Abstract
A semi-conductor type accelerometer features the provision of four piezo resistors on the surface of a flexible beam which interconnects the main body portion with a weight or mass which is adapted to cause the beam to flex under the application of an accelerative force. The resistors are subject to essentially the same ambient conditions whereby thermally induced drift is obviated while a high output for a given amount of beam flexure is obtained.
