Pressure sensors convert mechanical force into electrical signals through strain gauge technology. A typical pressure sensor contains four strain gauges arranged in a Wheatstone bridge circuit. When pressure causes the diaphragm to deflect, all four resistors change proportionally, generating a precise output signal.
Sensor sensitivity is commonly expressed in millivolts per volt (mV/V). Most pressure sensors provide outputs ranging from 1–3 mV/V, while high-sensitivity models can reach 10–30 mV/V. The full-scale output is calculated by multiplying sensor sensitivity by the excitation voltage. For example, a 3 mV/V sensor powered by 10 VDC produces a full-scale output of 30 mV.
Understanding Wheatstone bridge principles helps engineers improve measurement accuracy and system reliability. ORR Sensor Co., Ltd. provides high-performance pressure sensors designed for industrial automation, process control, and precision measurement applications worldwide.
