Bimetallic Strip-(ELS-BIMET)

Bimetallic Strip - For demonstrating the differential expansion of two metals by the curvature produced when the strip is heated in a flame. Comprises a 200 x 15mm strip of brass and steel rivetted together with heat resistant rivets and mounted in a well finished wooden handle. Set of 10 Strips With this kit students can easily apply the effect of temperature change on a bi-metal strip. The kit consists of a class set of 10 bi-metal strips measuring 100 x 8 x 0.5 mm securely attached to wooden supports. The device can be held in a standard laboratory clamp and with a few leads, battery or power supply, buzzer, and some crocodile clips students can invent a fire alarm while revising simple circuit work. The apparatus can form the basis of many other design projects such as thermostats or investigations into expansion. -
