The most common device for the measurement of load, pressure, torque, and even piezo-resistive (low frequency) acceleration is the strain gauge transducer. As a transducer, which converts a measured ...

Before jumping into a discussion of amplifiers and signal-conditioning circuitry, it is worthwhile to quickly review strain gauges. By definition, “strain” is an alteration due to an external force. A ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

The “DAQ on a Stick, Strain Gauge with Programmable IN-Amp” is one of a series of reference designs highlighting Intersil’s precision products with different microcontrollers. This reference design is ...

Many conventional strain gages are similar in appearance to Figure 1. A serpentine pattern etched into a metal foil creates a relatively high resistance in a small space. The foil is bonded to a thin ...
