The unbonded strain gauge accelerometer of Figure 8.20 and Section 9.1.2 has a natural fre- quency of 175 Hz and an input range of 0 to 5g. Given that the strain due to prestressing is twice the maximum acceleration-induced strain, use the strain gauge data given below to calculate the range of the bridge output voltage. Resistance Gauge factor Maximum current Length at zero acceleration = 120 92 = 2.1 = 50 mA = 2.3 cm Figure 8.20 Practical elastic sensing elements using strain gauges: (a) Cantilever load cell (b) Pillar load cell (c) Torque sensor (d) Unbonded strain gauge accelerometer.
