Question

A force sensor has as its output a change in resistance. The sensor forms one leg (Ri) of a basic Wheatstone bridge. The sensor resistance with no force load is 200 2, and its static sensitivity is 0.2 ОЛ. Each arm of the bridge is initially 200 Ri R2 0) 14 13 R3 1s o O V-10 V Determine the bridge output for applied loads of 100, 200, and 350N. The bridge is operated as a deflection bridge, with an input voltage of 10V as shown in the above figure. Determine the current through the sensor. Repeat step 1 and 2 with Rm-10K Ω and R,-600 Ω as showing the following figure. 1. 2. 3. 11n Ri 12 l0k2 V 14 13 R3 Is y,-10 6000 Fig. 5
