PT***0 , with semiconductor element , for example DS*8B*0 sensor ,
or KTY sensor . it can also be a
thermal couple according to electric
potential between two different metal material
. Different type temperature sensor available with
custom design .
