Product Description

dimphy 108sp Thermostatic Bimetal strip

Common Name: Truflex P675R, Chace 7500,Telcon200,   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.
