Thermostatic bimetal strip 5j20110

Thermostatic bimetal strip 5j20110

Common Name: Truflex P675R, Chace 7500,Telcon200, Kanthal 200)
Bimetallic 108sp holds very high thermal sensitivity and higher resistivity,but the modulus of elasticity and allowable stress is lower,it can improve the sensitivity of the instrument,decrease the size and increase the force.
